Unfurlable Mesh Antenna Reflectors Successfully Deployed in Space with DoD's MUOS Satellite

  • Harris antenna reflectors are part of Ultra High Frequency (UHF) communications satellite developed by Lockheed Martin that launched February 24 onboard Atlas V rocket.
  • Antenna reflectors will significantly increases the number of users and traffic the system can support.
  • Harris is the world leader in space-borne, unfurlable mesh antenna reflectors.

Two unfurlable mesh antenna reflectors developed by Harris Corporation (NYSE:HRS) were successfully deployed last month onboard the first Mobile User Objective System (MUOS) satellite built by Lockheed Martin Space Systems Company, Sunnyvale, California. MUOS will provide military users with next-generation, narrowband tactical satellite communications with 16 times more capability than existing UHF satellites, including superior data rates and priority-based access to on-demand voice, video and data transfers. The announcement was made during the National Space Symposium being held April 16-18 at the Broadmoor Resort in Colorado Springs, Colorado.

The MUOS satellite, developed for the U.S. Navy, leverages the latest commercial advances in cellular and satellite technology, while maintaining compatibility with legacy UHF systems. This is the first of five MUOS satellites scheduled for deployment.

Each MUOS satellite will carry two Harris antenna reflectors — a 14-meter diameter unit for multiple-beam operation that significantly increases the number of users and traffic the system can support and a 5.4-meter diameter unit for legacy mission operations. The reflectors are secured to the satellite by precision booms that are also provided by Harris. A reflective gold mesh weave provides the reflective surface required for radio waves. In total, Harris is building ten units for the MUOS constellation, with the remaining eight units in varying stages of production.

"We are working closely with Lockheed Martin and the Navy's Communications Satellite Program Office as the first MUOS satellite begins operation," said Sheldon Fox, group president, Harris Government Communications Systems. "These antenna reflectors embody our commitment to placing the most advanced communications technology in the hands of our warfighters."
