title = "A Bioinspired Polarization Sensor/Sun Tracker/IMU Integrated System for Attitude Determination in GNSS-Challenged Environments",
abstract = "Determining attitudes in Global Navigation Satellite System (GNSS)-challenged environments is a key issue. This paper designs a bionic integrated navigation system for attitude determination by integrating a polarization sensor, a sun tracker and an inertial measurement unit (IMU). To improve the robustness of heading estimation, a multi-mode automatic switching algorithm based on threshold values and polarization angle mismatch error is proposed. A self-calibration algorithm for sensor installation errors has also been developed to improve the heading accuracy. Compared with the existing researches, the system proposed in this paper integrates the sun tracker and the polarization sensor for the first time, which could realize continuous attitude estimation during the daytime. To validate the effectiveness of the proposed automatic switching algorithm, a semi-simulation static test was carried out. The results show that the proposed automatic switching algorithm for the integrated system has the best heading estimation performance compared with other methods in terms of robustness and stability.",
