China has developed and tested a wireless measuring system for rockets, the Science and Technology Daily reported.

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.
