Figure 11: GPS Antenna Module Harness Connection
The optional Digital BUS-WATCH® GPS antenna module harness plugs into the
back of the DVR as shown in Figure 11 above. This module will track up to twelve
satellites at a time while providing one-second navigation updates at low power
consumption. The GPS antenna module is housed in a black, water-resistant case and
designed to withstand rugged operating conditions. Information provided to the DVR
system includes longitude, latitude, speed, heading, date, and time. Internal memory
backup allows the GPS antenna module to retain critical data such as satellite orbital
parameters, last position, date, and time, to reduce valid data acquisition time.
