COMTRACK stands as the preferred choice for over 100 trusted telemetry tracking operators.
Its track record spans various applications, from military aircraft and helicopters to commercial aircraft and even launch vehicles. COMTRACK steps in where larger, space-consuming parabolic systems may not be the best fit.
With its compact, rugged design, this embedded phased array auto-tracking antenna excels at providing reliable telemetry reception across L, S, or C-bands, covering the entire sky up to 93 miles away. Its intelligent integration combines high-elevation reception with long-range capabilities, all within a protective radome.
Additionally, it enables dual-band installations to support systems operating in both current and future frequency ranges. When it comes to trust, simplicity, and performance, COMTRACK takes the lead.

The RMM Manager utility software offers convenient, user-friendly pre-mission or post-mission access to SC1450-series Removable Memory Modules (RMM) for use with VS-Series video & data recorder/server, in PC/Windows® environment.

The SPARTE e100 is a hybrid antenna addressing the telemetry applications in S-Band, including hypersonic test articles.
The antenna is a combination of an Electronic Beam Steering supporting any elevation from -5° up to +95° and a single-axis mechanical rotation of the patch panel providing unlimited azimuth. The patch panel’s size enables the SPARTE e100 to achieve telemetry reception performance comparable to that of a 1.2m diameter dual-axis antenna.
This is achieved with a significantly simpler mechanical design, ensuring easier maintenance throughout the antenna’s operational lifespan.
The SPARTE e100’s rapid tracking capabilities, reaching speeds of up to 60°/s in azimuth and virtually infinite in elevation, make it an ideal “lock-on” antenna.

The CORTEX RSR-RF (-40 or -200) stands as a digital recorder that plays a vital role in capturing and reproducing the RF analog signal received by the antenna before any processing occurs.
It’s an essential component in a Telemetry Station, ensuring the utmost availability of crucial data, particularly in cases where on-board recording is not feasible.
Data collected in-flight offers extensive post-processing flexibility. You can fine-tune various settings in the receiver, the bit synchronizer, and the decommutator to maximize the extraction of data, a feat achievable only with RF recording. Furthermore, it serves as an invaluable tool for test range qualification ahead of test flights.

The PPS®5000, produced by Safran Spacecraft Propulsion, is a Hall Effect Thruster purposely designed for “all-electric” satellites. It can operate in high-thrust or high specific impulse mode,and offers an operating lifespan of about 20,000 hours. This means it can handle orbital positioning and station-keeping duties for a wide range of telecom and navigation satellites, as well as exploration spacecraft. The PPS®5000 was fully qualified in 2021.

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.

Our patented miniaturized L/S/C Tri-Band Feed delivers top-notch performance and unmatched flexibility.
Equipped with a common L/S/C radiating front end, it’s complemented by a modular set of active RF modules, enabling simultaneous reception and tracking across various frequency bands. Its compact, lightweight design allows it to be mounted on any dishes ranging from 6 to 24 feet.
Available in single, dual, or tri-band configurations, this feed offers the best value for customers looking to meet current requirements while staying future-ready.
It’s also field-upgradable to add any missing bands with straightforward RF module additions, ensuring scalability while keeping costs in check.

The SPARTE 300 series antenna is a battle-tested product that has consistently delivered top-tier performance for mission-critical applications where reliable telemetry reception is paramount. This rugged antenna guarantees our customers the utmost precision, a long operational life, and straightforward maintenance.
The SPARTE 300 series opens up a world of possibilities for users, ranging from aircraft tracking and high-speed target monitoring to duplex datalinks with both receiving and transmitting capabilities.
Furthermore, the extensive and customizable input/output options empower users to operate multiple antennas in a coordinated, multi-site tracking setup. With all antennas, regardless of size, being effortlessly monitored, managed and controlled by using our TM Maestro software.

XONOS enabling high data volume downlink between satellite & ground station. It is our latest state-of-the-art qualified COTS based design perfectly adapted to NewSpace programs, where cost effectiveness, performances and reliability are success key factors.
