Tracking and Data Relay Satellites

Links between LEO satellites (or the NASA Shuttle) and GEO satellites are used for data relay, for example, via the NASA tracking and data relay satellite system (TDRSS). Some systems wiU use intersateUite Unks (ISL) to improve the interconnectivity of a wide-area network. ISL systems would typically operate at frequencies such as 23 GHz, 60 GHz, or even use optical links. [Pg.1788]
