| Summary: | Today, the widespread use of satellite equipment to determine the location of objects or persons is done in a commercial and common way. Considering that the basis of satellite equipment is non-native and in the possession of foreign countries, in fact as a result, crises such as political tensions or war, due to tracking or sending incorrect information, are unavoidable. Information security is very important, especially in the military field. Also, accurate knowledge of geographic coordinates and positioning of people and equipment are very important. The importance of this issue is evident especially in the case of subsurface navigation where it is not possible to use GPS. In this project, we intend to investigate the possibility of subsurface navigation independent of GPS and using magnetic maps and matching algorithms. Three methods KATO, ICCP and MSD are presented, simulated and compared and RMSE values are calculated. In the results section, we show that ICCP has the best accuracy. The related system design is also discussed.It is very important to use a backup positioning system at times or places where global positioning system is not available. Magnetic navigation methods or positioning using the Earth's magnetic field have recently attracted the attention of researchers and military experts around the world.Key words: Information security, subsurface navigation, independent of GPS, magnetism, matching algorithm, simulation |
