Comtech Telecommunications has been granted $20m in funding to support the US Army's Blue Force Tracking (BFT-1) programme.
BFT-1 systems locate friendly military forces, and can also send and receive text and image messages.
Funding was provided as part of a three-year BFT-1 sustainment contract and related intellectual property licence agreement.
Nearly 50% of the funding will be used to license parts of the company's BFT-1 intellectual property, while the remainder is allocated for engineering services and satellite network operations.
Comtech Telecommunications president and CEO Dr. Stanton Sloane said: "We are pleased that Comtech and the US Army will continue to work together to sustain this critical worldwide military communications system.
"The receipt of these contracts further demonstrates the ongoing importance of the US Army's BFT-1 satellite tracking communication system."
The company's sustainment contract and related BFT-1 intellectual property license agreement were first awarded in April 2014.
The deals with a combined not-to-exceed value of $71.2m have received close to $69.3m in total funding.
Comtech designs, develops, produces and markets innovative products, systems and services for advanced communications solutions.
The company serves a diverse customer base in the global commercial and government communications markets.
