Research on the method of medium-long baseline solution only using Fr(φ)
Journal Title: Science Paper Online - Year 2008, Vol 3, Issue 11
Abstract
Because of the lack of cycle slips detection and restoration as well as integer ambiguity determination, dual-frequency observation can not be adopted in the method of baseline solution only using Fr(φ) to correct ionospheric delay. Hence this method can only be used in the solution of short baseline. The method uses GIM given by IGS to correct ionospheric delay and achieves good result in the solution of medium-long baseline. The result indicates that when computing GPS control network consisting of 31 km-107 km side lengths with 24 h observation data, the accuracy of medium-long baseline can reach to 0.2 ppm.
