Web-based online location services are developed by a number of organizations; User-friendly, unlimited and
mostly free; has become a significant alternative to high-cost scientific and commercial software to achieve GPS data
processing and analysis. When centimeter (cm) level accuracy is desired, it is easily achieved with these services. In
this paper, an experimental study was performed on the LANG station; Institute of Geology to find an accurate analysis
of the most used web-based online services worldwide (namely CSRS-PPP, GAPS). These services use relative and precise point positioning (PPP) solution approaches. In this pilot study, station coordinates were estimated using an online service and GPS Bernese 5.2 processing software from a 24-hour GPS data set, and then the difference in coordinates between stations was calculated. Bernese online services and software. From the evaluations, it is seen that the results for each solution differ by less than 10 mm for the precise point positioning online service. The results show that the position accuracy obtained from the related online services provides a highly accurate solution that can be used in a variety of geodetic analysis and engineering applications.
