Description

The Space Ground Link Subsystem (SGLS) TT&C Transponder is a space-qualified, TOR-compliant, S-band transponder that provides compatibility with the Air Force Satellite Control Network (AFSCN) SGLS telemetry and command formats in a single, highly reliable unit. This transponder has been designed for the demands of space including missions in low Earth orbit (LEO), medium Earth orbit (MEO) and geosynchronous Earth orbit (GEO).

The Space Ground Link Subsystem (SGLS) TT&C Transponder operates at uplink command rates of 1 kbps and 2 kbps (automatically detected) and provides downlink telemetry data rates up to 32 kbps on a 1.7 MHz subcarrier. Coherent operation, including ranging, is selectable via command, as is rate 1/2, constraint length 7 convolutional encoding. For signal security the unit provides interfaces to the KG-327 cryptographic unit for uplink decryption and downlink encryption. Being fully compliant to Aerospace Parts, Materials and Processes TOR requirements results in lower life-cycle costs by reducing the probability of parts issues impacting spacecraft integration and test efforts.
