The 3.13X1G code allows the CA to read and display data from a NMEA output GPS sensor, including position, elevation, heading, time etc. Normally this would be achieved with a simple modification to the GPS Analogger device by connecting the GPS's output to the CA's serial input line via the existing TRS cable. The data output stream saved by the analogger then includes a single file with synchronized position information which simplifies uploading and viewing on our trip analyzer web application.
