Abstract
For a driving session that includes maneuver events associated with a vehicle, each maneuver event being defined as a movement of the vehicle from a start position to an end position with an associated start time and end time, a method includes sending an anchor GPS message for each maneuver event. The anchor GPS message includes an anchor fix that includes fix, time, speed and heading with no delta modulation. Subsequent GPS messages are sent with delta modulations of the fix, time, heading and speed relative to the anchor fix.
