An Azimuth Determination System Using the Navy Navigation Satellites.

摘要

A system has been developed using the Navy Navigation Satellites that can provide azimuth information on a worldwide basis. This capability is particularly useful in the polar regions where conventional navigation systems based on gyrocompasses experience alignment difficulties. In this newly developed system, two antennas separated by 50 to 100 meters are used as an interferometer array to measure phase differences of a satellite signal. Based on this information, it is possible to determine the azimuth of the baseline connecting the two receiving antennas. (Author)
