Fault tolerant GPS-AOA-SINS integrated navigation algorithm based on federated Kalman filter by Rui JIANG, Jun LI, Youyun XU, Xiaoming WANG, Dapeng LI

“…At present, global positioning system (GPS) was widely used in outdoor positioning.However, the continuous development of cities complicated the positioning environment, resulting in a sharp decline in positioning accuracy.Therefore, the integrated positioning scheme of GPS/5G base station angle of arrival positioning/strap-down inertial navigation system (GPS-AOA-SINS) was adopted, and a fault-tolerant integrated navigation algorithm based on federated Kalman filter was proposed.Based on the GPS-AOA-SINS integrated positioning scheme, the algorithm added fault detection between the federated Kalman sub filter and the main filter, and adaptively adjusted the filter gain matrix of the fault sub filter.Experiments show that the proposed algorithm can effectively detect system faults and deal with them in real time, so as to improve the reliability of the system.…”

Positioning and Navigation Using IMUs and Low-Cost Sensors by Patrick Grates

“…It is possible to supplement consumer navigation systems that are based solely on global navigation satellite system (GNSS) with inertial or magnetic field-based sensors so that an accurate navigation solution can be reached during periods of global positioning system (GPS) denial. A fresh approach uses multiple inertial measurement units (IMUs), three spinning and one unspun, as well as navigation aids for a comprehensive navigation solution. …”
