Abstract：GNSS is a typical two-body problem,which can be treated as a two-order differential system.After three times derivative,the system affect will be removed and the remain high order parts will be noise-like data,which can be used to estimate system noises. Based on differential time serials of observation,a new method to directly estimate the pseudo-range and carrier phase measuring noises is proposed.By composing single differential observation,double differential observation,measuring noise of the receiver and high order clock noise can be separated.Test data show the method is practicable and easy to use.Because it can work on-line,for lots of real-time GNSS integrated system,this method is extremely convenient for prior variance estimating.
