LabSat GNSS Simulators
LabSat is a global navigation satellite system (GNSS) simulator, which connects directly to the RF antenna input of a satellite engine and simulates the signals associated with navigation using GPS, Galileo, GLONASS and BDS (BeiDou Navigation Satellite System) satellites.
This allows you to carry out many useful and highly repeatable tests without leaving the office, saving hours of effort.
Many electronic companies benefit from GPS simulators to help develop and test their GNSS products on the bench. You will find that once you have used one, you will never go back!
Record GNSS data
The data for the simulation is either gathered in the field using the RF recording function, or using the SatGen Software. To record real world data, LabSat simply connects to your PC via USB, and the raw signals from a GPS / Galileo / GLONASS / BDS antenna are streamed directly to hard disk. There are no limitations on the number of satellites being tracked or the length of the recording. LabSat can also record from a GNSS simulator and replay this in the lab, which is useful for testing signals that do not yet exist, such as the full Gallileo constellation.
The signal which is recorded is the normal civilian L1 1575.42 MHz type GPS transmission. This is the same signal used in GPS enabled cell phones, Satellite Navigation Devices, asset tracking units and many more. LabSat 2 is also able to record the GLONASS-L1 transmission at the same time with 2-bit sampling, and can also record either GPS or GLONASS alone with 4-bit sampling.

Replay real world data
When the data is replayed, your GPS / Galileo / GLONASS / BDS engine will faithfully re-create the movement and satellite reception encountered during the test, including all original multipath, satellite obstructions and atmospheric effects.
Durable and versatile
LabSat is rugged and can be used in harsh environments. It is very portable (LabSat measures 170mm x 128mm x 38mm whilst LabSat 2 is 170mm x 123mm x 46mm) and is supplied with a mains power supply and an automotive 12v adapter.
There is also the option of a high capacity battery pack. The RF output power level is adjustable over a 32dB range in 0.5dB steps. In addition to the RF output, there is an event marker function which is accurate to 62nS and a 1 PPS (1 pulse per second) output.
Due to the nature of the signals, LabSat data files are usually very large, requiring 1GB of data for 8m 45s of recording. Therefore LabSat units are supplied with a rugged, portable 500GB USB drive. This contains a number of pre-recorded scenarios, and can be used for streaming your own recordings.
Recording External Data
Additional modules allow the logging and replay of external signals such as serial RS232/422/485 signals, CAN and analogue signals.
LabSat has the unique ability to synchronise with the video from a Racelogic Video VBOX, enabling you to record live video and then replay it, synchronised with the GPS data, and shown as a graphical overlay on the video. Find out more.

We supply a remote control OLE application, which means you can fully control LabSat from your own application written in another language. We have sample drivers written in C#, Delphi and LabVIEW.
LabSat units are supplied in a custom padded flight case with a mains power supply, 12v cigar lighter adapter, USB cable, serial cable, various RF connectors to adapt to the target GPS engine, a 500GByte USB disk (36 hours recording using LabSat) with pre-loaded scenarios, LabSat control software and a printed manual.
