Chapter 4 Analysis on Velocity Measurement Precision of High Dynamic GPS Receiver Carrier Tracking Loop

摘要

The dissertation introduced factor that high dynamic condition influence the velocity measurement precision of GPS receiver's carrier tracking loop. Based on analyses on the measurement error and tracking threshold, the adaptability and tracking precision of carrier tracking loop in high dynamic condition were simulated, the measurement error and the finally velocity precision were expressed in different high dynamic condition. The paper has important theoretical significance for comprehending the velocity measurement precision in high dynamic condition and designing tracking loop that is adapted to high dynamic condition.
