Unless you use OPUS Projects for processing, with two receivers you would still get solutions at each with respect to the CORS and not each other. So ...

Take a look at the PDF for Class 5 at my archive site:(or click the house symbol next to my name).Many details. Many pictures. Hopefully, the answers ...

If I understand you correctly, you are asking why the values printed on your antenna differ from those in the NGS antenna information files.The reason...

FWIW,The reason for multi-frequency combinations, in addition to solving for ionospheric effects, is to allow the combination of frequency data in ord...
