Abstract:

A loosely-coupled GNSS and INS integration algorithm has been developed. It implements an approach where user dynamics model is expressed via accelerometer and gyro measurements - that resulted in higher computational efficiency. Satellite pseudorange and pseudorange rate measurements were used to increase accuracy of user’s position and velocity with GNSS solution failures due to low satellite number. The development and test results for the proposed algorithm are presented in this paper.
