The Space Force is exploring options for expanding the capabilities of its GPS satellites and is asking companies to propose ideas for delivering low-cost demonstration spacecraft to help test new technologies.
Space Systems Command, the service’s primary acquisition organization, said in a Feb. 5 notice it is conducting market research to refine its concept for a constellation of GPS demonstration satellites. The government is studying ways to reduce lifecycle cost and increase the pace of GPS satellite development, production and on-orbit deployment.
The service has around 31 operational GPS satellites in orbit, a mix of modern and older spacecraft providing varying levels of capability. The newest satellites, dubbed GPS III, are built by Lockheed Martin and provide three times greater accuracy and much-improved anti-jamming abilities than previous variants. Lockheed is also developing the next iteration of space vehicles, GPS IIIF, which will build on the accuracy and anti-jam protections of the GPS III satellites.
The Space Force has been considering how it can augment them with alternative systems, including smaller satellites that are cheaper, easier to produce and able to operate in degraded areas where GPS isn’t accessible today. A constellation of demonstration satellites could help the service validate and quickly field new augmentation capabilities or inform upgrade plans for future GPS satellites. Once launched, NTS-3 will conduct more than 100 experiments testing different technology, including a digital signal generator that can be reprogrammed in orbit to broadcast new signals.
The Space Force’s Commercial Space Office is also working with its innovation arm, SpaceWERX, to identify alternative navigation capabilities. Col. Richard Kniseley, senior materiel leader for the office, told C4ISRNET the goal of that effort is to provide seed funding for non-traditional companies to mature capabilities.
