Abstract: The vehicular navigation systems largely depend on GPS models. The major limitations of GPS receivers towards the course estimation are recognized as a low update rate (up to 10 Hz) and the impossibility to provide continuous navigation solutions in the periods of no signal reception. In this paper we have developed a model for the course estimation from GNSS and IMU systems and analysis of the IMU accuracy and behaviour during the dead reckoning situation. During experimentation we found that the IMU system accurately calculated the heading angle and found to be more effective.
