The GPS (Global Positioning System) receiver and antenna are conveniently on a daughter board located within one of the Mini Loggers (J1939, OBD or ADAQ loggers). This is a major accomplishment since it removes the need for an external cable and external antenna. It also does not require the logger to have a direct view of the sky.
The GPS data is merged with the in-vehicle network or analog data into one data file.
HEM Data provides more power when combining GPS with a DAWN Dashboard. A DAWN Dashboard can provide geofencing, a web-based display of vehicle trips, and the current vehicle location.
GPS parameters include: latitude, longitude, altitude, vehicle speed and heading (direction). The Universal Time clock (UTC), popularly known as GMT (Greenwich Mean Time) provides a time standard, especially if more than one acquisition device is used, or if vehicles are in different time zones.
