Assignee: THE REGENTS OF THE UNIVERSITY OF CALIFORNIA
Field: Measurement (Instruments)
Classification: CPC G | IPC G

Claim 10:
11. A device configured for navigation using differential carrier phase measurement of low earth orbit (LEO) satellites, the device comprising:
a receiver configured to
receive one or more low earth orbit (LEO) satellite signals, and
receive observables for the one or more LEO satellite signals from a base; and
a controller configured to
determine a position estimate for the device using carrier phase determinations of the one or more LEO satellite signals received by the device and the observables from the base;
correct the position estimate, wherein correcting is based on an integer ambiguity resolution operation and double difference carrier phase determination for the one or more LEO satellite signals; and
determine at least one navigation observable using a corrected position estimate.
