  • Page 27 13. The Advanced Playback Control feature on LabSat 2 contains a feature that allows you to repeat the same scenario over again, so that at the end of the scenario replay the LabSat 2 will loop back to the start of the scenario, and start replaying the scenario over again.
  • Page 28 It is recommended to try the 0 dB slider setting (-83 dBm output) first. If the GNSS engine under test does not lock onto the LabSat 2 signal at 0 dB then increase the attenuation slider by 0.5 dB at a time and replay the file. It is also advisable to cold start the GPS / GLONASS device under test after starting each replay to clear any almanac data that the GNSS engine may have stored.
  • Page 29 17. The digital noise function allows degradation of the replayed GNSS signals by mixing a noise source with the original recorded/simulated file. The Digital Noise slider in the LabSat software is used to adjust the output signal from 0% noise to 100% noise. At the 0% noise setting, the signal output is 100% of the original signal. https://en.racelogic.support//Product_Info/LabSat_2/LabSat_2_User_Guide/11_-_LabSat_2_Replaying_GNSS_Data...

  • Page 32 12 - LabSat 2 SatGen v2 Software SatGen v2 software is a powerful tool for defining and creating RF playback scenario files for use with the LabSat Simulator. For many applications LabSat can record and playback real world, live sky data, but there may be times when you need a more controlled, user definable signal.
  • Page 33 Choice of two software programmes: • SatGen v2 GPS Only Simulation Software with ‘LabSat’ 1 bit and ‘LabSat 2’ 2 bit GPS RF data output in static or dynamic modes: User configurable time, date and duration for static scenario creation. SatGen v2 dynamic scenario creation with draw a route, file upload and user defined command options.
  • Page 34 LabSat uses a binary Intermediate Frequency, to down convert GPS RF data into a binary file, whereas LabSat 2 stores GNSS RF data as an IQ binary file. This means that existing LabSat scenarios cannot be run natively on a LabSat 2 or vice versa.
  • Page 35 Scenario, on the LabSat Scenario Converter. The new LabSat 2 scenario created can now be run on a LabSat 2 GNSS simulator. This new scenario contains only GPS L1 RF and or Galileo E1 data. The RF data for other Constellations is not created by the LabSat Scenario Conversion tool as LabSat does not record those constellations data.
  • Page 36 14 - LabSat 2 Interface Modules During recording, the LabSat monitors the digital input pin, precisely recording the event time of LOW to HIGH or HIGH to LOW transitions. The event times are synchronised to the recorded GPS data with a resolution of around 60nS.
  • Page 37 For this reason, we do not recommend that the LabSat is used to replay CAN data onto a vehicle or any other CAN Bus in a safety critical application. Note: It is not possible to use a separate digital input when using one of the interface modules. https://en.racelogic.support//Product_Info/LabSat_2/LabSat_2_User_Guide/14_-_LabSat_2_Interface_Modules...
