Abstract
A speedometer unit that uses a standard output of a position determining navigation unit such as a LORAN, GPS, SAT/NAV, OMEGA, or other type navigation unit. The speedometer includes a processor, such as a conventional microprocessor, that has an input for receiving speed information from the navigation unit, which speed information preferably is outputted according to the National Marine Electronics Association (NMEA) 0183 interface standard. The speed information, which according to such standard is outputted in knots per hour, may be converted to miles per hour for display on an analog or digital display disposed in a housing containing the processor. A push button switch or other input device may be provided for controlling an operational mode of the speedometer, for selecting the information displayed on the display and/or for resetting the speedometer.
