Quick Start Guide
The SatGen software helps you to create GNSS test scenarios that mimic the signals transmitted by real GNSS satellites. These scenarios can be replayed with any LabSat, allowing you to evaluate the performance and reliability of GNSS receivers and applications in a wide range of settings and conditions. In a few steps, you can create, define and generate a GNSS simulation that you can replay again and again.
- Download the software.
Download SatGen 4 from the Labsat Website.
- Connect the dongle.
Connect the security dongle to the USB port on your PC:
- Run the SatGen 4 software.
- Import/Create Route.
The new SatGen 4 dynamics engine greatly improves the quality and precision of GNSS/GPS simulations created using the map, with the ability to use road or railway routing in car, train and pedestrian modes. There are 3 methods you can use to create the route in SatGen 4:
Import
If you have an NMEA, KML or VBO file of your route, you can import this directly into the software.
Map Mode
You can define a relatively complicated route in just a few clicks using the built-in mapping tool. Scenarios can include static testing or complex routes with multiple waypoints.
Script Mode
You can create a simulation from scratch, adding your own user-defined commands. A library of pre-defined editable scripting examples is provided.
Example of Route in SatGen 4
- Define Conditions.
- Specify the route Options, such as Dynamics, Altitude, Datum, Target Speed, Elevation mask, etc.
- Edit custom Leap Seconds and Ionospheric delay parameters in the Advanced Options.
- Define manual Almanacs (if required).
- Select specific satellites to simulate in the Satellites tab.
- Generate Scenario.
The software can use the provided route and configuration to generate a fully realistic scenario.
- Open the Create tab and configure the format, save location, file name, and the required signals, quantisation and signal-to-noise ratio for the scenario.
- Click Create File to create the scenario file or Add to Queue if you are creating multiple scenarios.
You can read more about how to create scenario files in the User Guide.
- Run Simulation.
Connect to any Labsat unit to replay a scenario into your Device under Test (DUT).
You can either run the simulation as is, with the time set during the scenario generation, or if you are using SatGen with a Realtime-compatible LabSat unit, you can run the scenario with the current time, using real-time GNSS signals.
You can read more about how to play simulations in the User Guide.
