A unique feature of LabSat is the ability to record video at the same time as the GPS RF data. This is achieved using the very powerful Racelogic Video VBOX (price £1995+VAT, two camera system). The Video VBOX is simply placed in the test vehicle at the same time as LabSat, and the internal GPS engine time stamps the video so that the RF data can be synchronised with the video when replayed on the bench. Not only is the video perfectly synchronised, but GPS data is graphically superimposed on the image during recording. This is made possible because LabSat contains an internal GPS engine which is connected to its RF output channel. Therefore, during a replay, this GPS engine tracks satellites contained in the original recording, and the time-stamp from this GPS engine is sent over a separate serial connection to a PC which automatically synchronises with the UTC time embedded in the Video data. You can pause, jump forwards, or backwards on the video, and then when you press play again, the video automatically jumps to the new synchronised position. Because the Video VBOX is also a GPS data-logger with CAN, you can record many other signals at the same time, and overlay these on the video, producing a very powerful test enviornment. All overlaid graphics are user-customisable. For more information on the in-car Video logger, check out the Video VBOX website
