GNSS receiver rotation tracking loop design for spinning vehicles

In spinning vehicles, phase of the GNSS signal is modulated due to the rotation motion. The phase modulation results in carrier tracking error. In the conventional tracking loop, loop bandwidth has been adjusted in order to reduce the dynamics stress error. However, in the spinning vehicles, this method may not be effective when the vehicles rapidly rotate. This paper proposes a GNSS receiver tracking loop design method for spinning vehicles. In the proposed method, the influence of the rotation motion on the GNSS signal is eliminated by adding rotation tracking loop into the conventional tracking loop of the GNSS receiver. The added loop tracks rotation angle and frequency of the vehicles. The proposed method was verified through computer simulations.
