The most affordable, portable, and versatile multi-constellation Global Navigation Satellite Simulator on the market.

If you are selling, testing or developing products incorporating satellite navigation chipsets, then you'll find LabSat 3 makes your job easier, quicker and more cost effective.

Why use a GPS simulator?

LabSat 3 records and replays real world data, allowing realistic and repeatable testing to be carried out under controlled conditions. Signal artefacts including multipath, ionospheric effects and signal dropouts are reproduced and there are no limits to the number of satellites used in the test.

Conventional testing usually requires driving the same route multiple times, where conditions vary and satellite constellations change between tests. This can make it very challenging to reproduce and find software errors or reception issues with the device under test. Using LabSat 3 saves many hours of work, allowing you to quickly pinpoint errors and verify 'corner cases' without leaving the test bench.

A very useful feature is the ability to record and replay additional streams of data using the high speed digital port(s) on LabSat3. In this way, CAN bus data, RS232 signals or digital event triggers can be fully synchronised during playback, bringing a whole new level of realism to your bench simulations.

How does it work?

LabSat 3 receives the signal from a standard satellite antenna, but instead of processing each of the received signals to calculate a position fix, LabSat 3 digitises and stores the original satellite signals at a very high bandwidth onto a removable SD card or USB hard drive.

The RF output of the LabSat 3 is then connected to the antenna input of the device under test and the recorded data is replayed back as an RF signal. The device under test will then start to track the satellites as though it was travelling along the same path taken by the LabSat 3 during the original recording.

How easy is it to use?

One touch record/replay makes LabSat 3 extremely simple to operate. With its rugged construction, built in battery and clear display, it is very easy to use the LabSat 3 in the same environment as your product will experience in everyday use, with little or no training.

A free library of pre-recorded and simulated files from around the world is included to get you up and running as quickly as possible.
