More Product Information

The PPS®1350 Hall Effet plasma thruster draws on Safran’s long experience with electric propulsion. It is designed for orbital transfer, station keeping and deorbiting satellites and other spacecraft. In particular, the PPS 1350 was the primary engine on ESA’s lunar probe, Smart-1, launched in 2003 by an Ariane 5 rocket. This mission was completed in September 2006.

The SafeLaunch-FTR is based on more than 20 years of skills and experience. Such Flight Termination Receivers equip air to air, ground to air and air to ground missiles as well as UAV, target drones and Launch Vehicles. They are qualified under MIL-STD-810F and MIL-STD-461E standards, and comply to RCC-319. The compact and optimized package is consistent in size and weight with the most severe requirements of missile platforms. The electronical design, based on the latest generation of Software Defined Radio (SDR) components, brings to SafeLaunch-FTR high reliabilty and evolutivity.

The VS1510 is a video & data recorder/server packaged in a rugged compact chassis (4.92” x 5.75” x 7.28 ” / 9.9 lb), for recording on a Removable Memory Module (RMM).
Recorded data can be replayed in a standard PC/Windows® environment, using specific or COTS mission debrief solutions for post mission analysis.
In addition, typically for ISR applications, data can be replayed while recording on board. The ENERTEC™ mission data processing and distribution units offer cost-effective and dependable solutions for collecting, processing, storing, utilizing, and sharing field and mission data.
These units are designed for both manned and unmanned ground, air, and sea vehicles. They undergo rigorous validation and formal qualification testing, conforming to established standards such as DO-160 and MIL-STD-810.

The RTR-X4 is one of the most advanced digital telemetry receivers on the market with its well-recognized RF performance and signal processing capability.
The 4U chassis-based RTR-X4 can support up to four channels providing flexibility and capability as well as a rich set of features for different frequency bands, modulations, decoders and output formats.
Not only does the CORTEX RTR provide an extensive set of features for different frequency bands, modulations, decoders and output formats, but the user can easily upgrade the equipment in the field to access additional and new features. The RTR-X4 is an excellent fit for flight test ranges, offering full flexibility and easy access to settings through its user-friendly GUI on the embedded 8.4-inch screen.
