Claims
- 1. A system comprising:
a GNSS user receiving device; a radio communications device; a single antenna shared by the GNSS user receiving device and the radio communications device; and a signal splitter and switch for selectively connecting the single antenna to the GNSS user receiving device or to the radio communications device.
- 2. The system of claim 1, further comprising a means to enhance performance of the GNSS user receiving device based on tracking of signals available outside the GNSS frequency band of operations.
- 3. The system of claim 1, wherein the radio communications device comprises a VHF radio communications device installed on an aircraft.
- 4. The system of claim 3, further comprising a means to enhance performance of the GNSS user receiving device based on tracking of signals available outside the GNSS frequency band of operations.
- 5. The system of claim 1, wherein the radio communications device comprises a VDL Mode 4 radio communications device installed on an aircraft.
- 6. The system of claim 5, further comprising a means to enhance performance of the GNSS user receiving device based on tracking of signals available outside the GNSS frequency band of operations.
- 7. The system of claim 5, wherein the GNSS user receiving device is employed for the limited purpose of generating appropriate time signals.
- 8. A system comprising:
a plurality of communications devices, each with an embedded GNSS user receiving device; and a single separate antenna to which each communications device with the embedded GNSS user receiving device is connected locally; wherein the plurality of communications devices with the embedded GNSS user receiving devices exchange RF, IF or sampled-data equivalent signals associated with the GNSS, and the embedded GNSS user receiving devices process said exchanged signals in addition to the GNSS signals received via said locally-connected antenna.
