China has developed and tested a wireless measuring system for rockets, the Science and Technology Daily reported on Monday.
Developed by the China Academy of Launch Vehicle Technology (CALT), the wireless system has been installed in Long March-3B carrier rocket, which took the communication satellite "APSTAR-6C" into orbit in early May.
Sensors in the rockets are usually connected by cables, which increases the weight of the rocket and causes difficulties in layout design.
Although wireless technology has been widely used in some electronic devices, rockets have to withstand extreme high and low temperatures, strong forces caused by separation, and a complicated electromagnetic environment.

China upgrades spacecraft reentry and descent technology
Beijing (XNA) May 28, 2018
China has successfully tested its new space program's reentry and descent technology, which makes landing heavier spacecraft possible.
Current spacecraft landing methods such as parachute and airbag landings can not satisfy the deceleration needs of heavier manned spacecraft reentry missions, according to China Aerospace Science and Technology Corporation (CASC).
The CASC successfully conducted three experiments, involving upgraded parachute and airbag landing techniques as well as the infla ... read more
