GNSS Testing for When the Sky Is Not Your Limit

Our GNSS simulation software, SatGen, is not limited to the standard GNSS receiver restrictions of 1000 knots and/or 18,000 m, making it an ideal testing solution for ‘space qualified’ receivers. Simply build a trajectory using user-defined commands or upload an NMEA, KML or VBO File and SatGen will generate a GNSS scenario of that route.

SatGen can simulate any speed and any altitude up to geostationary orbit, with higher altitudes available on request. This provides simulations for a range of space scenarios including rocket launches, CubeSat deployments, satellites, and space probes.

During simulations, the ‘true horizon’ elevation mask mode within SatGen continuously calculates where the horizon would appear when observed from each trajectory point and increases the number of visible satellites accordingly.

This is especially useful for space simulations when the horizon is very low and the number of visible satellites is higher than on the ground. For example, the horizon visible from the International Space Station is at around -20°.

LabSat GNSS simulators are compact yet powerful, offering ideal capabilities for product development testing. The product range – starting at single channel (L1), replay only and ranging up to multi-frequency, record and replay – ensures you can select the model best suited to your requirements without paying for capabilities you don’t need. If you require real-time testing, LabSat Real-Time generates GNSS RF signals with a current time stamp anywhere in the world.

LabSat is also a highly effective production line testing solution. It is easy to use and integrates seamlessly with wider test system set-ups.
