Chinese researchers test autonomous navigation method for deep-space missions

Chinese researchers have tested a deep-space navigation method that could support the country’s planned mission to Jupiter in 2030, according to the South China Morning Post. The technique, known as stellar aberration navigation, uses minute shifts in the apparent positions of stars. By analysing those changes, a spacecraft can estimate how quickly it is travelling and in which direction.

The approach is intended to allow autonomous, real-time navigation without constant dependence on tracking and commands from Earth. The report says the method puts into practice a concept funded by NASA. The supplied material does not identify the researchers or institution involved, nor does it provide the test date, spacecraft used or performance results.

It also does not state whether the technology has been approved for use on the Jupiter mission. The report links the test to China’s stated 2030 Jupiter plans, but the available information does not provide further details about the mission’s spacecraft, launch schedule or scientific objectives.
