14 sampling perspectives. (a) 6 sampling perspectives are 1, 2, …, and 6. (b) 8 sampling perspectives are 7, 8, …, and 14. The 3d coordinate was taken as the datum, and origin o was the centre of the satellite. The 3d coordinate was divided into eight octagons. The octagon determined by the positive half axis of the , , and axes was the first octagon. The 11th to 14th octant was below the xoy plane, and the octant was marked counterclockwise.
