Two advanced satellite systems (SAFIR and INMARSAT) are described. SAFIR (SAtellite For Information Relay) in low earth orbit is a program using small satellites for a two-way environmental data collection, distribution, and tracking. SAFIR aims at a non-real-time exchange of data and messages between objects (birds), equipped with very small and inexpensive microstations, and users (scientists), equipped with small macrostations. Both stations operate at UHF frequency bands. Two methods of position determination are implemented, one with an accuracy of <1000 m and a second with an accuracy of <100 m. A small constellation of SAFIR satellites (2–6) will be deployed in different orbits providing the store and forward service. In the first phase, SAFIR-R as attached pay load was launched in May 1994 into a 700-km, sun-synchronous polar orbit. During the first 3 months, link and frequency tests under various ground conditions were performed. Additionally, the communication concept, routing, and user data management were evaluated and verified. The SAFIR user terminals have already been delivered to selected users (anchored buoys, subsurface buoys, tracking of migrating animals, antarctic stations, and container tracking). The geostationary communication system is based on the existing ET-1600 INMARSAT EPIRB satellite-based distress alerting system and consists of a transmitter, a micro—tracker, and an antenna. The prototype weighs approximately 200 g. The miniaturization of this terminal will enable wide application areas, including real-time tracking of migrating birds.
