Notepad++ is a free text editor program that I use for browsing rinex files. It can handle large files much better thane Notepad and doesn't have form...
Canadian PPP service (John)Couldn't this be resolved by just opening the RINEX file in a text editor and adding the antenna H/N/E line? And that way y...
How sure are you that the L2 corrections are reaching the rovers? I am not too familiar with how this is indicated by most manufacturers. But could it...
I believe they read this from the header of the RINEX file.From the RINEX specifications here:ANTENNA: DELTA H/E/N- Antenna height: Height of bottom s...
Sorry, I didn't find it clear from the origional post, but are all rovers running off the same base?If you could narrow it down to: 1) the base statio...
Idea"I was thinking of setting up a control point and taking a static measurement on this point for a several hours, then setting up over the same poi...
Hi Kevin,SBAS is only a correction delivery method where as PPP is a positioning method. Lets look at it from two perspectives: 1) the network side an...
Do you use these receivers often? Or have they been sitting on the shelf for a while.This might be relevant:

Hey Nate,I think Norman summed it up pretty well. "IF this is true, and I have an older GPS set as base. Say, my Legacy E unit, which is L1 L2, and Gl...
Hi Carl,The time for fixing is mainly a function of ionosphere activity and measurement quality (multipath, pseudorange noise etc). To be honest,the m...
That would be considered a hadware failure 😉
Technical ExplanationCarrier phase measurements are very precise and in a GPS receiver we can measure them with mm-cm level measurement accuracy. Howe...
