%X The results of combined GPS/GLONASS single point positioning(SPP) are compared with each other under different observation weights by using single-frequency pseudorange observations and broadcast ephemeris data and then the effect of atmospheric errors on SPP is discussed and analyzed.Finally,the computation of SPP is conducted with the Least Square and Kalman filter algorithms.The results indicate that the combined GPS/GLONASS SPP can achieve accuracies better than 2.5 m in the horizontal components and 4....
