More Product Information

The N-SPHERE comes as a new generation of GNSS receiver. It implements the latest state-of-the-art positioning and synchronization techniques, to reach top class of performances for Real-Time Precise Onboard Orbit Determination (P2OD) and accurate time synchronization.

The Mobile Telemetry Rack (MTR) integrates state-of-the-art telemetry capabilities utilizing the RTR-X4 & GMDR recorder providing the ideal portable telemetry checkout system, able to receive demodulation, record, process and display your data throughout your system development.
Based on the Cortex architecture, the 4U chassis-based CORTEX RTR-X4 can support up to four channels providing the utmost flexibility and capability a Telemetry Receiver can achieve.
The GMDR Chapter 7 recorder fits particularly well for the flight test support where operability and flexibility is essential. Not only the does the Telemetry rack provide a rich set of features, the Dell Server comes with the standard Safran software tools you expect: D4 Recorder, C10 Extract, eZ Viewer Data Verification and Quick Look Software.
Additionally, multiple projects can be supported by just swapping out the OS & media drives in support of classified projects.

The SPARTE 900 series antenna stands as a testament to reliability and performance, tailored for mission-critical applications where telemetry reception is paramount. This field-proven product ensures accurate tracking of flying targets, such as aircraft or space launch vehicles, even at significant distances, thanks to its high gain and large aperture design.
The robust and durable construction of the SPARTE 900 series guarantees optimal performance in any scenario: an aluminum-alloy reflector for enhanced surface accuracy, SCM tracking feeds for dependable and precise tracking, and dual-drive motors for redundancy and no-backlash operation.
Additionally, the SPARTE 900 series comes equipped with a riser that integrates the Antenna Drive cabinet and any necessary equipment, allowing for optimal positioning in close proximity to the antenna.

The Mission Recorder Cockpit Remote Control Unit is mounted in a cockpit dashboard and connect to a recorder system. The MCRCR shows status information on the NVG compatible display and can remote control the Mission Recorder System.
The ENERTEC™ mission data processing and distribution units are dependable, cost-effective solutions designed to facilitate field and mission data handling, processing, storage, analysis, and distribution. These units are compatible with both manned and unmanned ground, air, and sea vehicles, offering a dependable resource.
