The GPS constellation calls for 24 satellites to be distributed equally among six orbital planes. Notice how the number of satellites in view from a given point on the Earth's surface, in this example at 40°N, changes with time. A satellite constellation is a group of artificial satellites working together as a system.

The 5B variant may also be considered for launching satellite constellations in the future using the Yuanzheng upper stage. [ 24 ] The first flight of the 5B variant ("Y1 mission") carried an uncrewed prototype of China's future deep space crewed spacecraft , and, as a secondary payload , the Flexible Inflatable Cargo Re-entry Vehicle .
Besides the 28 lunar mansions, most constellations are based on the works of Shi Shen-fu and Gan De, who were astrologists during the period of the Warring States (481–221 BCE) in China. In his Shiji , the Western Han era historian Sima Qian (145–86 BCE) provided a star catalogue that includes 90 constellations. [ 9 ]
