AT-2 is a dual frequency satellite-based two-antenna system that measures true heading. It contains two 80-channel geodetic quality dual frequency GPS/GLONASS receivers packaged in one small box (159 x 49 x 169 mm) that is connected to two antennas whose base-line is fixed at the time of installation. The AT-2 can also be operated in RTK or DGPS mode from an external base station to provide highly accurate position and velocity.
