Abstract：The formula of Givens transformation with weighted parameter which is used to control the estimator range of the navigation satellite ephemeris parameters is deduced. The results show that Givens transformation with weighted parameter not only is steady in numerical computation and efficient in calculation but also can easily give the prior weight of the ephemeris parameters and expediently make the abnormal navigation satellite parameters back into the prescriptive range.
