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.

The VS1410 is a video & data recorder/server packaged in a rugged compact chassis (3.75” x 5.75” x 7.36” / 6.4 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 acquiring, processing, storing, exploiting, and disseminating field and mission data.
These units are suitable for both manned and unmanned ground, air, and sea vehicles. They undergo rigorous validation and formal qualification testing, adhering to standard test methods such as DO-160 and MIL-STD-810.

The PPS®X00 plasma thruster (Hall effect) takes benefit of Safran’s long experience with electric propulsion to propose a very efficient product. PPS®X00 was designed to address the specific requirements inherent in the “New Space” market environment. With a lifespan exceeding 5,000 hours and very high specific impulse, the PPS®X00 is an extremely versatile thruster, making it ideal for all types of applications in its core market: low Earth orbit (LEO).

The CORTEX NuRoN Software Modem is the all-in-one satellite support solution, covering every step from check-out to in-orbit operations.

Operating on standard x86 servers, NuRoN is fully compatible with both private and public cloud setups, offering unprecedented flexibility and scalability as your company expands.
Built on the rock-solid foundation of the industry-standard CORTEX legacy, NuRoN is the hassle-free, secure, and easily deployable software modem for all your Command & Control needs.

The SPARTE 1300 series antenna is a tried-and-tested solution designed for mission-critical applications where reliable telemetry reception is essential. This antenna excels at accurately tracking flying targets, such as aircraft or space launch vehicles, even over long distances, thanks to its high-gain, large-aperture design.
Built with a robust and sturdy construction, the SPARTE 1300 series guarantees optimal performance in any scenario. It features an aluminum-alloy reflector for enhanced surface accuracy, SCM tracking feeds for dependable and precise tracking, and quad-drive motors for redundancy and no-backlash operation.

The highly flexible modular GMDR system is a versatile and future-proof solution for acquisition, recording, dissemination and replay of FTI data in ground station applications.
With its high integration, incomparable range of supported video interfaces and full compatibility with global leading MDR products, the GMDR integrates seamlessly into customers‘ existing test range topologies.
With its intelligent data reduction through segmentation, pre-selection and filtering as well as the capability to freely disseminate subsets of data among several network destinations, GMDR efficiently reduces the operator‘s workload when analyzing test results.
For standard PCM/Ch7-Telemetry applications, two simplified, cost-efficient variants with integrated PCM/Ch7-Telemetry signal boards and one Data Express technology (DE50)- compatible storage media slot are available.

eZ Processing is the solution for telemetry data processing, analysis and display (real time or playback). It allows the capture of the data either from a PCM signal or directly through data sent on Ethernet (IRIG 106 Chapter 10) by the receiver.
It performs the frame synchronization, Engineering Unit conversion, data display and storage, as well as data subset dissemination to dedicated analysis tools. It can accommodate multiple display stations, each having selectable parameters and displays. When used in a system with Safran Defense & Space, Inc. (formerly Safran Data Systems, Inc.) data acquisition units like the XMA or MDR, the software parameter database is automatically updated by eZ configuration software, reducing the set-up time and preventing all errors.
