LabSat Real-Time

Generate real-time GNSS RF signals for your test regime with a current time stamp anywhere in the world

  • GPS, GLONASS or BeiDou
  • Real-time generation of RF signals
  • SatGen software included
  • Realistic carrier to noise levels
  • Single or dual constellation

Why use a real-time GNSS simulator?

By connecting a real-time simulator to your device it allows you to test GPS RF signals with a current time stamp simulated from anywhere in the world. You can test specific trajectories and geographical locations all from your bench, saving you hours in real world testing.

Using LabSat RT gives you realistic carrier to noise levels and signals all in real-time.

By using SatGen v3 software you can define the position, route, speed, date, and time, as well as the number of satellites included in the data stream. It also gives you the ability to vary the individual carrier to noise levels for each satellite, allowing you to control the data being streamed directly into your device.

By using a powerful PC the system can generate GPS, GLONASS, BeiDou L1 signals in single constellation (1 or 2-bit) or dual constellation signals at 1-bit each.

How does LabSat Real-Time work?

SatGen software generates a live signal stream to a LabSat Real-Time unit. The unit then converts the RF data from digital to analogue with less than 1 second latency.

If you have an NMEA or KML file of your route, you can simply import this directly into the software. Alternatively you can create a scenario from scratch, either by creating a route in Google Maps, or by building a unique trajectory using simple user-defined commands.

Generate your own scenarios

All LabSat Real-Time units are shipped with 500 GB USB hard drives which contain 25 scenarios. These include static scenarios, as well as actual recorded drives, in places such as London, Detroit, and China.

You can also generate your own scenarios using SatGen v3 simulation software. Defining the position, time and trajectory couldn't be easier; simply select a position in Google Earth, and SatGen will convert this into a real-time RF signal.

You can also create a dynamic route by importing an NMEA or KML file. If you have NMEA data in GGA format, you can use this to directly generate the binary file.
