Sierra Space Advances Resilient GPS Technology for U.S. Space Force
[Date] – [Location] – Sierra Space, a forefront leader in commercial space and defense technology, has successfully completed a pivotal demonstration of its Resilient GPS (R-GPS) technology aimed at bolstering the U.S. Space Force’s operational capability. This marks the third significant milestone in a program designed to enhance GPS infrastructure against increasing threats like jamming and spoofing.
During the recent demonstration, Sierra Space showcased the early integration of R-GPS satellite technology, employing FlatSat flight software and conducting vital hardware subsystem testing. Successful communication was established with ground software systems, affirming the technology’s efficacy between orbital and terrestrial operations.
The R-GPS initiative forms part of a larger effort by the U.S. Space Force’s Space Systems Command to develop smaller, cost-effective GPS satellites. In September 2024, Sierra Space secured a Quick Start contract to create design concepts for these innovative satellites, aiming to expedite the introduction of advanced technology into the national security space sector. Remarkably, this advancement occurs just six months after the program’s initiation, underscoring Sierra Space’s capacity to respond swiftly to evolving defense requirements.
As GPS technology plays an essential role in both civilian and military applications—from navigation on smartphones to critical defense operations—the urgency for resilient systems has intensified in the face of growing adversarial threats. The R-GPS program seeks to augment the existing GPS architecture with a network of smaller satellites, enhancing security and rapid deployment capabilities.
The latest testing milestone demonstrated effective command and telemetry flow between Sierra Space’s ground software and a ground station service provider, reinforcing the operational viability of this advanced technology. Utilizing the FlatSat testing format allowed for comprehensive evaluation of satellite components, facilitating early integration of essential flight software and hardware subsystems.
