Abstract: Focused on the mission of remote sensing geophysics parameters with GPS-reflection receiver set on LEO satellite,the reflection events are simulated taking into account the scan mode of satellite and receiver antenna parameters based on simplified general perturbation-4(SGP4) orbit prediction model.The impacts of satellite orbit parameters,orbit inclination,orbit height,argument of perigee and right ascension of ascending on the distribution and number of ocean reflection events are discussed through simulation.Moreover,the total reflection events including ocean and land reflection derived from single LEO satellite is simulated and analyzed.The results can be referenced when designing the LEO satellite orbit parameters and receiver antenna parameters.
