You're getting a fixed solution on a 50 mile baseline with a 3 min occupation?> What "used" to happen way back when in the old days of these imposs...

Idk what TBC does, but I really doubt that they can use 30 sec interval data to do fast ambiguity resolution with a 3 minute occupation so that tells ...

I've heard the 4-6 hrs time separation is overstated. A study out of the UK showed that 40 minutes was enough change in the constellation that the ben...

Rapid static/fast static are the same. They use an RTK-type algorithm for fast ambiguity resolution. Although you may not notice it from a user perspe...

So, the logging rate is related to fast static vs. static, not the baseline. 30 sec interval for fast static won't work no matter what the baseline is...

The base needs to have 5 sec interval also, and you need a shorter baseline. I bet 20 miles is too far. If you have a base within a few km and logging...

Static post-processing doesn't use the same algorithm as RTK. Static wants data spread over time, that's why 30 sec interval works. Rapid-static is mo...
