All you guys collecting hours and hours of data to test your ProMark2 units should make use of the time on the units. If you are collecting 6-8 hours (or more), find all the CORS sites in your area that would build a box around you and process and adjust the position ORGI style. It would be a good use for the data, and really good practice working with Ashtech Solutions. But, then you'll need to tie the point to some known HARN (or equivalent) for proofing your ORGI results. You just may be surprised. (Just remember this ain't from the Ashtech/Thales box)
