LabSat Real-Time

Veröffentlicht in Produkte

LabSat RT uses real-time GNSS RF signals to play multiple satellite signals from up to two constellations with a current time stamp.

If you are developing, testing or selling products incorporating GPS, GLONASS or BeiDou engines then you'll find LabSat RT makes your job quicker, easier and more effective.

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 it work?

SatGen v3 software generates a live signal stream to a LabSat RT 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.

When playing, the PC streams the live data via USB directly into the LabSat RT. The unit then converts the data into a signal stream to replicate the present real-world satellite signals.

LabSat RT operates at the same time on any two of the three constellations:

  • GPS L1 (1575.42 MHz)
  • GLONASS L1 (1602.00 MHz)
  • BeiDou (1561.098 MHz)

How do I generate scenarios?

All LabSat RT 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.

Choice of two variants

To suit all applications LabSat RT comes in two variants:

LabSat RT Replay only
Dual constellation (GPS/Galileo, GLONASS, BeiDou) replay only

LabSat RT Record and Replay
Dual constellation (GPS/Galileo, GLONASS, BeiDou) Record and Replay

Which PC should I use with LabSat RT?

LabSat RT uses SatGen v3 software to create real-time RF signals. This requires a significant amount of PC processing power. We recommend the following PC processors using the Windows 10 (64-bit) operating system.

Single Constellation: up to 16 satellites

  • 4-core Intel i7 3.8 GHz Turbo frequency

Dual Constellation: up to 28 satellites

  • 8-core Intel i7 Extreme 3.5GHz Turbo frequency
  • 10-core Intel Xeon 2.8GHz Nominal frequency
