Abstract
A system and method for determining a GNSS receiver position includes receiving a first and a second set of satellite observations; determining a first and second ambiguity set associated with a first and second transformation respectively; determining cross-validated ambiguities between the first and second ambiguity sets; and determining the GNSS receiver position based on at least one of the first or second ambiguity sets.
Description
Claims
  • 1. A method comprising: receiving a first and a second set of satellite observations;determining a first ambiguity set associated with the first set of satellite observations and a second ambiguity set associated with the second set of satellite observations;transforming the first and second ambiguity sets to a shared intersection space;determining whether ambiguities from the first and second ambiguity sets are valid based on a comparison of the first and second ambiguity sets in the shared intersection space; andwhen the ambiguities are valid, determining a position of a GNSS receiver based on at least one of the first or second ambiguity sets.
