More Product Information

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.

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 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 D19-GT/-GTS Download Station ensures a secure and high-speed data download (via 40 Gbit Ethernet) from MDR or MDR-GT/-GTS storage media. Specifically designed for flight testing applications with demanding data rates and storage needs, the D19-GTS, when paired with MDR-GTS, incorporates advanced cybersecurity features like Data-At-Rest (DAR) protection and firmware updates. Configuration changes are facilitated through a Removable Secure Operational Disk (RSOD).

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.

Configuring, managing, and integrating the system are crucial steps for ensuring the success of flight testing and achieving precise telemetry. eZ Software is your go-to solution.
- eZ SetUp software allows to configure from a single acquisition unit to a complete acquisition system within a network architecture.
- eZ Operation software is an advanced tool for centralized supervision and control of complex test systems from an onboard operator station.
- eZ Processing / Advantys software offers advanced functions for data display and processing.

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.
