The Space Force, the military branch responsible for providing satellite-based services to the U.S. armed forces, was also recently assigned the role of “integrator for joint space requirements,” which means the Space Force will have to coordinate the wish lists of the Army, Navy, Marine Corps and Air Force, and recommend how to meet future needs.
The bulk of those needs will come from the U.S. Army’s land forces, which are large consumers of satellite services for global navigation and communications. Army forces also have a growing appetite for new space services that provide alternatives to GPS navigation and imagery from low orbiting satellites that revisit the same spot multiple times a day.
Communications and tactical data however are pretty much the same no matter which service needs them. The biggest issue the military faces isn't in a standard for the satellites, it's replacing all the terminals in a variety of gear of various ages.
