Tracking, Telemetry & Control

50+ Years Of Space Communications Success

General Dynamics has over 50 years of experience designing and manufacturing high reliability space electronics for NASA and the Department of Defense. We supply the tracking, telemetry and control (TT&C), precision navigation and timing, and crosslink equipment for missions of human space flight, near-Earth observation, lunar and deep space exploration.

Small Deep Space Transponder

The Small Deep Space Transponder (SDST), developed by General Dynamics and NASA's Jet Propulsion Laboratory, is a spacecraft terminal for X-Band and Ka-Band telecommunications with the NASA Deep Space Network. The transponder is currently in service on NASA's MAVEN Mission.

Multi-Mode Standard Transponder

The Multi-Mode Standard Transponder provides compatibility with a variety of government and commercial telemetry and command formats in a single unit at an affordable price. Available receive modes include NASA’s Tracking and Data Relay Satellite System (TDRSS), NASA’s traditional STDN ground network format, AFSCN SGLS and Unified S-Band, and a direct carrier BPSK mode compatible with commercial services and the NASA Ground Network (GN).

Space Ground Link System TT&C Transponder

General Dynamics’ Space Ground Link System (SGLS) Tracking, Telemetry and Command (TT&C) Transponder provides compatibility with the Air Force Space Control Network (AFSCN) SGLS telemetry and command formats in a single, highly reliable unit.
