Sierra Space has successfully tested its Resilient Global Positioning System (R-GPS) satellite, a key step in the US Space Force’s Quick Start program to strengthen GPS security.
The effort aims to deploy a fleet of small-form-factor satellites that will serve as a “layer” of protection against jamming and spoofing threats targeting American GPS infrastructures.
The activity validated the satellite’s capability to generate multiple frequencies and ensure that GPS-based navigation is “accurate, secure, and compatible” with devices on the ground.
“This milestone not only underscores our commitment to advancing GPS technology, but positions Sierra Space to be optioned for Phase One, the next step of the US Space Force’s Quick Start program,” Sierra Space Defense Vice President Erik Daehler remarked.
The demonstration was successfully facilitated in partnership with General Dynamics Mission Systems.
Progress in Quick Start Program
Sierra Space received the contract to produce a GPS satellite for the Quick Start program in September 2024.
The framework, awarded by the US Space Systems Command, ordered the design and assembly of a “smaller, more affordable” concept supporting “rapid response to emerging threats or technologies” and “swift” initiation of other space-based Department of Defense programs.
Later that year, the satellite passed an internal Systems Requirements Review that confirmed the solution’s build for space demonstration.
By 2028, Sierra and other contenders of the Quick Start program will finalize manufacturing of up to eight R-GPS payload prototypes.
It will be followed by the constellation’s launch in the same year, with one or more vendors to be selected for the construction of the satellite vehicles.
“Our country needs GPS satellites with more capability and resiliency at a faster rate, and we are proud to bring our mature, mission-ready and proven portfolio of capabilities to Sierra Space to help the US Space Force achieve these objectives quickly,” General Dynamics Space, Cyber & Intelligence Systems VP Amy Johnson stated.
