Field: Measurement (Instruments)
Classification: CPC G | IPC G

Claim 0:
1. A method for navigation using differential carrier phase measurement of low earth orbit (LEO) satellite signals, the method comprising:
receiving, by a device, one or more low earth orbit (LEO) satellite signals;
receiving, by the device, observables for the one or more LEO satellite signals from a base;
determining, by the device, 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;
correcting, by the device, 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
determining, by the device, at least one navigation observable using a corrected position estimate.
