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.

Safran’s SEEING™ 130 Wide includes a unique medium focal length catadioptric optics, limited by diffraction only and with ultra-low distortion, offering perfect imaging over 35 mm full-frame image format. It is fitted with a 10megapixel sensor.
SEEING™ 130 Wide enables high Signal to Noise Ratio for multispectral (MS), hyperspectral (HS) and low light level imaging. SEEING™ 130 Wide includes a spectral filter with 23 bands covering Blue, Green, Red, Near InfraRed and Red Edge MS, for a broad spectral range between 475 and 900nm. SEEING™ 130 Wide has a large Field of View of 6.3° x 4.3° / 54 x 36 km2 from a 500km/310 miles orbit.
In addition to its a thermal design within a robust structure, SEEING™ 130 Wide has a low SWaP, saving launch and operational costs.

The B.SAFE is a crash-survivable flight data recording for board defense aviation aircraft and helicopters.
B.SAFE is designed to capture audio, video, and data on a Crash Survivable Memory stored in a rugged and highly compact chassis. You can easily replay the recorded data in a standard PC/Windows® environment using post-mission analysis software.

Safran Ground Station is a turnkey ground segment solution with all required equipment and ground tools to proceed with removable media preparation and post-mission data retrieval and replay.
Key components are:
- Rugged Heavy duty Laptop PC for military environment
- RMM (Removable Memory Module) Docking Stations capable of reading up to 4 cartridges simultaneously, especially useful for mass debriefing.
- Ground software suite (RMM Manager, eZ Viewer, MUST), very intuitive and user-friendly interface, for replay and exploitation of data while allowing customizable configuration of the display for mission debriefing.
- Ruggedized Trolley Suitcase specifically adapted for the transport of the whole Ground Station.
This ground station, tested and approved by Safran before delivery, helps to accelerate the deployment on every integration Labs, Air Bases, and can be safely transported between different locations and environments

The SPARTE 700 series is a top-tier dual-axis antenna that boasts dish sizes ranging from 20 to 24 feet.
