- Abstract
Basic algorithms for geomagnetic matching have bad real-time performance in data batch processing, and these basic algorithms have to specify the length of matching sequence data in advance. To solve these two problems, the iterative evaluation matching algorithm (IEMA) is presented for geomagnetic navigation. IEMA learns from the iterative idea, which makes the calculation time distribute in each sampling time and IEMA uses real-time evaluation, which can determine whether to output the matching positioning results after one iterative solution. Results show that IEMA is effective and reliable in geomagnetic navigation, and it can adjust the length of matching sequence data adaptively.
