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.

AN INTELLIGENT EYE

ELECTRONICALLY SCANNED ANTENNAS (AESA)

Electronically scanned antennas have evolved from simple observation systems into intelligent guides, enabling the precise tracking of objects in flight, be they satellites, aircraft or drones. Their versatility makes them key elements in navigation, communication and surveillance.

For example, these antennas are revolutionizing the performance of radar systems. Integrated into modern fighter aircraft programs such as the Eurofighter Typhoon and Rafale, they enable efficient tracking of moving targets, thanks to improved directivity, high pointing speeds and dynamic adjustment of the number of beams.

AUTOMATIC AUTOTRACK

The electronics in these antennas make them exceptionally agile, enabling them to track targets quickly and accurately, without any mechanical movement. Thanks to "autotrack" technology, the antenna constantly seeks the maximum signal level from the object to be tracked, adjusting its direction in real time to maintain optimum reception. This communication opens the way to a multitude of actions: supervision, trajectory adjustment, performance optimization and anticipation of potential failures.
