Simulation of the Impacts of Single LEO Satellite Orbit Parameters on the Distribution and Number of Occultation Events

Focused on the task of carrying out GPS occultation observations with a receiver set on LEO satellite, this paper developes the LEO orbit simulation system based on which the occultation events can be simulated taking into account the geometric relationship of the satellites and the field of view of the receiver antenna. In this paper, the impacts of 4 types of LEO orbit parameters—argument of latitude(AOL), right ascension of ascending node(RAAN), orbit height and inclination—on the distribution and number of occultation events a single LEO satellite observed are discussed through simulation and some conclusions are drawn.
