International Telemetering Conference Proceedings / October 28-31, 1996 / Town and Country Hotel and Convention Center, San Diego, California / An S-band telemetry transmitter has been developed for Expendable Launch Vehicles
(ELV's) that can downlink data through NASA's Tracking and Data Relay Satellite System
(TDRSS). The transmitter operates in the 2200 to 2300 MHz range and provides a number
of unique features to achieve optimum performance in the launch vehicle environment:
· Commandable QPSK or BPSK modulation format.
· Data rates up to 10 Mbps.
· Commandable concatenated coding provides superior link performance.
· Premodulation filtering produces excellent spectral containment characteristics.
· Phase noise of less than 3 degrees rms is maintained through launch and ascent
vibration profiles.
· A 30 watt nominal RF output power provides a robust RF link.
· Two RF antenna output ports with commandable selection of all power out to either
port or power split evenly between ports.
· Operating modes and conditions of the unit can be monitored through a number of
bilevel and analog outputs.
· A ruggedized mechanical design provides a reliable communications link for launch
vehicle environments.
