Output Formats

Updated on May 6, 2026

SatGen 4 has the ability to output the defined scenario in the six following formats:

  • LabSat: When the user selects this output format a .bin file will be generated by the software. This file is compatible with the Racelogic LabSat (LabSat 1) hardware variant for replay. This file type only ever contains 1 bit IF data for GPS.
     
  • LabSat 2: When the user selects this output format a .ls2 file will be generated by the software. This file is compatible with the Racelogic LabSat 2 hardware variant for replay. This file type consists of data in I&Q format.
     
  • LabSat 3: When the user selects this output format a .ls3 file will be generated by the software. This file is compatible with the Racelogic LabSat 3 hardware variant for replay. This file type consists of data in I&Q format. LabSat 3 scenarios are generated as a folder containing a number of .ls3 files, each of 2 GB or less.
     
  • LabSat 3 Wideband: When the user selects this output format a .LS3W & .ini file will be generated by the software. These files are compatible with the Racelogic LabSat 3 Wideband hardware variant for replay. This file type consists of data in I&Q format. For this output format both the.LS3W and .ini files must be copied to the LabSat SSD.
     
  • NMEA File: When this output format is selected a .txt file will be generated. This file contains all the scenario details in a NMEA string, this file if required can also be loaded back into SatGen to be regenerated in an alternate format.
     
  • Real-Time – Current Time: When this output format is selected the defined scenario will be output as a digital stream to the connected LabSat RT device. The LabSat RT will then up-convert the stream to an analogue stream with less than one-second latency and output an RF signal with the current time and date. 
     
  • Real-Time – User time: When this output format is selected the defined scenario will be output as a digital stream to the connected LabSat RT device. The LabSat RT will then up-convert the stream to an analogue stream and output an RF signal with the user’s defined time and date.
