Both US GPS and China’s Beidou Navigation System rely on the accuracy of their clocks for the accuracy of global positioning.

A hydrogen atomic clock is now most accurate due to its high stability, but a pulse star is 10,000 times more stable due to its enormous mass and high spin velocity. The X ray pulse emitted by a pulse star can provide much more accurate time than the hydrogen atomic clock used by GPS and Beidou now.

China is to launch a pulse star navigation satellite next month to greatly enhance the accuracy of the global positioning of its Beidou Navigation System.

It is extremely difficult to master that brand new technology but Chinese scientists are confident that they will be able to do so through the satellite.

    I believe that this device is already in orbit. Testing has not been completed, however.

    With China’s incredible scientific discoveries and innovations in science & technology, how can the great nation prevent scoundrel hegemonic countries like US and Japan from terrorising and stirring up problems for China out of jealousy and hatred. They are hell bent in circling China with missiles as suggested by Hellish Hillary Cl. This 2016 is certainly the year of the golden dragon and shall continue it’s rise to the Zenith.
