I am researching articles on GNSS CORS networks that also include corrections from the Galileo constellation, with particular mention to European networks.
First of all, we need to understand that the purpose of CORS service is to provide a stable and self-adaptive coordinate service without users, and its coordinate system must be stable rather than instantaneous.
We know that the coordinate system of GNSS is a transient coordinate system. Although the operation management department of GNSS synchronizes them with ITRF at some time, for example, NGA synchronizes WGS 84 with ITRF2008 (2005.000) and publishes WGS84 (g1762 ') in October 2013, WGS 84 is still changing with time. As a CORS providing Galileo system services, you need to declare the coordinate frame and time of CORS station to users, such as ITRF2014 (2020.000) or itrf2014 (2019.000), etc., and keep the frame and time unchanged in the next few years.
Sir, I am an algorithm engineer of NavInfo, a Chinese science and technology company. I have been participating in the application development of satellite positioning, one of which is to establish a regional CORS service in China. Our service includes Galileo constellation, but we use VRS mode instead of satellite orbit correction and clock error correction.
From the IGS Network ( http://www.igs.org/network), one can check which constellations does each individual station receive. Besides, the interface allows for filtering out the stations based on the target constellation (Galileo in your case) that you would like to use. Besides, you could check the EUREF Permanent Network, which is focused on the European zone: https://www.epncb.oma.be/
