For over 35 years, Spirent has been chosen by NASA and other space companies 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.
Low Earth Orbit (LEO) satellite constellations are already offering a multitude of benefits, from communications to earth imaging and disaster detection and mitigation. The next generations of LEO constellations will deliver specialized positioning, navigation and timing services to users around the world, high-speed wireless data connections, and open up new opportunities for restricted communications technology. With these great opportunities comes a range of challenges. Spirent solutions are designed to meet the stringent requirements of next-generation technologies, and are perfectly placed to enable your LEO project.
