The Global Mobile Satellite System (GMSS) consists of several satellite phone providers serving private customers. It can be compared to PLMN (wireless telephony carriers) and PSTN (traditional wire-based telephony). As of 2023, ranges of numbers have been assigned to two GMSS carriers: Iridium Satellite LLC; Globalstar
A high-throughput satellite (HTS) is a communications satellite which provides more throughput than a classic fixed service satellite (FSS). An HTS provides at least twice, though usually 20 times or more, [ 1 ] throughput for the same amount of allocated orbital spectrum , thus significantly reducing cost-per-bit. [ 2 ]
