In the not very distant past, many organisations began providing online GNSS data-processing services. Some of these services work on the differential positioning principle and some use precise point positioning. Moreover, these services provide the results for both static and kinematic modes - users only need to specify the mode of processing. In this study, both long-period static and short-period kinematic GNSS data are collected at seven NGS sites and processed using GAMIT, Track and online services. Time series from online processing services show a performance of a few decimetres for static data and sub-metre accuracy for 2min of kinematic data.
