This page covers the initial information that is useful to know about SatGen 4 before you start using it.

SatGen is a great tool to use when you wish to test your device in locations that you’re unable to visit, including hostile environments and areas with strict travel restrictions. It also eliminates the cost and inefficiency of performing multiple field tests and it allows you to test at any point in time, past or future. You can create scenarios to test specific product attributes, such as geofencing, and you can add timed stops to simulate multi-stop routes.

Running Modes

SatGen 4 has 7 running modes:

  • Demo
  • Single constellation
  • Dual constellation
  • Triple constellation
  • Single Constellation Realtime
  • Dual Constellation Realtime
  • Wideband Realtime

SatGen 4 will automatically open in demo mode unless you have a dongle connected.

Demo Mode

This mode is intended to be used for demonstration and familiarisation purposes.

The demo mode does, however, limit the functionality in the software. It can only use GPS L1 signals, the quantisation is limited to 1 bit, and it can only create scenario files that are up to 120 seconds in duration. This is sufficient for a demonstration scenario, but it is not a duration that can be used as a device testing file.

Operational Modes

To make full use of SatGen 4 and create files for device testing, you have to use a security dongle. You will receive the applicable security dongle when you purchase a SatGen 4 configuration.  

When you install the security dongle for the first time, you must make sure that your computer is connected to the Internet. This will allow for the automatic download of the relevant drivers for your security dongle. 

For normal operation, you must make sure that the dongle is installed and recognised by the computer BEFORE you open the SatGen 4 software. 

When you insert the security dongle into the USB port of your computer, it will automatically install. When it is installed correctly, it will indicate that it is ready for operation with a red light.

SatGen 4 can operate in different running modes depending on the type of security dongle you are using. 

Note: The current running mode will be indicated in the title bar of SatGen 4.
Software Configurations

The SatGen software comes with the following configurations:

  • SatGen 4 Single Constellation – This version allows for easy generation of data into LabSat scenario files for replay with LabSat, LabSat 2 or LabSat 3 simulator systems. The software will create a single constellation file for GPS L1, Galileo E1, GLONASS L1 or BeiDou B1.
     
  • SatGen 4 Dual Constellation – This version allows for easy generation of data into LabSat scenario files for replay with all hardware versions of LabSat simulator systems. The software will create single or dual constellation files for GPS L1, Galileo E1, GLONASS L1 or BeiDou B1 in any two or single-constellation combination.
     
  • SatGen 4 Triple Constellation – This version allows for easy generation of data into LabSat scenario files for replay with all hardware versions of LabSat simulator systems.  The software will create three, two or single constellation files for GPS L1, Galileo E1, GLONASS L1 or BeiDou B1 in any constellation combination.
     
  • SatGen 4 Single Constellation - Real Time – This version allows for easy generation of data into LabSat scenario files for replay with all hardware versions of LabSat simulator systems or Real Time output. The software will create single constellation files for GPS L1, Galileo E1, GLONASS L1 or BeiDou B1 in any two, single constellation combination or a live signal stream to a LabSat RT with less than a 1-second latency.
     
  • SatGen 4 Dual Constellation - Real Time – This version allows for easy generation of data into LabSat scenario files for replay with all hardware versions of LabSat simulator systems or Real Time output. The software will create single or dual constellation files for GPS L1, Galileo E1, GLONASS L1 or BeiDou B1 in any two, single constellation combination or a live signal stream to a LabSat RT with less than a 1-second latency.
  • SatGen 4 Wideband Real Time – This version allows for easy generation of data into LabSat scenario files for replay with all hardware versions of LabSat simulator systems. The software will create triple, dual or single constellation files for GPS L1, Galileo E1, GLONASS L1 or BeiDou B1 in any constellation combination for all LabSat variants or GPS L1C/A, L1P, L1M, L2C, L2P, L2M, L5I, L5Q, Galileo E1, E5a, E5b, E6, GLONASS L1OF, L2OF, BeiDou B1I, B2I, B3I, NavIC SPS L5, SPS S, in LabSat 3 Wideband format only.
Scenarios and Simulations
Scenarios
Simulations
  • Static Scenario 
    Use the inbuilt map to search for a location or enter the coordinates directly.
     
  • Dynamic Scenario
    Use the inbuilt map to draw a dynamic route.
     
  • Script-Based Scenario
    Create a route using either the predefined examples or by entering user-generated commands to control the position, velocity and dynamics of the output file. 
     
  • Leap-Second Scenario
    Create a route that uses custom leap seconds. 
  • Real Time Simulation
    Create a live signal output for the current time or a live signal output for a specified time and date when using a LabSat Realtime or LabSat 4 Realtime unit.
     
  • Space Simulation
    Create an Orbital Trajectory in SatGen 4 or import an NMEA file with the planned trajectory to run a space simulation in SatGen 4. 
     
  • NMEA Streaming
    Stream NMEA Output directly in SatGen 4.
Compatible File Types
  • Google Earth KML file
  • NMEA file
  • VBOX file in VBO format
  • CSV File
