Abstract:

 


The usability and the accuracy of internet-based position determination services which have gained importance
in recent years is one of the up-to-date subjects of studies. Online processing services have more advantages
than commercial and scientific software; since they are easy to use, require less experience and free because
they get quick results. In this study, GPS observation files in rinex format belonging to 6 stations were
evaluated using Auspos, Magic-GNSS and Opus services then the results were obtained. Three systems
showed the similar results for the results obtained according to 24-hour measurement period. In the second
study, observation files were divided into 12, 6 and 2 hour groups and after the results were obtained they were
compared to 24-hour results. According to the reports, it was seen that the accuracy decreased as the
observation period got shorter. In all three systems, 24 and 12-hour observation accuracy occurs in cm
measures. In 6 and 2 hour periods where the observation period is shorter, accuracy value reaches to 3-4 cm.
According to these results, it is seen that although it generally depends on observation period, internet-based
position determination services sustain adequate accuracy for basic geodetic network application that the
topographical engineering needs.
