Abstract
Magnetic flux density (MFD) map matching is a technique which can provide absolute position 11 solutions by comparing a series of MFD measurements with a database. Map matching relies on the 12 consistent measurement of the same physical phenomena during the surveying and positioning 13 phases. However, fluctuations in MFD due to alternating current (AC) electricity, influenced by 14 dynamic power requirements, pose a challenge. This paper analyses the characteristics of the influ- 15 ences of AC sources on MFD measurements. It shows that employing spectral filtering can isolate 16 magnetic perturbations from AC sources, which could be used to enhance the magnetic map match- 17 ing’s resilience to this form of temporal change.
