LabSat is an exciting and revolutionary new product from GPS experts RACELOGIC

LabSat is ideal for almost any kind of GPS development. It is used to test and develop GPS engines, GPS enabled smartphones, Portable Navigation Devices, GPS tracking systems and much more. It is very well suited to end of line testing as it can represent a real world test as well as a carefully simulated scenario. In addition, LabSat can be used to calibrate GPS products, such as the Racelogic VBOX range.

LabSat by Racelogic is a low cost GPS Simulator (with GLONASS option) which gives you the ability to record and replay real GPS RF data, allowing you to test almost any GPS device with real world signals, from your bench.If you are selling, testing or developing products using single GPS or multi-GNSS engines incorporating GLONASS, then you'll find LabSat makes your job easier and more effective.

LabSat works by digitising the GPS data and then streaming this to a PC via a fast USB link where it is stored and then later replayed back through the device.

As one of the first dedicated GPS Simulators with RF record and playback facilities, LabSat enables real world GPS testing to take place in the laboratory. LabSat is small and rugged, allowing it to be used in the field to continuously record the RF GPS signal in a digital form that can then be replayed at a later date. As LabSat records real world GPS data, this means that all GPS artefacts are faithfully re-produced on the bench. Multipath, ionospheric effects and dropouts can now be recorded and then reproduced with ease. LabSat works with the L1 (1575.42MHz) signal and has no limit on the number of satellites that can be logged. To cover all testing requirements, scenarios can also be generated from scratch using the SatGen software, which can provide simulated data to specific requirements. Playback with Racelogic prepared scenarios is also possible.

Real world GPS phenomena can be seen in test scenarios, such as multipath, drop-outs, tree coverage, and atmospheric effects.

LabSat SatGen Software

LabSat SatGen Software allows you to create a data file which can be replayed on a LabSat which is based on a user-generated trajectory file. This allows you to simulate almost any kind of test, at a set time and date, anywhere in the world.For example, say you are based in the UK, but you have customers for your products in Australia. You can create a test scenario based around Melbourne and check that your equipment works under these conditions.If your GPS equipment is used under very high dynamic conditions, you can create a scenario to check what happens to your product under these conditions. You could simulate an aircraft taking off and going into a vertical climb up to 30,000 feet, and then performing a high-g turn at this altitude, all without leaving your bench!

The screenshot on the right shows the London '.kml' file after it has been imported into the software. All the gaps between the points have been filled in, and the corners rounded off so that no sudden movement unsettles the GPS.

Many aspects of the output can be adjusted; parameters such as maximum accelerations, jerk rates, stationary periods (for initial satellite lock), position smoothing levels and maximum speed, are all user configurable.

A complex driving scenario, around any place in the world would normally be a labour intensive process taking hours to build up using conventional Simulator software, but with SatGen you can generate complex trajectories in literally a couple of minutes!

Another method of defining a trajectory involves typing in simple commands in a text window, as shown on the left. Commands such as 'vel=100@100m' means change the currently velocity to 100km/h over 100 metres. You can specify initial position, time, heading and height, and then during the scenario you can change velocity, heading and height, either over a pre-defined distance or time.
