The performance of precise point positioning technique in the Web based GNSS process service

Today in our profession actively use the location positining technique based on the satellites ,new measurment methods and these measurement evaluation programs are needed to develooped. İn this study it's aimed Precise Point Positining (PPP) ,IGS point using GPS and GPS+GLONASS measurments ,in the first part of this study used tree point from IGS network for the purpuse 24 hour daily RINEX data each point are divided into 0.5,1,2,4 and 8 hour segment,in the second part used four point from IGS network for two period (January and Julay) 24 hour daily a week in two period in practice then entine data set both only GPS and GPS+GLONASS measurments.the selected point from IGS network be careful to be in different latitude,points that used in this study obtained from IGS site and the daily cartesian coordinate are receip it a real values, all points processed by using CSRS-PPP and MAGIC-GNSS web based online GNSS service using only GPS and GPS+GLONASS measurs ,then taking the difference from the real values ,resaltus of the values are statistically examined.
