SECS ( Special Experimental Communication System , also TERCEL or GLOMR 2 ) was the improved further development of the US military communication satellite GLOMR. It was used for communication tests.
construction
The structure of SECS hardly differs from its predecessor. The satellite is also a 62-sided, 60 cm tall, but now 68 kg heavy polyhedron without stabilization. The main components are the transmitter, receiver, batteries and an associated battery management system. Compared to GLOMR, the system had improved digital storage and greater redundancy . The energy supply was also secured by solar cells attached to the satellite shell.
history
The launch took place on April 5, 1990 at 19:19 UTC with Pegsat on board the maiden flight of the first Pegasus from Edwards Air Force Base near Los Angeles. After the rocket was dropped from a Boeing B-52 , it carried the payload into orbit. The satellite remained in operation for 3.5 years.
