Abstract
The apparatus for recording vehicle position is designed to provide the user with a system for recording date, time and vehicle position utilizing information available from a Global Positioning System receiver. The recorded information is called a position log. The position log, in the form of a data file, can be transferred to a computer and reviewed at a later time. The apparatus contains devices which detect attempts at altering the position log, making the position log certifiably authentic and usable in legal proceedings. The apparatus has a Global Positioning System receiver, a clock, a microprocessor and independent vehicle motion sensing capability. The apparatus connects to the Global Positioning System antenna and the vehicle battery. All parts of the apparatus are enclosed in a sealed container which prevents alteration of the position log by substituting simulated Global Positioning System data for the real data in the position log.
