Spirent brings realistic testing to emerging LEO satellite applications

Spirent Communications plc has announced availability of SimORBIT, the first high-accuracy orbital modelling software solution specifically developed 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.

Testing space-based applications in the field is extremely difficult and cost prohibitive, which is why accurate lab testing is vital. The new era of LEO satellites demands highly accurate modelling of the Low Earth Orbit environment to provide the realism needed for high-value testing, including representing the distinct gravitational and atmospheric impact LEO satellites will endure in space. Using Spirent’s SimORBIT model, developers can now accurately replicate LEO orbits for the first time, enabling customers to test using simulations that more closely resemble the true operating environment of a LEO satellite.

This capability complements the ability of Spirent’s simulation systems to generate non-ICD signals via I/Q injection, or by the unique Spirent “Flex” feature, enabling new space based PNT signals to be developed in the lab as realistically as possible.

Spirent provides the most comprehensive and realistic GNSS test environments, working with leading PNT players to deliver the flexible, scalable, and future-proof architecture needed to evolve with technology. The SimORBIT orbital model highlights the company’s continued commitment to providing customers with the most realistic, most valuable
