On Estimating the Effects of Clock Instability With Flicker Noise Characteristics

Sier-Chong Ku

Abstract:	Clock instability is an error source to high precision radio metric and radio interferometric observations. Under most circumstances, such observations take place over a period of time within which modern precision clocks reveal a fluctuation characterized by a flicker noise. Ar undesirable property of Clicker noise 18 the correlation among all observations, with hopelessly complicated correlation coefficients. This complication prohibits one from treating flicker noise a random noise in covariance analysis estimating its effects. This paper introduces two alternative approaches. The first is that of generating a sequence of numbers simulating the flicker noise and then treating it as a systematic error.
