| Abstract: | The GPS radio occultation simulation software SHAOOS which was designed by Shanghai Astronomical Observatory and the Mathematics Department, Wenzhou Normal College in 2002 is based on the ray-tracing technique and on the refraction theory. SHAOOS provides multifunctional computation simulations for GPS/LEO radio occultation technique research. The basic mathematical method, physical background, program structure and application functions of SHAOOS are briefly reviewed in this paper. |
