A Method of Improving Performance of Measurement Accuracy for GNSS Receiver Under Dynamic Scenarios

摘要

In order to adapt to the application requirements of GNSS receivers in different scenarios, study the method of the performance of dynamic measurement accuracy for GNSS receiver and improve the performance of accuracy for GNSS receiver, a polynomial curve fitting algorithm is proposed in this paper for the application in dynamic and high-dynamic scenarios. In addition, taking the velocity measurement accuracy as an example, we compared the actual output data of the GNSS simulator and the navigation receiver to analyze the influence of various error sources on the velocity measurement accuracy of the navigation receiver and reduce the accidental error. The experimental results show that the performance of measurement accuracy for GNSS receiver has been improved by more than 25%, which provides a basis for the selection of velocity measurement algorithm models for various types of carriers in different scenarios.
