The rapid development of advanced technologies like satellite communication, navigation, remote sensing, and Non-Geostationary Earth Orbit (Non-GEO) satellite systems with extensive application in onshore, aerial, and maritime mobile terminals make it essential for mobile satellite service systems to comprehensively consider their propagation characteristics, to maintain reliability. Due to the constant variation in elevation angle and application environment of radio wave propagation path of a mobile satellite service, the mobile terminal generally uses the wide-beam antenna, which is capable of receiving the incoming-wave signals from different directions, including direct signals, reflected signals of ground and sea surface, as well as reflected and scattering signals of various objects. Furthermore, satellite signals could also be shadowed by the buildings and trees along the roadsides. For this reason, the mobile satellite system, unlike the fixed satellite system, must consider the environment effects, including ground reflection and local environment features, in addition to the propagation effect of fixed satellite services.
