Project background<\/h3>\n

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.<\/p>\n

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.
\nPreviously 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 In order to avoid wasting time and money designing and realizing these elements, they have been replaced by hexapods.[\/vc_column_text][\/vc_column_inner][\/vc_row_inner][image_with_animation image_url=”5601″ animation=”Fade In” hover_animation=”none” alignment=”center” img_link_large=”yes” border_radius=”none” box_shadow=”none” image_loading=”default” max_width=”100%” max_width_mobile=”default”][divider line_type=”No Line” custom_height=”10″][vc_gallery type=”image_grid” images=”36499,36502,36504″ layout=”3″ item_spacing=”default” gallery_style=”1″ load_in_animation=”none” img_size=”193×95″][\/vc_column][vc_column column_padding=”no-extra-padding” column_padding_tablet=”inherit” column_padding_phone=”inherit” column_padding_position=”all” background_color_opacity=”1″ background_hover_color_opacity=”1″ column_shadow=”none” column_border_radius=”none” column_link_target=”_self” gradient_direction=”left_to_right” overlay_strength=”0.3″ width=”2\/3″ tablet_width_inherit=”default” tablet_text_alignment=”default” phone_text_alignment=”default” column_border_width=”none” column_border_style=”solid” bg_image_animation=”none” enable_animation=”true” animation=”fade-in-from-bottom”][vc_column_text]\n

OUR EXPERIENCE AT YOUR SERVICE<\/h3>\n

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.<\/p>\n
