Abstract

The invention is a method and apparatus for determining the errors in the orientation coordinates of an antenna array and the spacings of the antennas in the array using radio waves from one or more sources having known positions and an inertial system, the antenna array comprising at least two antennas. The method comprises the steps of placing the antenna array in one or more specified orientations relative to a reference coordinate system, measuring the phase of each radio wave received by each of the antennas in the antenna array from the one or more radio-wave sources for each orientation of the antenna array, and then determining the errors in the array orientation coordinates using the measured phases. The method also includes determining the errors in the spacings of the antennas in the array and determining the errors in the orientation coordinates of the reference coordinate system, in both cases using the measured phases. The invention also includes apparatus for practicing the method utilizing an inertial system for maintaining the reference coordinate system.
