LabSat Release notes

v1.02 build 838 - May 2022
-------------------------------------
New Feature: LabSat will emit a ‘Beep’ as a notification of a buffer over or underflow event during record or replay.
             Time into the record/replay that the buffer event occurred will be stated in the corresponding .ini file under the ‘Buffer’ heading.
New Feature: Network security can be enabled within the Labsat ‘LAN’ menu – this will password protect access to the internal SSD via ethernet.
New Feature: Copying files from USB or SD card media to internal SSD now supported.
New Feature: MAC address now displayed within the LabSat ‘About’ menu and on the ‘System Settings’ page of the webserver.
Optimization: added support for Wi-Fi dongles using the MediaTek MT7601 chipset.
Optimization: Adjustment to automatic gain control to optimise quality of recorded signals.
Bug Fix: Telnet command including a play ‘from’ time now overrides the time set in the ‘Play Options’ menu.
Bug fix: LabSat is no longer unable to record a new file if a .ini file from a previous recording is present on the SSD without a matching .LS3W file.

Known issue:
If the RF channel frequency has been configured via the web interface, then accessing the constellation menu will require the settings
to be changed before the user can exit the menu. Therefore, if checking the constellation settings from the front panel, use the ‘Status’ menu
option rather than the constellation menu, to avoid having to change settings. Alternatively, to exit the constellations' menu without
changing/updating the settings, open the web server and select ‘Exit front panel menus’.

v1.01 b838 - February 2014
Supports the new bootloader further optimising the internal battery performance.

v1.01 b831 - November 2013
Fixes signal drop out - drop outs no longer present in replay when 'OK' was pressed during recording.
Adds 'Loop' function to play menu - continuous replay of selected scenario.
Auto-off disabled when connected to external power.

v1.00 b821 - November 2013
Initial release version.

1.0.6 - April 2018
Support added for LabSat 3 Wideband.

1.0.0.30 - July 2015
Initial software release. Software includes GNSS monitor, Video Sync and Serial Proxy functionality.

• Feature: NAVIC (formerly known as IRNSS) L5 signal has been added to SatGen.
• 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. C/N0 can now be reduced by up to 15 dB-Hz in 1 dB-Hz steps. If attenuation is not zero, the same amount of noise is added to all simulated signals.
• Feature: The anti-spoofing flag transmitted in the GPS L1C/A navigation message is now automatically set depending on the selected signals:
  • When L1C/A is simulated, but neither L1P nor L2P: The anti-spoofing flag is ON.
    This tells the receiver that the encrypted Y-Code is transmitted instead of the public P-Code on L1 and L2. 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.
  • When L1C/A is simulated together with any of L1P and L2P signals: The anti-spoofing flag is OFF.
    This tells the receiver that the public P-Code is transmitted on L1 and L2.: HASP drivers version 8.13.
• Optimization: The algorithm responsible for choosing which satellites to simulate in real time mode (when the number of satellites is restricted) has been changed. It now offers better satellite geometry.
• Optimization: RealTime window is now slightly wider to show more satellites by default (it can always be resized if necessary).
• Optimization: Ionospheric delay algorithm improved for situations when the receiver flies through the ionosphere.
• Optimization: Simulation performance improved by 5-10% (depending on the selected signals).
• Optimization: Improved reliability of Real Time simulations– unless a serious problem occurs, individual buffer underruns should not affect the continuity of the signal.
• Bugfix: U-centre KML format from LabSat 3 HDD now supported.
• Bugfix: The simulation without a dongle was interrupted too late, not exactly after 120s.
• Misc: HASP drivers upgraded to version 7.103.

Bug fixes
 - #1714: Record after a replay passes no RF to internal GPS monitor

2.1 - February 2011

 - Full multi-bit support, with the ability to record a single channel in 1 bit or 2 bit mode, or both channels in 1 bit. It will also allow you to replay 2 bit scenarios as 1 bit, whilst displaying the current mode with other critical information.
 - Independent channel attenuation
 - Channel mute: you can now simulate temporary drop outs or replay only one channel from a 2 channel recording by muting the other
 - Disable synthesizers at end of replay: this prevents residual RF transmission at the end of a scenario causing noise on the receiver
 - Add a description to a scenario when recording
 - Display scenario information in a pop-up window, together with details of the LabSat used to record the scenario, the description, and options used
 - Automatic start and replay: passing a scenario name as a command line argument will now cause the software to start up and commence replay immediately.  A-r switch enables repeat.
 - Firmware version reporting - the about screen now shows hardware, firmware and FPGA version information
 - API - the library assembly is now documented and COM registered to allow interaction from numerous other programming environments.  Samples provided in C#, Windows Powershell (scripting), C++, MatLab
 - Supports temporary upgrades to Record + Replay functionality from Replay only or Record only. This means we can now offer a week's upgrade at a low cost by sending you an upgrade file, for you to evaluate the full LabSat record and replay functionality. Contact your dealer for more information!

First release of 2.0 software supporting LabSat 2.
 - Buffer level display in real-time and 10 minute history
