Safran DSI - CORTEX BEST SOURCE SELECTOR Select the Best Telemetry Source in Real-Time
The CORTEX Best Source Selector (BSS) is the ultimate choice for real-time telemetry source selection. It’s the go-to tool for pinpointing the best Telemetry source among multiple antennas tracking the same airframe across various channels.
The Best Source Selector streamlines the selection process by automatically choosing the top Telemetry stream, even from up to 16 sources or more, using a combination of signal quality metrics and other criteria. With its extensive capabilities in aligning paths and compensating for delays, the CORTEX Best Source Selector ensures optimal source selection, no matter where the antennas are located or what kind of range infrastructure you’re working with.

More Product Information

The SPARTE 500 series, commonly mounted with a 4.4 reflector, is a top-of-the-line dual-axis antenna that spans dish sizes from 15 to 18 feet. This field-proven telemetry tracking antenna has been trusted by customers for their most mission-critical applications.
With a widespread presence on test ranges around the world, the SPARTE 500 series antennas excel in meeting the rigorous demands of various flight test scenarios, whether it’s for long-range aircraft, missiles or launch vehicles tests.
These antennas offer a streamlined design, ensuring easy operation and making them a perfect fit for any ground test range, working hand in hand with smaller range trackers.

The MDR system is your key to data collection in challenging, real-world airborne flight test scenarios. Its modular design allows it to seamlessly adapt to the full spectrum of test requirements, whether it’s a lightweight task or an extensive mission with diverse signals, environmental challenges, and lengthy recording periods.
A comprehensive range of signal interface modules, custom-tailored for various data sources and bus types, ensures that it’s ready to meet today’s demands and future requirements.

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.

Sensors acquisition and recording for troubleshooting is a cumbersome process in a fully furnished or operational aircraft, especially when time and low footprint are key drivers.
This is no more the case with Safran new solution µMA:
- its cylindrical form factor allows easy installation by just requiring a standard clamp used to mount tubes
- its battery power supply and its wireless connectivity removes the need of installing any harness in the aircraft.
All these capabilities are available while providing high measuring performance and harsh environment ruggedized in line with Safran standard solutions.

The MDR-GT / GTS is the ultra-fast on-board flight test (16 Gbps) instrumentation solution. The MDR family is technically based on a common mainframe with many high-end built-in interfaces and functions. The MDR-GT / GTS is highly customizable: functions and requirements can be addressed by adding dedicated interface modules, offering a variety of configuration options for all applications and requirements (MDR modules compatibility).
