Abstract
A vehicular position and attitude can be accurately determined from GPS signals by positioning a master and two slave orthogonally disposed receiver antennas rigidly mounted together enabling the rotation of the slave receiver antennas about the master antenna. The slave antennas are rotated and then dither back and forth so that differential phase measurements between the slave antennas and the master antenna is nulled in carrier phase alignment of the GPS signals for determining azimuth angles and elevation angles to the GPS satellites for determining the position and attitude of the vehicle.
