Ground Telemetry Instrumentation

With 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

Schematic of a Complete 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.


Ground Telemetry - COMTRACK Telemetry Tracking Antenna

COMTRACK is an S- or L- or C-band auto tracking phase array antenna designed for telemetry applications, aircraft and helicopter flight tests, UAV datalink and surveillance solutions on fixed and mobile stations.

Ground Telemetry - SPARTE Telemetry Tracking Antenna

The SPARTE pedestal is a 2-axis tracking telemetry antenna which is widely used by testing organisations around the world. The antenna is robust, accurate and simple to maintain.

Ground Telemetry - Tri-band Antenna Feed

We offer the best match for performance, flexibility and price with this patented miniaturized tri-band feed (L/S/C).

Ground Telemetry - CORTEX Compact Telemetry Receiver (RX-1)

The Cortex RX-1 is a small-size dual channel telemetry receiver with pre-D combiner that covers all IRIG frequency bands and all IRIG-specified modulations.
