With the new SimORBIT high-accuracy orbital modeling software from Spirent, developers can now calculate LEO orbits and their characteristics for more precise GNSS/PNT testing.
The software, the first designed specifically for LEO satellite simulation, was created in partnership with spaceborne receiver developer SpacePNT, according to a news release.
Testing space-based applications in the field is difficult and cost prohibitive, making accurate lab testing critical. New LEO satellites demand highly accurate modeling to “provide the realism needed for high-value testing, including representing the distinct gravitational and atmospheric impact LEO satellites will endure in space.” With the SimORBIT model, developers can now accurately replicate LEO orbits. This enables customers to test using simulations that more closely resemble a LEO satellite’s true operating environment.
“Until now, PNT testing on LEO applications has been limited due to the lack of an integrated solution that could offer realistic LEO orbital data together with GNSS simulation capabilities,” said Adam Price, Spirent’s vice president of PNT Simulation, according to the release. “By working in close collaboration with SpacePNT, we have been able to develop the SimORBIT tool to bring a new level of accuracy and realism to LEO application testing by combining the simulation of precise LEO orbits and highly accurate GNSS signals.”
This complements the company’s simulation systems and their ability to generate non-ICD signals via I/Q injection, or by the Spirent “Flex” feature, enabling new space based PNT signals to be developed as realistically as possible in the lab.
“As a leader in LEO PNT technology, we at SpacePNT are always keen to partner with other industry market leaders such as Spirent for the testing of PNT technology,” CEO and Founder Cyril Botteron said, according to the release. “Spirent’s open and rich PNT simulation environment has made the collaboration seamless, and we are proud to offer such a new, innovative building block for this rapidly emerging key PNT technology.”
