Problems solved by technology
However, when the Euler angles are used to convert the left and right hands, the conversion formulas are different for different axes of the satellite model, and the method of using the Euler angles to adjust the satellite attitude is more complicated and cumbersome, and the gimbal lock is prone to occur. The problem cannot be easily solved; the quaternion represents a four-dimensional vector. For the three-dimensional vector of the satellite model, it is not intuitive enough to use the quaternion to adjust the satellite attitude, which is not conducive to imagination and observation

The present application discloses a method and a related device for adjusting the attitude of a satellite. The method includes: calculating the head-oriented target vector of the satellite model according to the Euler angle and the direction vector of the X-axis in the J2000 coordinate system; Adjust the head orientation of the satellite model and the head orientation target vector; calculate the sailboard orientation target vector of the satellite model according to the Euler angle and the orientation vector of the Y axis in the J2000 coordinate system; according to the current vector of the sailboard orientation of the satellite model and the sailboard orientation target Vector to adjust the orientation of the sails of the satellite model. Calculate the head-oriented target vector and the sailboard-oriented target vector of the satellite model. Based on the current head-oriented vector and the current sailboard-oriented vector of the satellite model, use the vector method to adjust the head-oriented and sailboard-oriented of the satellite model, which can shield the Disadvantages of adjusting satellite attitude by pull angle and / or quaternion; first adjust the head orientation of the satellite model and then adjust the sailboard orientation to effectively avoid gimbal lock.
Description
technical field [0001] The present application relates to the technical field of satellite data processing, and in particular to a method and a related device for adjusting satellite attitude. Background technique [0002] The satellite attitude refers to the space pointing state of the satellite body in orbit. The origin of the Cartesian coordinate system is located on the satellite body, the Z axis pointing to the ground reflects the yaw direction, the Y axis reflects the pitch direction, and the X axis reflects the roll direction. During the operation of the satellite body in orbit, it can switch between tangential mode, ground mode, sun mode, moon mode and other modes. axis, Y-axis and Z-axis, in order to keep the satellite attitude of the satellite model correct after switching modes, it is necessary to adjust the satellite attitude of the satellite model based on the offset of the X-axis, Y-axis and Z-axis . [0003] Generally, the Euler angles and / or quaternions ar...
