FM Telemetry transmitter


AA SYSTEL integrates and represents exclusively on-board telemetry transmitters, receivers and amplifiers of VITEM company. VITEM is one of the leaders in these fields.

The main customers of VITEM: Dassault Aviation, Eurocopter (helicopter), French Flight test centers, Chinese Flight test centers.

The VTX 5000 NT/WT series telemetry / video transmitter is built around a state of the art Phase locked loop FM exciter followed by a high efficiency power amplifier. Working in L, or S -Bands, the VTX 5000 NT/WT series transmitter offers a very wideband frequency response from 1 Hz to 40 MHz which permits High Bit Rate (up to 32 Mbps) or color HD video-data transmission. The used technology allows the unit to operate under the environments as found in aircraft applications.

Airborne amplifiers



Intended for use with the VTX 5000 series transmitters,the VTA 5000 series power amplifiers are built around an efficient input RF limiter followed by a high efficiency class C amplifier chain, the spurious purity of which is given by an output RF filter.

The VTX 5000 series transmitter delivers 20W (or 10W) constant output power whatever the output level between 17dBm (50mW) and 36dBm (4W).

Airborne receivers



Designed to demodulate information laying in DC-12 MHz range contained on a± 4 MHz (up to 8 MHz) deviated FM carrier, the VTR 5585 WT is a simple conversion super-heterodyne unit using a synthesized local oscillator to convert the incoming carrier into a 550 MHz IF. The IF signal is filtered to be fed into the baseband processor.

The processor feeds the IF modulated signal into a hard-limiter before to be demodulated by a delay line demodulator.


Airborne antenna

AA SYSTEL integrates and represents exclusively airborne/ on-ground antenna of HYPTRA company. HYPTRA positioned as a key supplier on the commercial and military French markets, HYPTRA designs and manufacutures a full line of turn-key antenna systems including all individual equipment such as: Ground tracking station/ Pedestals/ Controller/ Tracking receiver/ radomes/ RF subsystem.

The main customers of HYPTRA: Airbus, Dassault Aviation, CNES, Alcatel, THALES, SAGEM, French Flight test centers, Chinese Flight test centers.

Airborne/on-ground Omni-directional antenna

HYPTRA designed a range of antennas using circular polarization with omni-directional azimuth pattern in the S frequency band. The marine aluminium antenna base allows to fix the aerial on a mast or on board aerial targets. The aerial is designed for harsh environments: -40°C to + 85°C operating temperature, seawater resistant.

In option,when used in reception, the antenna can be equipped with filter and LNA.
