Forming triangles allows you to infer much more information about the deformation than a baseline does. For example, you could calculate strain in add...
A recent paper in the Journal of Geodesy looked at this problem more closely: "... The experiment with low-cost receivers for the SF-DS [single-freque...

Normally we use the azimuth-independent Gaussian radius of curvature:If you need an azimuth-dependent value, then use Euler's formula:-FGN.
Not sure about celestial navigation, but astro-geodetic methods were fairly common decades ago, e.g.:These methods are just not practical anymore, esp...
The first method is correct. It may be called "pooled RMS". Taking the average of squared RMS values is preferable to the average of RMS values, esp...
It affects the transformation from terrestrial frame (ECEF) to celestial frame (ECI), which involves the Earth orientation parameters (EOP). So in pri...
If using the same base station for RTK and PPK (post-processed kinematic), PPK should be no worse than RTK. After all, in RTK you might have less dat...
I think the important keyword is "redistributable" -- so try this one instead:-FGN
It all depends on baseline length. You can try downloading a few days worth of RINEX files, discarding L2 data, then processing one day, two days, et...
So you tried this one:Maybe you need to restart the PC.I'd also try an earlier version of TT, say 8.1 or 8.0.Hope that helps.-FGN.
Congratulations on the initiative. I've just completed the form. I think this document is relevant: ISO/TR 19122:2004 Geographic information/Geomatics...
The correct interpretation for confidence ellipses is they will contain the true position 95% of the time over repeated occupations. (Successive over...
Perfect, exactly the type of specific instructions that I was looking for. I'll give it a try when I return to the office. Thanks! leegreen, post: 3...
Yes, but where exactly in Topcon Tools would the delta values be inserted? If it were in AutoCAD, I'd know how to shift the points. Thanks for the rem...
