Evaluation of ICCP algorithm for geomagnetic navigation based on hardware-in-the-loop simulation
【Abstract】 The performance of geomagnetic navigation matching algorithm is influenced by many factors.However,the evaluation of algorithm is completely based on computer simulation at present,whose credibility should be validated further. The iterated closest contour point( ICCP) algorithm was studied. First,the factors were analyzed theoretically,which affect the performance of algorithm. Then,the hardware-in-the-loop simulation system of geomagnetic navigation was established. Geomagnetic field simulation environment and magnetic sensor were introduced in the system and the credibility of simulation was improved. Finally,the performance of algorithm was analyzed from measurement noise,matching length,matching region and inertial navigation system( INS) errors based on the hardware-in-the-loop simulation system. The simulation results show that anti-interference of the algorithm,determination of matching length,selection of matching region and influence of INS errors can be evaluated effectively through the hareware-in-the-loop simulation experiments. The method of hareware-in-the-loop simulation can promote the engineering process of geomagnetic navigation and ICCP algorithm.
