A geostationary satellite named ETS-V, scheduled to be launched in the summer of 1987, will be used in experiments on mobile satellite services performed to study basic technology for future integrated mobile satellite systems through the Experimental Mobile Satellite System (EMSS) at L-band frequencies (1. 6/1. 5 GHz). A description is given of the various kinds of land mobile earth stations used in the experiments. The gain-to-noise temperature and effective isotropic radiated power of these earth stations range from minus 20 dBK to minus 18 dBK and from 6 dBW to 20 dBW, respectively. Automobile earth stations with voice or data terminals, use alternate-channel single sideband and 2. 4 kb/s binary phase-shift keying-single sideband multiaccess as the modulation technique. A handheld earth station is used as a bidirectional low-speed terminal uses 100 b/s digital FM (continuous-phase frequency-shift keyed).
