Sierra Space's R GPS program, launched last September, aims to design smaller, more cost-effective GPS satellites to enhance national security. GPS technology is essential for both military and civilian uses, but the emergence of sophisticated threats such as jamming and spoofing makes it necessary to develop more resilient systems.
The US Space Force's R GPS initiative aims to enhance the existing GPS architecture with a network of smaller, more secure satellites. In this test, Sierra Space validated the transmission of commands and telemetry data between its ground software and ground stations, demonstrating the ability of R GPS technology to operate effectively from space, in interaction with ground installations. Tests also covered hardware and software subsystems in FlatSat mode - an essential step in preparing for future space deployments.
Sierra Space, based in Colorado, has designed the Dream Chaser, a reusable, fully autonomous orbital aircraft designed to transport cargo to low-Earth orbit destinations. Measuring around a quarter the size of a space shuttle, it features autonomous launch, flight and landing capabilities. At the same time, the company is working on a manned version of the Dream Chaser. This future version will be used to join the Orbital Reef space station, a project currently under development with other companies in the sector, including Blue Origin and SpaceX. Valued at 5.3 billion dollars, the American company is also multiplying its partnerships, such as the one with Honda, to develop new energies in space.
