For over 35 years, Spirent has been chosen by NASA and other space agencies to provide leading edge test solutions. Spirent GNSS solutions and expertise will support testing of the GNSS receivers intended to be deployed in NASA’s Artemis program for lunar exploration. Read press release.
Establishing a sustainable presence on the Moon presents new challenges for PNT and requires a robust lunar navigation ecosystem. Spirent is uniquely ready to support lunar navigation projects now. Our flexible test solutions allow custom signal generation and experimentation for developing new lunar constellations. Because of the priority we place on innovation and partnering with other experts who understand and recreate space environments—such as SpacePNT—we currently have a SW solution, SimORBIT, that can provide the precise modeling needed for lunar-orbit applications. Read our new brochure, Enabling Lunar Navigation, to learn more.
SimORBIT is the first high-accuracy orbital modeling software solution developed specifically for Low Earth Orbit (LEO) satellite simulation. Created in partnership with spaceborne receiver developer SpacePNT, Spirent SimORBIT enables developers to calculate LEO orbits and their distinctive characteristics more precisely and realistically for GNSS/PNT testing. Read the SimORBIT Datasheet.
Non-GNSS sources of RF (radio frequency) are of interest in GPS-degraded or contested signal environments. These systems offer high receiver signal power (relative to GNSS) and a secure & resilient link to augment GNSS.
Launched August 2021, Spirent Federal’s first-to-market Alternative RF Navigation Simulator enables alternative PNT signal simulation concurrently with GNSS. Testing can be static or dynamic, with stationary, pedestrian and ground vehicle trajectories available. Contact us to discuss fielded configurations.
