A BeiDou-like satnav system for the moon? Chinese scientists plot a possible route
China’s lunar ambitions could soon be aided by the construction of 21 satellites for a moon navigation system.
The team from the Beijing Institute of Spacecraft System Engineering proposed the construction of 21 satellites around the moon which would provide real-time, high-precision navigation to support China’s lunar ambitions. “A satellite constellation in near-lunar space can provide real-time, high-precision navigation and positioning for lunar surface movement, landing and take-off, and support high-frequency human exploration of the moon in the long run,” wrote the team led by Peng Jing, deputy chief designer of China’s Chang’e-5 mission. In the second phase, by adding nine satellites and two orbit types, the constellation could provide full-time navigation for the lunar south pole region and support around-the-clock communication between Earth and any place on the moon.
