Mobile Satellite Communication Networks (Repost)

Until very recently, geostationary satellites have been used as a sole basis for the provision of mobile satellite services. However, the launch of satellite personal communication services (S-PCS), which make use of non-geostationary satellites, has provided a new dimension to the mobile satellite communications industry. The introduction of S-PCS comes at a time when the global mobile market is experiencing phenomenal growth. This is set to continue with the introduction of 3G, including UMTS (Universal Mobile Telecommunications System), which will provide mobile multimedia services, similar to those available on personal computers.
