SatGen 4 Release notes

Version 4.1.17 – 22 May 2024

  • Feature: LabSat4 output introduced.
  • Feature: LabSat 3 Wideband and LabSat4 .ini files now contain a list of all signals used in the simulation.
  • Feature: Support for multiple LabSat RealTime units.
  • Feature: Ionospheric and tropospheric delays may be entirely disabled in the Advanced settings.
  • Feature: Implemented a timeline for the simulation which can be navigated via the graphs, and it adds additional functionality such as inserting a waypoint anywhere along the route, and adjusting satellite selection and attenuation at any point in time during the simulation.
  • Feature: Satellite selection and attenuation can now be changed in a scripted scenario using the new "satellite" function.
  • Feature: Added additional graphs that include an overlay to display the number of active satellites during the simulation.
  • Optimization: Geostationary BeiDou satellites are now simulated on all devices, including LabSat2 and LabSat3.
  • Optimization: Artificial noise (software attenuation) quality improved.
  • Optimization: Accuracy of the Klobuchar ionospheric model significantly increased, it now follows the principles from the original paper by John Klobuchar published in 1987.
  • Bugfix: Rare crash related to HASP dongle detection.
  • Bugfix: Inaccurate ionospheric delays when simulating several constellations.
  • Bugfix: Real time simulations are no longer slowed down by redrawing the map.
  • Bugfix: GLONASS PRN 1 had a wrong frequency slot (0 instead of 1)
  • Bugfix: Start Delay and End Delay didn't work for imported NMEA or VBOX trajectories.
  • Bugfix: Datum is now correctly applied to adjust the altitude values during a simulation.
  • Misc: .NET 8 is now required and .NET 8.0.4 is now installed with SatGen
  • Misc: HASP driver updated to version 9.16.
