Land Mobile Communications Satellite Missions (LAMOCOSAMIS) Task 4: Hybrid System Concept

摘要

The possibility of a hybrid satellite/terrestrial network for land mobile communication in Europe was assessed. The interdependency of the system parameters makes the problem of satellite mission difficult to approach, and the regulatory context (no frequency allocation for land mobile satellite service in Europe) offers more fields of investigation, as UHF and L-Band have to be considered as candidate frequency bands. It is shown that in L-Band, a capacity of 100 telephone channels is possible with spacecraft of the EUROSTAR class, indicating that a hybrid concept is attractive.
