SatGen GPS Simulation Software

Posted in Products

SatGen software allows you to create a GNSS RF I&Q or IF data file that can be replayed on a LabSat which is based on a user-generated trajectory file. This allows you to simulate almost any kind of test, at a set time and date, anywhere in the world.

For example, say you are based in the UK, but you have customers for your products in Australia. You can create a test scenario based around Melbourne and check that your equipment works under these conditions.

SatGen complements the LabSat range of GNSS simulators, and is available in single, dual, triple and multi-frequency/multi-constellation versions. The latest version of SatGen can be used to create a single scenario containing all the upper and lower L Band signals for GPS, GLONASS, and BeiDou, and will take advantage of the LabSat 3 Wideband’s ability to read RF data at up to 80 MB/s.

What constellations & signals can I create?

  • Single Constellation - Create single constellation scenario files for GPS L1, GLONASS L1 or BeiDou B1
  • Dual Constellation - Create dual or single constellation scenario files for GPS L1, GLONASS L1 or BeiDou B1
  • Triple Constellation - Create triple, dual or single constellation scenario files for GPS L1, GLONASS L1 or BeiDou B1
  • Wideband - Create LabSat 3 Wideband scenario files for:
    GPS L1 C/A, M, P; L2, C, P, M; L5, I, Q ( L1M, L2M noise created only)
    BeiDou: B1I, B1-2I, B2I (BeiDou B1 special almanac including BeiDou future satellites)
  • Real-Time – Create real-time GPS, GLONNASS, BeiDou L1 signals with the additional LabSat RT dual constellation system

How does SatGen work?

SatGen can be used to create a scenario which replicates very high dynamic conditions, allowing engineers to test their systems work in all environments. You could simulate an aircraft taking off and going into a vertical climb up to 30,000 feet, and then performing a high g-turn at this altitude, all without leaving your bench!

Creating your own scenarios couldn't be easier. If you have an NMEA file which contains GGA data, then you can import this directly into the software or alternatively, you can start from scratch by creating a route in Google Earth, or build a profile using simple user commands.

Developed with the user in mind, this software allows you to create a static scenario, where a position can be manually inserted or easily determined using the integrated Google Maps screen. You can also draw a route by simply clicking-on a series of locations on the map.

SatGen includes a range of predefined command buttons and scenario examples (including figure-of-eight, circle around a point and aircraft take-off). These pre-set scenarios allow you to test a device by making a few simple clicks.

Is SatGen right for you? Why not try it out?

To enable you to experience the full power of the SatGen Simulation Software, we provide a demonstration version which will allow you to try all new features.

It's a full copy of the SatGen software but is restricted to create GPS-only scenarios (no other constellations) for only 120 seconds. This will allow you to trial the use of SatGen in your own test facility or laboratory.

Please note that the SatGen v3 Simulation Software requires a 64 bit windows operation system and will not install on a 32 bit system.

To receive a free copy of this demo version, please complete this form. To purchase SatGen v3, please contact your local LabSat distributor or us directly.
