@bill93 You might find this of interest at least with respect to “short” session durations.

@jt50 See my reply to Bill93. I nonetheless make one last try to clarify my objection to the adoption of these receiver performance specifications a...

@jt50 I like the Leica discussion of real-time RTK. I note the proviso that “...among other things the distance...” is important. I did n...

@bill93 As I recollect, the Eckl study used CORS data therefore baselines less than 25 km were unavailable. At the time of the study, CORS required t...

As there is nothing special about my observation file and posting a binary file probably problematic, I attach my three OPUS solutions using the same ...

Obviously you did not read the Journal of Geodesy article I linked. Nor did you do the simple test of running OPUS solutions with close CORS and the s...

@jt50 I am always surprised when people quote these base error + length relative error specifications. First of all, the best of these specification...

First of all, when a benchmark is mentioned as the intended goal of a project my interpretation is that the primary goal is to be determine a height. ...

While some are daunted by the PAGES program, the academic package GAMIT is even more challenging. I recollect a time when a number of folks looked to ...

As indicated previously, PAGES does not use these external file. Bernese does. ?ÿFor information on Bernese see:

Many different length types between two points. These images from:

@totalsurv I agree on the limited benefit in standard baseline processing of waiting for the final precise ephemeris. I still find broadcast performan...

Baseline error over baseline length is proportional to SV error over distance to the SV. Given the current IGS orbit accuracies, the difference betwee...

As previously noted by Norman Oklahoma and Loyal, the US NGS "User Friendly CORS (UFC)" site allows retrieval of .SP3 files (best of the three IGS orb...
