Welcome to brand new YouCORS user support portal.
many thanks for your support portall.
I wouls like to ask if here is a reference station in London area so i can use it for corrections
YouCORS is not a GNSS base station network like TopNet or Leica SmartNet, it's just online NTRIP caster. So in most cases you should have your own base station. Some users makes their mount points public and you can connect to them, but we can't guaranty a quality of data or up time.
I have found base station at Southend-on-Sea and rebroadcast it to SHOE mount point by YouCORS relay. It's about 50 km from a center of London, but if you are at easter part, it may work for you.
