KU-BAND COMMUNICATION SUBSYSTEMJarett, Keith; Hughes Aircraft Company (International Foundation for Telemetering, 1982-09)The Ku-Band subsystem for NASA’s Space Shuttle Orbiter is a combined radar and communications system that provides either radar-aided rendezvous capability or high-rate two-way communications via a synchronous-orbit TDRS relay satellite. This paper describes the architecture of the Ku-Band system and focuses on several unique aspects of the design. Communication capabilities are described in detail.
THE SPACE SHUTTLE ORBITER’S KU-BAND RADAR SUBSYSTEMShingledecker, D. K.; Hughes Aircraft Company (International Foundation for Telemetering, 1982-09)The Space Shuttle Orbiter’s Ku-band integrated radar and communications subsystem will function in its radar role during satellite rendezvous. As a radar the Ku-band subsystem searches for, acquires, and then tracks targets. In the track mode, the radar outputs measured range, range-rate, angle, and angle-rate values to both the Orbiter’s general purpose computer (GPC) and the astronaut’s Ku-band subsystem control panel. This data is used to navigate the Orbiter to its satellite rendezvous. The radar is integrated with the Ku-band communications function and thus achieves reduction in weight and volume compared with separate subsystems for each function. This paper provides a user oriented description of the radar subsystem. Topics to be covered are radar requirements, modes of operation, and system configuration.
