Weekly Combined Time Series - These are based on the weekly EUREF time series. is performed using the CATREF software. The reference frame is IGS14
Densification Reference positions + velocities - These are based on the weekly EUREF time series + EPOS + velocities of densified (non-EPOS) network. Estimation is performed using the CATREF software. The reference frame is IGS14

This survey aims at testing GNSS Product Portal. This is part of the initial stage of the Pre-Operational Test (POT) activity carried out in the frame of the ongoing EPOS Pre-Operational Phase (POP). More information about our TCS can be found on our landing site.
In short, our TCS provides, in close collaboration with EUREF, the access to GNSS data from thousands of stations in Europe. In addition, it has many quality control processes in place that ensure the accuracy of the data. Next, various analysis and combination centres analyse these data and produce time series, velocities and strain rate maps. These latter products can be downloaded from the Product Portal that is the topic of this survey.
In the coming weeks, the TCS GNSS Data & Products community is going to test some services / functionalities of its portals in order to obtain feedback on its "usefulness" and "functionality". Based on the response we get, we will modify and improve the portals where necessary.
This survey targets diverse communities with different backgrounds, thus some information can be trivial for some people and too skilled for others. You have the opportunity to provide general comments at the end of the survey.
Many thanks in advance for your kind and significant contribution to the building of the TCS GNSS Data & Products community.
