An improved vector matching algorithm for underwater gravity aided navigation

Improved Particle Swarm Optimization Geomagnetic Matching Algorithm Based on Simulated Annealing

“…Like the terrain and gravity navigation algorithm based on the reference map, the geomagnetic matching algorithm also uses the geomagnetic map as a reference for auxiliary navigation [5]. Considering the differences in data processing, matching algorithms can be divided into batch processing algorithm and sequential algorithm.…”
