Harris has secured orders to support the US Army's modernisation of enterprise terminals (MET) programme.
Valued at $41m, the orders require the company to produce and install advanced satellite communications terminals for the US Army, Navy, Air Force, and Missile Defense and Defense Information Systems agencies.
Harris's fixed-site terminals and hardened transportable terminals provide dual X and Ka-band access to the new Wideband Global SATCOM (WGS) network as well as legacy satellite constellations.
The WGS satellites are based on the Boeing 702HP platform and designed to support simultaneous X and Ka band communications, allowing soldier to communicate across terminal types.
Harris electronic systems president Ed Zoiss said: "MET's state-of-the-art multiband terminals will provide critical communications and situational awareness capabilities for US decision-makers and military personnel deployed worldwide.
"Harris has supported the warfighter with high-performance, cost-effective military satellite communications capabilities for decades, and we are committed to continue this support through the MET programme."
Harris is the prime contractor for the MET indefinite delivery / indefinite quantity (IDIQ) contract, which was awarded in 2009.
The $800m contract has a five-year base period and a five-year option period.
The latest orders bring the total value of MET orders awarded to Harris to $516m.
In a separate development, the company received a five-year, $405m IDIQ contract from the US Army Communications-Electronics Command.
This contract will see the company deliver tactical communications equipment, including export versions of its single channel ground and airborne radio system (SINCGARS); ground and airborne configurations of the SpearNet Team Member radio; and training, installation, and field service support.
