I have compiled base file reductions using DPOS and OPUS. I have broken them down into OPUS, JUSTIN and GIODIS.
I am confident the OPUS and GIODIS, use only GPS signals. JUSTIN I believe uses all available constellation data.
Is this the results that we should expect to see, and is one processor preferred over another. I know the OPUS solutions are not processed by DPOS, but its very interesting that the reduced coordinates are similar in one axis or the other, depending on the processor.
I feel that GIODIS with the 8 CORS stations in the reduction, is probably the most diverse solution. The elevation of GIODIS seems to be the lowest, with Justin elevations being the Highest and OPUS elevations being somewhat in the Middle.
So if setting control and using static files, which processor would yield the best real world coordinate, or are there too many variables to account for?
These are all 24 hour files collected at a 30 second epochs.
