Embodiment Construction
[0026] Taking three star sensors as examples below, the present invention will be further described in conjunction with the accompanying drawings. The whole process is as follows: image 3 shown.
[0027] Step 1. Determine that the life of the satellite is 5 years, the initial orbit parameters are shown in Table 1, and the task attitude is the orientation attitude toward the ground.
[0028] Table 1
[0029]
[0030]
[0031] Step 2. Determine the half cone angle θ of the hood of the star sensor z =20°.
[0032] Step 3. Establish the constraint expressions of sunlight and air light when the star sensor is available.
[0033] When the star sensor is available, the star sensor optical axis vector Vector with sun light position Constraints should be met where θ z is the half cone angle of the hood.
[0034] When the star sensor is available, the star sensor optical axis vector with geocentric vector Constraints should be met where θ e is the half-cone angl...
