Comparison of web based online GNSS data evaluation services

Abstract

RINEX - Receiver Independent Exchange Format is a data exchange format for raw GNSS data.
The first RINEX version was developed in 1989 by W. Gurtner (Teunissen and Montenbruck
2017). In parallel with the GNSS concept, versions such as RINEX 2.XX, RINEX 3.XX, RINEX 4.XX
have been developed. There are different methods for processing RINEX data. These methods
are classical GNSS data evaluation software and web-based online data evaluation services as
an alternative to this software. In the study, different web-based online evaluation services
will be compared and their usability in measurement applications will be examined. Online
services using PPP (Precise Point Positioning) and relative technique will be used to evaluate
the data. 30 seconds of RINEX data obtained from a point belonging to the CORS-TR network
will be sent to different web-based online GNSS evaluation services and the services will be
evaluated by comparing the coordinate values from these services.
