Abstract: | To evaluate this low-cost navigation system and associated fusion algorithms, validation tests are performed using an experimental system that is designed to acquire real-time data and to perform data fusion. These tests take place at three test sites that include flat and uneven terrain, with or without obstacles. The evaluation results show that this system can achieve positioning accuracy in the range of 0.1 m to 0.5 m with an update rate of 50 Hz. The PVA model-based fusion algorithm can effectively bridge the signal interruption during a GPS signal outage of 30 s. The error model-based fusion algorithm can provide the signals at 50 Hz using the 1 Hz update rate of the complementary Kalman filter. |
