LabSat 3 is a single-box device that incorporates a GPS record-and-replay system without the need for a laptop or PC. Racelogic has designed the LabSat3 with convenience at its core: it is small and light, allowing users to record GPS signals in any situation. It will also come with a pre-recorded library of worldwide scenarios to allow engineers to perform immediate bench testing.

LabSat 3 is able to record signals from GPS, GLONASS, Galileo, BeiDou, QZSS, and SBAS, with the top of the range models able to output two channels simultaneously. Both the recording and replay procedures are simple one-touch operations, with data being logged to an SD card.
