Abstract
The position, velocity, time (PVT) and attitude (ATT) measurement system including a Master GPS antenna and a plurality of Slave GPS antennas is disclosed. The system comprises a hardware PVT channel and a hardware ATT channel. After the Master GPS antenna is selected, the hardware PVT channel stays locked on the Master antenna during the measurement time thus optimizing the accuracy of the PVT data. The PVT channel performs the tracking of the visible GPS satellites and generates the tracking data and the PVT data. The ATT channel performs the attitude measurement using all Slave antennas and the PVT tracking data.
