Does anyone know how the age of NTRIP corrections influences horiz/verlical accuracy of a fixed RTK solution? Would be nice to see a test of that.
I read that correction loss for few seconds or even a minute may still be acceptable for some applications. I ask this because I live in Europe where we have a nice dense CORS network equivalent but most countries charge a fee for its usage based on time (units are seconds). So one could save lots of money by asking for corrections less frequently (maybe every 10 seconds or even less).
I want to survey from moving vehicle over many kilometers in length so I can not use my own base station. My plan is to use a virtual CORS station that will move with my vehicle - my county offers such service.
I found one post with vertical test (unknown setup): http://lefebure.com/articles/rtk-correction-data-age-accuracy/
I am interested in similar horizontal test for Reach.
