The present technology relates to an information processing device, an information processing method, and a program, and, in particular, to a technology concerning presentation of information regarding a ground station.
A communication system for performing communication between a satellite station and a ground station installed on the ground is known.
PTL 1 mentioned below discloses a system in which, while a satellite station that substantially circles around the center of the earth along an orbit is tracked by a ground antenna of a ground station installed on the ground of the earth, communication is performed via propagation of radio waves between the ground antenna and a satellite antenna of the satellite station.
A major concern for a satellite business proprietor that intends to increase the number of launches of satellite stations is an insufficient number of ground stations that are available for communication with the satellite stations. Although ground stations owned by the proprietor itself and the like may be sufficient for the communication with the satellite stations when a first few launches of satellite stations have been done, use of ground stations provided by ground station providers all over the world will be necessary when the number of satellite stations launched is further increased.
Before employing a ground station provided by a ground station provider, the satellite business proprietor needs to consider whether the ground station provided by the ground station provider meets specifications for the communication with the satellite station of the proprietor, how much cost will be needed for use thereof, and so on.
Thus, satellite business proprietors typically send a document such as an RFI (Request for Information) or an RFP (Request for Proposal) to ground station providers use of which is to be considered, to acquire important information regarding ground stations from the ground station providers.
However, it is not easy for a satellite business proprietor to find, from among a number of ground station providers, a company that owns a ground station having such specifications as to allow communication with a satellite station owned by the proprietor. Continuing to send documents such as RFIs or RFPs to ground station providers to acquire important information regarding ground stations until a proper ground station provider is found is a burden to the satellite business proprietor, and is a major cause of an extended lead time for preparation of a ground station and a start of operation thereof.
Thus, an object of the present technology is to provide a system for a satellite business proprietor that facilitates a search for a ground station having such specifications as to allow communication with a satellite station of the satellite business proprietor, and that facilitates acquisition of important information regarding a retrieved ground station.
An information processing device according to the present technology includes a user interface section that performs a process of presenting a specification page for specifying a search condition with respect to a channel of a downlink and an uplink between a satellite station and a ground station, a process of presenting a search result page that presents a list of ground stations retrieved as a result of a search based on a condition entered on the specification page, the search result page allowing a ground station to be specified and entered, and a process of presenting a communication plan page that displays a communication plan employing one or more ground stations specified on the search result page.
Thus, the list of the ground stations retrieved as a result of the specification of the search condition with respect to the channel is presented, and if a ground station(s) is selected from the presented list, a communication plan in which information regarding the selected ground station(s) is reflected is automatically created and is presented as the communication plan page.
In the information processing device according to the present technology, it is conceivable that the specification page presented by the user interface section has a plurality of pages including a band specification page that allows specifications concerning a band for the downlink and a band for the uplink between the satellite station and the ground station, and a communication specification page that allows setting up of one of or both a communication configuration for the band for the downlink selected on the band specification page and a communication configuration for the band for the uplink selected on the band specification page.
This makes it possible to specify the frequency bands of the downlink and the uplink and the communication configurations for the frequency bands, as the search conditions for ground stations.
In the information processing device according to the present technology, it is conceivable that the user interface section performs, in response to an operation performed on the search result page to request detailed information regarding a ground station, a process of presenting a detail page displaying the detailed information regarding the corresponding ground station.
This makes it possible to check the detailed information regarding the retrieved ground station.
It is conceivable that the information processing device according to the present technology further includes a search section that performs a process of searching for ground stations on the basis of the search condition entered on the specification page, to obtain a search result.
This enables the searching process to be accomplished in the information processing device.
It is conceivable that the information processing device according to the present technology further includes a plan generation section that performs a process of generating a communication plan on the basis of information regarding the one or more ground stations specified on the search result page.
This enables the plan generation process to be accomplished in the information processing device.
In the information processing device according to the present technology, it is conceivable that a specification of a search condition with respect to a channel of a downlink alone is enabled on the specification page.
This makes it possible to perform a search for ground stations on the basis of a search condition(s) with only the downlink set, without consideration given to information regarding the uplink.
In the information processing device according to the present technology, it is conceivable that the specification page allows a search request to be made without a specification of a search condition with respect to a channel of a downlink or an uplink.
This makes it possible to perform a search for ground stations in a state in which a search condition(s) with respect to a channel of only one of the downlink and the uplink is specified, allowing a search for ground stations to be performed without specifying search conditions with respect to the channels of both the downlink and the uplink.
In the information processing device according to the present technology, it is conceivable that a specification of at least any one of a bandwidth, a modulation method, and a data rate is enabled on the communication specification page.
This makes it possible to perform a search for ground stations with the bandwidth, the modulation method, the data rate, etc., set as the search conditions.
An information processing method according to the present technology is performed by an information processing device. The method includes a process of presenting a specification page for specifying a search condition with respect to a channel of a downlink and an uplink between a satellite station and a ground station, a process of presenting a search result page that presents a list of ground stations retrieved as a result of a search based on a condition entered on the specification page, the search result page allowing a ground station to be specified and entered, and a process of presenting a communication plan page that displays a communication plan employing one or more ground stations specified on the search result page.
A program according to the present technology is a program for causing an information processing device to perform the above-described processes.
The present technology makes it possible to easily search for ground stations use of which is to be considered, and to easily acquire information regarding retrieved ground stations.
Note that the advantageous effects mentioned above are not necessarily restrictive, and that any of the advantageous effects described in the present disclosure may be achieved.

As a result, the band specification page 200 as illustrated in
If selection operations by the user on the first band specification area 201 and the second band specification area 202 are detected in a state in which the band specification page 200 is controlled to be presented on the user terminal 2, the management server 1 specifies a channel of the downlink and the uplink according to the selection operations.
The band specification page 200 continues to be presented on the user terminal 2 until the management server 1 detects an operation for moving to the communication specification page 300 in step S102.
If the management server 1 detects an operation for moving to the communication specification page 300 in step S102, the management server 1 proceeds to step S103, and performs control for presenting the communication specification page 300 based on the specified frequency band(s).
If a selection operation on the communication configuration button 203 is detected, the management server 1 generates the web page data in which the specification of the channel on the band specification page 200 is reflected, and performs control for presenting the web page data on the user terminal 2.
As a result, the communication specification page 300 as illustrated in
If input and selection operations for the communication configuration are detected in a state in which the communication specification page 300 is controlled to be presented on the user terminal 2, the management server 1 sets up the communication configuration for the frequency band of the downlink selected on the band specification page 200, and the communication configuration for the frequency band of the uplink selected on the band specification page 200, according to the operations.
In addition, if a selection operation on the save button 342 is detected, the management server 1 records, on the DB 3, the search condition(s) such as the frequency band(s) of the specified channel and the communication configuration(s) thereof so as to be associated with the user ID in the case where the user is logged on the present system.
At this time, in the case where the user is not logged on the present system, the management server 1 causes a login screen to be presented on the user terminal 2. The user needs to perform the login process via the user terminal 2. If login request information is received from the user terminal 2, a login process is performed in the management server 1.
In addition, if a selection operation on the save button 342 is detected, the management server 1 records the search condition(s) specified with respect to the present channel. Then, the management server 1 returns to step S101 and performs control for presenting the band specification page 200 on the user terminal 2.
Thus, search conditions can be specified with respect to a plurality of channels.
The communication specification page 300 continues to be presented on the user terminal 2 until the management server 1 detects an operation for moving to the search result page 400 in step S104.
If a search request by the operation for moving to the search result page 400 is detected in step S104, the management server 1 proceeds to step S105 and performs the process of searching for ground stations.
If a selection operation on the search button 340 in
Then, in step S106, the management server 1 performs control for presenting the search result page 400 based on the searching process.
The management server 1 generates web page data on the basis of the information regarding the retrieved ground station(s), and performs control for presenting the web page data on the user terminal 2.
As a result, the search result page 400 as illustrated in
If a selection operation on the ground station selection section 409 in any ground station presentation section 403 is detected in a state in which the search result page 400 is controlled to be presented on the user terminal 2, the management server 1 determines that the selected ground station is a ground station to be used when generating the communication plan.
In the state in which the search result page 400 is controlled to be presented on the user terminal 2, the management server 1 executes a monitoring loop with respect to steps S107 and S108.
If an operation for requesting details about any ground station is detected in step S107, the management server 1 proceeds to step S109 and performs control for presenting the detail page 500 of the selected ground station.
If a selection operation on the detail selection button 408 in any ground station presentation section 403 is detected, the management server 1 acquires the web page data of the detail page 500 of the selected ground station from the DB 3, and performs control for presenting the web page data on the user terminal 2.
As a result, the detail page 500 as illustrated in
The detail page 500 continues to be presented on the user terminal 2 until the management server 1 detects a page back operation in step S110.
If the page back operation is detected in step S110 in a state in which the detail page 500 is presented, the management server 1 proceeds to step S106, and performs control for presenting the search result page 400 on the user terminal 2.
Thus, the user is able to consult the information regarding the ground station presented on the detail page 500, and then proceed to select a ground station to be used for the creation of the communication plan on the search result page 400.
Returning to the monitoring loop, if a communication plan request operation by a selection operation on the communication plan creation button 411, for example, is detected in step S108, the management server 1 proceeds to step S111.
In step S111, the management server 1 acquires information regarding the ground station(s) selected on the search result page 400.
Then, in step S112, the management server 1 performs a communication plan generation process of generating web page data representing the communication plan, on the basis of the information regarding the ground station(s) selected on the search result page 400. The information regarding the ground station(s) used for the communication plan is information for acquiring or generating the items to be presented on the communication plan page 600.
Then, in step S113, the management server 1 performs control for presenting the web page data generated in step S112, on the user terminal 2.
As a result, the communication plan page 600 as illustrated in
Further, according to the present technology, not only the list of the ground station(s) retrieved on the basis of the search conditions specified on the band specification page 200 and the communication specification page 300 is presented on the search result page 400, but also the communication plan with respect to the selected ground station(s) can further be created by selecting the ground station(s) from the list presented on the search result page 400.
The management server 1 finishes the procedure of
The management server 1 finishes the control for presenting each of the pages on the user terminal 2 as illustrated in
Note that, as described above with reference to
The ground station information providing system according to the present embodiment is implemented by the above-described processes of the management server 1 as illustrated in
Note that the processes of the management server 1 in the ground station information providing system may also be modified as follows.
For example, although, in
In this case, the management server 1 performs a search for ground stations on the basis of the currently entered search conditions each time an entry of the communication configuration is made on the communication specification page 300. Then, the management server 1 performs control for presenting the number of ground stations that match the search conditions, on the user terminal 2.
Thus, the number of ground stations that match the entered search conditions can be presented as appropriate in, for example, the number-of-ground-stations presentation section 343 of the communication specification page 300 of
The management server 1 described in the foregoing description of the embodiment includes the user interface section 11 that performs the following processes: a process of presenting the specification pages 100 for specifying a search condition or conditions with respect to a channel of a downlink and an uplink between satellite and ground stations; a process of presenting the search result page 400 that presents a list of a ground station or stations retrieved as a result of a search based on a condition or conditions entered on the specification pages 100, the search result page 400 allowing a ground station or stations to be specified and entered; and a process of presenting the communication plan page 600 that displays a communication plan employing one or more ground stations specified on the search result page 400 (see
Accordingly, the list of the ground station(s) retrieved as a result of the specification of the search condition(s) with respect to the channel is presented on the search result page 400, and if a ground station(s) is selected from the presented list, a communication plan in which information regarding the selected ground station(s) is reflected is automatically created and is presented as the communication plan page 600 on the user terminal 2.
Thus, it is possible to easily retrieve, from among a number of ground stations, a ground station(s) that has such specifications as to allow the ground station(s) to communicate with a satellite station owned by the user.
Thus, it is possible to search for a plurality of ground stations together and check the result of the search as a list of ground stations put together, without the need to send a document such as an RFI or an RFP to each of a plurality of ground station providers that own ground stations that can match the conditions. This leads to a significant reduction in time required to search for ground stations that match the conditions desired by the user.
In addition, it is possible to automatically create a communication plan in which information regarding a given ground station(s) is reflected, by selecting the given ground station(s) from the list. In particular, it is also possible to automatically create a communication plan with respect to a plurality of ground stations together, and this leads to significantly saving time and effort for creating a proposal or the like when consideration is given to use of a ground station(s).
As described above, the use of the present system by the user leads to a significant reduction in lead time for preparation of a ground station(s) and a start of operation thereof.
Note that, in the present embodiment, the search section 12 performs the process of searching for ground stations on the basis of the search conditions entered on the specification pages 100, to obtain the search result, while the plan generation section 13 performs the process of generating the communication plan on the basis of the information regarding one or more ground stations specified on the search result page 400 (see
The specification pages 100 presented by the management server 1 according to the embodiment have a plurality of pages including: the band specification page 200 on which specifications concerning respective bands (frequency bands) for the downlink and the uplink between the satellite and ground stations are possible; and the communication specification page 300 on which setting up of one of or both the communication configuration for the band (frequency band) of the downlink selected on the band specification page 200 and the communication configuration for the band (frequency band) of the uplink selected on the band specification page 200 is possible (see S101 and S103 in
This makes it possible to specify the frequency bands of the downlink and the uplink and the communication configurations for the frequency bands, as the conditions for searching for ground stations.
For example, the UHF (Ultra High Frequency) band, the S-band, the X-band, the Ka-band, etc., can be specified as the frequency band of the downlink, and the UHF band, the S-band, etc., can be set as the frequency band of the uplink.
In addition, in the communication configuration for each of the downlink and the uplink, the frequency range, the bandwidth, the modulation method, the maximum data rate, the polarization type, the link availability of the ground station, the minimum value of G/T, the antenna type, the pointing accuracy, etc., can be specified.
Thus, it is possible for the user to specify desired conditions to narrow the search for ground stations, enabling an intention of the user to be more accurately reflected in the search for ground stations.
Further, since the search for ground stations and the creation of the communication plan can efficiently be accomplished as described above, the number of instances of communication between the management server 1 and the user terminal 2 can be reduced to enable a reduction in channel capacity.
The management server 1 according to the embodiment performs the process of, in response to the operation for requesting detailed information regarding a ground station being performed on the search result page 400, presenting the detail page 500 displaying the detailed information regarding the ground station (see S109 in
The presentation of the detail page 500 on the user terminal 2 enables the user to check the detailed information regarding the retrieved ground station. This makes it possible to consult the detailed information regarding each ground station when selecting a ground station(s) to create the communication plan.
Accordingly, the user is able to give careful consideration to which ground station(s) to use when creating a communication plan, enabling creation of a communication plan in which an intention of the user is more accurately reflected.
Regarding the management server 1 according to the embodiment, a specification of a search condition(s) with respect to a channel of a downlink alone is possible on the specification pages 100 (i.e., the band specification page 200 and the communication specification page 300) (see S101 in
This makes it possible to perform a search for ground stations on the basis of a search condition(s) with only the downlink set, without consideration given to information regarding the uplink. In some communications between satellite and ground stations, a downlink is performed while an uplink is not performed. Thus, when the uplink is not to be used, a load on the user can be reduced by omitting a search condition(s) with respect to the uplink.
Regarding the management server 1 according to the embodiment, the specification pages 100 (i.e., the band specification page 200 and the communication specification page 300) allow a search request to be made without a specification of a search condition with respect to a channel of a downlink or an uplink (see S101 in
This makes it possible to perform a search for ground stations in a state in which a search condition(s) with respect to a channel of only one of the downlink and the uplink is specified, allowing a search for ground stations to be performed without specifying search conditions with respect to the channels of both the downlink and the uplink. This enables a more flexible search for ground stations.
While the management server 1 has been described above as an information processing device according to an embodiment of the present technology, a program according to an embodiment is a program for causing an information processing device (e.g., a CPU) to perform the processes performed in the management server 1.
A program according to an embodiment is a program for causing an information processing device to perform the following processes: a process of presenting a specification page or pages for specifying a search condition or conditions with respect to a channel of a downlink and an uplink between satellite and ground stations; a process of presenting a search result page that presents a list of a ground station or stations retrieved as a result of a search based on a condition or conditions entered on the specification page or pages, the search result page allowing a ground station or stations to be specified and entered; and a process of presenting a communication plan page that displays a communication plan employing one or more ground stations specified on the search result page.
That is, this program is a program that causes the management server 1 to perform the processes described above with reference to
This program enables an information processing device to function as the management server 1. Such a program can be recorded in advance on an HDD as a recording medium contained in a device such as a computer device, a ROM in a microcomputer having a CPU, or the like. In addition, such a program can be stored (recorded) temporarily or permanently in a removable recording medium such as a semiconductor memory, a memory card, an optical disk, a magneto-optical disk, or a magnetic disk. Such a removable recording medium can be provided as what is called packaged software.
Such a program can be installed from a removable recording medium into a personal computer or the like. Alternatively, such a program can be downloaded from a download site via a network such as a LAN or the Internet.
Finally, it is to be appreciated that the foregoing description of the respective embodiments illustrates example embodiments of the present technology, and that the present technology is not limited to the above-described embodiments. Accordingly, it should naturally be understood that, other than the above-described embodiments, various modifications can be made according to design requirements and other factors without departing from the scope of the technical idea of the present technology. It is also to be understood that advantageous effects mentioned in the present specification are merely illustrative and are not restrictive, and there may be other advantageous effects.
