At present, the main orientation methods include satellite orientation, gyro orientation, astronomical orientation, etc. However, due to the limitations of observation mechanism and the constraints of external conditions, the above methods still have problems such as harsh environmental requirements, low operating efficiency, low measurement accuracy, insufficient reliability, and even inability to measure in some special environments. Therefore, it is urgent to break through the bottleneck of existing technologies and realize high-precision, high-efficiency and high-reliability orientation in complex and unfavorable observation environments.
[0003] Beidou is often used for high-precision orientation. However, Beidou has strict requirements on the observation environment. In areas with more satellite obstruction or severe multipath effects, the orientation accuracy drops rapidly. The gyroscope can independently determine the true north direction by sensitively sensing the effect of the earth's rotation, but it requires a long time and multiple observations, has low work efficiency, and the instrument constant is easily disturbed by external vibrations and temperature changes, and the orientation accuracy is not high. Astronomical orientation is often required to be carried out on a clear and cloudless night, and it is impossible to achieve rapid orientation around the clock. Summary of the invention
