Satellites antennas testing

Project background

The AIT (Assembly, Integration, and Tests) service of telecommunication satellite manufacturers tests the antennas’ performance inside anechoic chambers, in order to reproduce communications between the geostationary orbit and Earth stations.

During the satellite’s life, antennas can be reconfigured and reoriented to communicate with different stations. As the space mechanisms used to reorient the antennas cannot function at Earth gravity, they are replaced by hexapods during the RF tests.
Previously satellite manufacturers used more conventional systems made for each satellite. In order to avoid wasting time and money designing and realizing these elements, they have been replaced by hexapods.


Combined with our expertise in metrology, the hexapod technology is appropriate for antenna qualification because it allows very precise motions in the 6 degrees of freedom while bringing reconfiguration flexibility via software.

Project specifications

 Compatibility with RF environment
 Pivot point configuration in software to test different kinds of antennas for various
 Easy preparation of tests in software to adapt to configurations with 1 to 6 antennas
 Sirius hexapod is the most used for this application, even in customized versions for heavier payloads. Breva hexapod can also be used for lighter antennas or RF sources with smaller travel ranges.
