One embodiment of a position and time-at-position logging apparatus includes a GPS receiver, a microprocessor, memory, a keypad and a data port. The apparatus receives GPS signals and determines therefrom position and time-at-position information of the apparatus, and logs the information in memory in response to a key depression in a manual mode of operation, or in response to a data capture signal in an automatic mode of operation. The data port may be connected to an input device for generating the data capture signal, an output device for data reporting, or to a computer operable to program an operational mode of the apparatus or download a number of sets of information for processing by report generating software resident therein. The apparatus may optionally include a radio transceiver for exchanging data and/or programming information with a remote source, and may further include a vehicle data port for receiving operational data in accordance with various vehicle/engine operating parameters.
