Ground Telemetry InstrumentationWith 45 years of experience in flight test instrumentation and telemetry solutions our partners at SAFRAN Data Systems design and build technology to meet the ever evolving needs in the aerospace industry, and that performs reliably in the most challenging environments including at sea, the artic, and the tropics.
A Complete Turnkey Ground Telemetry System
The complete end to end solution begins with a range of antennas, from compact portable units to those with reflectors from 1.8m to 7.3m in diameter, mono, dual, and tri band feeds. Each options comes with a modern, user friendly, Antenna Control Unit (ACU) to ensure the most accurate tracking and to deliver telemetry reception for mission-critical applications.
The above schematic illustrates the use of two antenna to receive telemetry from a far ranging aircraft; a COMTRACK mobile antenna typically used in the field, and larger Sparte dish antenna with tri-band feed typically fixed, though can be transportable or mounted on the deck of a ship. The RF output of the antenna is then converted into the required data stream (Analogue PCM / DQE-DQM / Ch10 / IRIG 218-20) by either the RX-1 or RTR high performance RF telemetry receivers. In addition, prudence may suggest recording the raw RF signal for replay in case something is missed. The RSR RF Recorder is ideal.
A Best Source Selector determines which of the two antenna and receiver pair is receiving the best quality telemetry and in turn feeds a PCM stream to the GMDR recorder, and a PCM Ch.4 or UDP Ch. 10 data stream to a PC running the eZ Processing software for near real time monitoring and the review of recorded data from the GMDR.
Where ever it is located, all hardware can be controlled using Safran's Maestro Misson Control Software. And it's all COTs, non ITAR.
