There is a 10-15 meter 6-conductor cable between the GPS and the recorder
that needs the timing signal. The recorder gets NMEA and a 1 pps signal
from the GPS. The GPS board (now Trimble, I think, but going to a Garmin
board in the near future models), a board with the patch antenna, and an
interface board are housed in the same small package (weatherproof,
waterproof, etc.)
