Abstract
A system and method for determining a receiver position can include determining a receiver position based on a set of satellite observations, determining the receiver position based on sensor measurements, determining a satellite observation discontinuity; based on the satellite observation discontinuity, determining a second receiver position.
Claims9
A system for determining a receiver position, comprising:
- a positioning engine executing on a computing system collocated with a receiver, the positioning engine comprising:
- an observation monitor configured to receive a set of satellite observations from a set of global navigation satellites;
- an integer fixing module configured to determine an integer-valued carrier phase ambiguity associated with each satellite of the set of global navigation satellites;
- a reconvergence module configured to determine the cycle slip based on IMU data acquired during a phase lock loss period and a receiver position determined before the phase lock loss period;
- and
- a position filter configured to estimate a position of the receiver based on the satellite observations with the associated integer-valued carrier phase ambiguities removed.
