ABSTRACT:
The automated repeating sextant (ARS) is a navigational instrument suitable for air, sea and land use. The ARS uses an electronic artificial horizon, an A/D conversion board and either microchips or a computer, with software, to read a celestial body's altitude above the horizon repeatedly in a brief period of time, and then compute a line of position from a statistically enhanced mean altitude; after a second or any successive line of position has been obtained the instrument either provides the latitude and longitude of the navigator, or combines the latitude and longitude with a graphic portrayal of the position on a simplified grid map. The instrument averages numerous individual observations and is relatively small, light and fast. The ARS may be embodied in a fully automated, continually-operating mode with a micro-computer, or may be embodied in a handheld version that is switched on and off. The body sighted by the ARS may be either a natural celestial body (sun, moon, navigational planet or navigational star) using light wave signals, or an artificial celestial body (manmade satellite), using radio frequency signals.
