With 30 years of experience in Telemetry, NEXEYA has a strong expertise and capabilities in
Telemetry systems and data processing. NEXEYA now offers a broad set of advanced telemetry
solutions for a variety of military and aerospace applications including system integration and
validation, flight testing and operational missions.
MAGALI Telemetry Systems
“The Mobile Telemetry Centre” was developed by NEXEYA to meet customer expectations for a generic and high-
performance Telemetry Data Processing System to collect system under test health data, as close as possible to test
fields.
The mobile Centre offers extended capabilities for remote control, information distribution, data recording, processing
and display. It proposes different test modes (short and long distance, redundancy, autonomous...) for secure testing
and safety decisions.
Test configuration, real time monitoring, data analysis, visualization and sharing, test replay… all functions are
performed by our powerful and unique telemetry software MAGALI.

Mission Control Software
BSS
The BSS (Best source selection) builds the best source from several telemetry signals. This functionality is provided
when several antennas are dispatched all over the telemetry range. This ensures good reception of the target whatever
the mobile localization. Decision is made on baseband signal characteristics and on telemetry data frame contents. The
quality factors used for the treatment are user customizable and the number of sources is infinite. Post Processing BSS
can also be done to improve the best merged data.
The mission Control Software is designed to give an overall status of the complete system. Each component can be
remotely managed (Antenna, Receiver, Recorder, Simulator, RF generator, Telemetry Station...). Flight Test Engineers
can easily check all equipment status and proceed to the pre-check flight test to verify the complete installation.

Antenna Tracking
Antenna Tracking is available for wide range test installation using several antennas. This function tracks the target
(direction, location, …) and correctly aligns the directional antenna even when the signal is lost. By this way, slave
antennas are correctly aligned when the signal is strong enough to auto track the signal.
Different modes of tracking are available :
Auto tracking (to track the maximum power of the source)
Antenna trajectory extrapolation (in case of loss of signal)
GPS tracking
Programmed tracking
Manual Mode (using a joystick)
Trajectory Station is provided to display the status of all the antennas positioning regarding the mobile situation. LOS
and AOS of the antennas & mobile are drawn to expect when the antennas can be autotrack or not.
