In the course of determination orbit, the on-board GPS surveying plays a crucial role, that is the quality of the on-board GPS data.

Solution of ambiguity and cycle slip for satellite-borne GPS phase data with wide-lane/narrow-lane method

A study of orbit determination methods using undifferenced dual-frequency onboard GPS P codes;

Study and Software Implementation of GPS Data Pre-processing and Onboard GPS Kinematic Orbit Determination;

Based on the geometric, dynamic and reduced dynamic precise orbit determination (POD), a kinematic POD by the onboard GPS zero-differential phase observations was discussed and programmed.

On the basis of the theory of on-board GPS precise orbit determination (POD), having analyzed and discussed functional model and stochastic model of on-board GPS low earth orbit (LEO) satellite, the linear combination, zero-differential and differential functional model form and their advantages and disadvantages are put forward.

The on-board GPS technique is becoming a main method for Low Earth satellites orbit determination.

In the course of satellite-borne GPS carrier phase measurement,cycle-slip detection and repair plays a very important role in the GPS station precision.
