Abstract
A multifunction rangefinder capable of measuring distance, compass location and altitude. A distance measurement unit capable of long and short distance measurements transmits a light beam to a target, receives a reflected light from the target and outputs a distance measurement signal. A compass measurement unit measures terrestrial magnetism and outputs a compass measurement signal. An altitude measurement unit measures atmospheric pressure to generate an altitude measurement signal. A microprocessor calculates a distance between the target and the multifunction rangefinder, altitude and the compass location of the target according to the distance, altitude and compass measurement signals respectively.
