| Abstract: | The time transmission system based on Compass satellite navigation test platform was studied. It regards the satellite common view method as data comparison. The correction value prediction technology and phase compensation technology were used to improve the accuracy and stability of Rubidium clock.This system can be used in the comparison between the local atomic time scale and UTC(NIM) to carry on the comparison to the source on time.It can make the time value of the Compass satellite navigation detection platform be reliable and keep the difference between the local atomic time scale and UTC(NIM) within 10ns to meet the needs of research, development and application of the Compass navigation products . |
