L3Harris shipped a 12-meter folded rib reflector to Airbus in Toulouse, France for integration into the Biomass satellite.
Requtech designed the RESA L Ka terminal by leveraging its GEO/MEO reflector system PICO 120a and its RESA M Ku multi-orbit GEO/LEO terminal.
The NISAR spacecraft reflector is an antenna that measures 12 m across when fully deployed.
Thales Alenia Space will develop a Large Deployable Reflector (LDR) antenna enabling the I-MIM orbiter to establish high-data-rate communications with ground stations in Ka-band and X-band.
The Large Deployable Reflector (LDR) antenna on I-MIM will also serve the mission’s SAR instrument operating in L-band.
JPL is providing NISAR’s radar reflector antenna, deployable boom, high-rate communication subsystem for science data, GPS receivers, a solid-state recorder, and the payload data subsystem.
Parabolic reflector antennas offer high gain but can be slow, cumbersome, and prone to mechanical failure when operating on LEO or MEO satellites.
The phased array antenna in the MONDO design is utilized as the feed for the parabolic reflector when operating on a GEO satellite and as a standalone antenna when operating on a LEO or MEO satellite.
L3Harris deployed Jupiter-3’s four large reflector antennas on 2023-11-20.
The ViaSat-3 Americas reflector uses a wire mesh that is highly reflective at Ka-band frequencies and is supported by a structure of carbon fibers and graphite.
The boom connecting the ViaSat-3 Americas reflector to the spacecraft is a larger version of structures used to deploy the James Webb Space Telescope sunshield.
Viasat suggested it may wait until its quarterly earnings call scheduled for 2023-08-09 to provide further updates on the reflector.
Viasat announced the unexpected reflector deployment event on 2023-07-12.
Industry participants expect that failure to deploy the ViaSat-3 Americas reflector could lead Viasat to file an insurance claim worth as much as $420,000,000.
A corner reflector was added to the Delta second stage to enhance its radar signature for the test.
Oxford Space Systems’ Wrapped Rib antennas deploy carbon-fibre ribs from a central hub to form a 3-meter-diameter parabolic dish supporting a metal mesh reflector surface.
Oxford Space Systems established a metal mesh manufacturing facility at the Harwell Science and Innovation Campus to manufacture foldable reflector surfaces.
The Wrapped Rib Antenna supports a metal mesh reflector surface to provide a high-performing SAR reflector.
The medium-gain antenna operates in the X and Ka bands with a main reflector diameter of 0.5 meters and thickness of 0.7 millimeters.
L3Harris Technologies has a contract from Maxar Technologies to design and build reflector antennas for two geostationary communication satellites.
