Abstract

The definition and calculation methods for the frequency accuracy,stability and drift rate of GPS on-board clocks are introduced.The performance indices of GPS on-board clocks are analyzed based on the IGS(international GNSS service)precise clock data.The results based on the hadamard variance show that the stability(? =1 d) for the Rb clocks of GPS Block IIR satellites is about 1~3?10-14.
