Title:
How to provide the magnetic anomaly detection support in an inertial navigation system and an inertial navigation system
Document Type and Number:
Japanese Patent JP6170983
Kind Code:
B2
Abstract:
One example includes an inertial navigation system (INS). The INS includes a navigation controller configured to generate inertial data associated with motion of a vehicle based on at least one navigation sensor configured on the vehicle and based on magnetic anomaly data. The INS also includes a magnetic anomaly INS-aiding system comprising a plurality of magnetometers distributed in a respective plurality of locations on the vehicle. The magnetic anomaly INS-aiding system can be configured to generate the magnetic anomaly data based on magnetic field measurements of a fixed magnetic anomaly at each of the plurality of magnetometers.
