Description
Summary:Free access online GNSS (Global Navigation Satellite System) data processing services are becoming popular since only a single GNSS receiver can do the job. These services are user friendly and easy to use. Thus, no training and a GNSS software package purchase are needed. This means less cost to users. Currently, three online GNSS data processing services provide kinematic data processing option. In this study, GNSS data collected for hydrographic surveying is processed using these online services and positioning precision of these services are compared. The results indicate that with 1s data, decimeter to meter precision can be achieved for both horizontal and vertical coordinates. •GNSS data collected for hydrographic surveying is processed using three online services.•Precision of these online services is compared.•With 1s data, decimeter to meter precision can be achieved for both horizontal and vertical coordinates.•Among the three services, CSRS produced the best results and APPS produced the worst results.
