Sensor Fusion To Improve State Estimate Accuracy Using Multiple Inertial Measurement Units
2021 IEEE International Symposium on Inertial Sensors and Systems (INERTIAL)（2021）
摘要
The growing availability of low-cost commercial inertial measurement units (IMUs) raises questions about how to best improve sensor estimates when using multiple IMUs. This paper reports on the performance of two approaches applied to GPS-denied onboard attitude estimation. The approaches are a virtual IMU approach fusing sensor measurements and a Federated Filter fusing state estimates from sever...
