Bugfix: BeiDou is now simulated correctly using the almanacs downloaded from the server.
GPS ALMANAC FILE DOWNLOAD DRIVERS
Misc: HASP drivers upgraded to version 7.103. This tells the receiver that the public P-Code is transmitted on L1 and L2. When L1C/A is simulated together with any of L1P and L2P signals: The anti-spoofing flag is OFF. SatGen can't simulate the Y-Code, but we set the anti-spoofing flag to ON, because some receivers refuse to work if that flag is OFF. This tells the receiver that the encrypted Y-Code is transmitted instead of the public P-Code on L1 and L2. When L1C/A is simulated, but neither L1P nor L2P: The anti-spoofing flag is ON. Feature: The anti-spoofing flag transmitted in the GPS L1C/A navigation message is now automatically set depending on the selected signals: If attenuation is not zero, same amount of noise is added to all simulated signals. C/N0 can now be reduced by up to 15 dB-Hz in 1 dB-Hz steps. Feature: The carrier-to-noise-density ratio C/N0 is no longer displayed as an absolute value, but it is now expressed as attenuation from the pure signal level. Feature: NAVIC (formerly known as IRNSS) L5 signal has been added to SatGen.

Optimization: Improved reliability of Real Time simulations– unless a serious problem occurs, individual buffer underruns should not affect the continuity of the signal. Optimization: Simulation performance improved by 5-10% (depending on the selected signals). Optimization: Ionospheric delay algorithm improved for situations when the receiver flies through the ionosphere.

Optimization: RealTime window is now slightly wider to show more satellites by default (it can always be resized if necessary). Optimization: The algorithm responsible for choosing which satellites to simulate in real time mode (when the number of satellites is restricted) has been changed. Bugfix: The simulation without a dongle was interrupted too late, not exactly after 120s. Bugfix: U-centre KML format from LabSat 3 HDD now supported. UI Bugfix: Navic signal selection was not preserved between sessions. Bugfix: wrong order of LabSat 3 channels. NET Core 3.1.8 is now installed with SatGen Optimization: Performance improved by 50-82% (depending on the simulated signals and the CPU model). Feature: Navic S-SPS signal is now officially available. As a result the reported number of simulated frequency bands was too high and noise functionality was disabled too early for LS3W. UI Bugfix: Navic L5 was treated as a different frequency than GPS L5 and Galileo E5a. UI Fearture: Support added for allowing stops along a KML route. NET Core version newer than 3.1.3 was not correctly recognised during installation. Bugfix: wrong date (precisely one week forward) was indicated by receivers during the last 2 hours before the end of the GPS week (Saturday/Sunday night).
