Harris has installed two unfurlable mesh antenna reflectors on-board the third Mobile User Objective System (MUOS) satellite of the US Navy.
Built by Lockheed Martin Space Systems, the MUOS module is designed to deliver improved and secure communications, including voice, video and data for troops on the move.
This new development marks the fifth and sixth successful Harris reflector deployments in the planned five-satellite MUOS system.
Harris government communications systems national programmes vice-president and general manager Bill Gattle said: "This third on-orbit deployment again demonstrates how the unique design and flexibility of our mesh reflectors is meeting the needs of the MUOS satellite programme.
"We remain committed to delivering the most advanced satellite communications technology to our warfighters."
Harris received orders to build ten reflectors for the MUOS constellation, two per satellite, with a 14m diameter unit for multiple-beam operation and a 5.4m diameter unit for legacy operations.
The company manufactured the reflectors at its advanced manufacturing facility in Palm Bay, Florida, US.
The US Navy's MUOS satellite constellation operates similar to a smartphone network in the sky, enhancing the current secure mobile satellite communications for troops.
It offers users and on-demand, beyond-line-of-sight capability to transmit and receive high-quality, prioritised voice and mission data, on a high-speed IP-based system.
The MUOS satellite network is expected to achieve full operational capability by 2016 and ensure the availability of UHF narrowband communications for the US Navy past 2025.
