Simulation solutions for space-based PNT

Lisa Valencia is a Project Manager and Senior Systems Engineer with a 30-year career at NASA. She is currently providing subject matter expertise to the Space Communications and Navigation (SCaN) Program Office at NASA Headquarters

Test Partner to Space Agencies & Industry

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.

Spirent Federal Systems is collaborating with Xona Space Systems to develop simulation and test capabilities for Xona signals produced by small satellites (smallsats) operating in low Earth orbit (LEO). Learn more.

The space and sector benefits from Spirent Federal’s expertise in generating high fidelity RF signals using quadrature (I/Q) data. Spirent test tools allow the full customization of I/Q data. Customers can generate unique I/Q data corresponding to experimental modulation schemes and use Spirent Federal’s signal generation capabilities to create the corresponding RF.

PNT testing for low earth orbit constellations

LEO constellations

Spirent’s precision, LEO-specific orbital models enable realistic design of LEO constellations. Together with flexible non-GNSS signal generation, this allows research and development into alternative PNT technologies using different signals of opportunity. View the GNSS Testing for LEO brochure.

Introducing SimORBIT

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.

Testing space vehicles

Space operations rely on robust PNT. Spirent simulations enable comprehensive scenarios to be tested encompassing launch and orbit insertion, and in-orbit operations, monitoring and control. Capabilities include ultra-high dynamics, proven realistic recreation of environments, and ultra-low latency hardware-in-the-loop testing for GNSS/inertial navigation.

Testing space applications

Spirent test solutions support space applications such as earth observation, communications, reflectometry, imagery and mapping, defense and security, and timing. Proven performance in evaluating devices helps to ensure the greatest mission success. Find out how Spirent supported Astrocast IOT connectivity.
