摘要：Distributed network technology is a new application of inertial navigation technology. A distributed multi-source navigation system, constituted of a distributed inertial navigation system and a multi-senor configuration, can greatly enhance aircraft survival and reliability. Aiming to design a distributed inertial/star sensor/satellite integrated navigation system, this paper studies the structure of the distributed inertial sensor. According to the main node of the inertial measurement unit (IMU), this paper presents an error online calibration method for the integrated navigation system. It establishes the measurement error model of inertial sensor error, including installation error, scale factor error, and random constant error, and designs a 27-dimensional Kalman filter model, including gyroscope and accelerometer error status information. Furthermore, it designs a model of the distributed error calibration for IMU at sub-node. The simulation results show that the proposed online calibration model can effectively calculate the error parameters of the distributed IMU system, effectively enhancing the performance of the integrated navigation system.
