LabSat

LabSat is a GPS simulator which connects directly to the antenna input of a GPS engine and simulates the signals associated with navigation using GPS satellites. This allows you to carry out many useful (and highly repeatable) tests without leaving the office, saving hours of effort.

The data for the simulation is either gathered in the field using the RF recording function, or by means of the LabSat SatGen Software. To record real world data, LabSat simply connects to your PC via USB, and the raw signals from a GPS antenna are streamed directly to hard disk. There are no limitations on the number of satellites being tracked or the length of the recording.

When the data is replayed, your GPS engine will faithfully re-create the movement and satellite reception encountered during the test, including all original multipath, satellite obstructions and atmospheric effects. The signal which is recorded is the normal civilian L1 1575.42Mhz type GPS transmission. This is the same signal used in GPS enabled cellphones, Satellite Navigation Devices, asset tracking units and many more. LabSat is very portable (170mm x 128mm x 38mm) 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 configurable TTL synchronisation pulse (1Hz to 1KHz).

Additional modules allow the logging and replay of external signals such as serial RS232/422/485 signals, CAN and analogue signals. Due to the nature of the signals, LabSat data files are usually very large, requiring 1Gbyte of data for 8m 45s of recording. Therefore LabSats are supplied with a rugged, portable 250Gbyte USB drive which contains a number of pre-recorded scenarios, and is a place where you can stream your own recordings.

Video Synchronisation

LabSat has the unique ability to synchronise with the video from a Racelogic Video VBOX, enabling you to record livevideo and then replay it, syncronised with the GPS data, and shown as a graphical overlay on the video.

Remote control

We also 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.
