Abstract:

Each GPS receiver has the ability provide several different types of measurement as pseudo-range, phase observation … Some of problem positioned in GPS technology (or GNSS) name is often taken as the name of correspondent observation are used to solve the problem. The paper shows the system of formula and the results of GPS baseline based on C/A pseudo-range which measured by Hiper Ga, Gb receiver has been converted to RINEX data file. Calculation results are compared with the baseline processing using GPSurvey 2.35 softwave which is recognized in Vietnam. The result of comparison shows that the diviation of coordinates are a few cm from fixed solution processed by GPSurvey 2.35 softwave. Through this, the authors propose about research on processing baseline using phase observation to contribute technology in Vietnam
