“Big LEO” Mobile-Satellite Services
CC Docket No. 92-166; IB Docket No. 02-364

The Big LEO mobile-satellite service (MSS) provides for the use of non-geostationary satellite systems that subscribers equipped with mobile earth terminal transceivers can use to conduct two-way voice and data communications with similarly-equipped subscribers or telephone users anywhere else in the world.  The Commission’s rules specify that the 1610-1626.5 MHz and 2483.5-2500 MHz bands are to be used for transmissions between Big LEO satellites and mobile earth terminals.
