Abstract: The electronic mileage logger has a GPS module, a processor module, a display module, a memory module, and an output module interoperably connected to allow recording, display and printing out of elapsed mileage. The memory module allows dedicated recording of trip mileage. Elapsed mileage is then stored in the memory module. The display module can display present trip mileage or mileage accumulated over a given period. The memory module retains recorded mileage until reset and cleared. The output module may be password protected and can format the mileage log for output to an external device or application, such as a printer, spreadsheet, or the like. Calibration of the mileage logger is provided during an initialization phase of the device.
