Nate, that's one of the things I demonstrated in my ceu course; position 8 feet off using a rtn with cors 25 miles away. But I do have customers who are very cost concerned and thinking of retirement in 5-10 years. One went with the 16k Carlson system (now regrets it and wishes he'd listened to me), but would never go for the T1M/LS, just too costly for his plans. I'm going to need a really strong case for the extra expense for this group of folks (which we all know is a very large one in our aging profession), and others as well really. They typically have yearly billings of under 6 figures, income/profit 50k maybe, and 10 years to retirement. Multiple constellations certainly are the future though. I believe glonass is going to cdma in order to be more compatible as well, and all the others will be using BOC or MBOC (L1C/E1) or something to be able to work together a bit easier. Latest from U.S. gov. is they won't be fully operational until about 2024 though, so the JAVAD team must be working on ways to utilize without the common signal I think (which is why the expense). At any rate, I hate to discount the usefulness of the T2 just yet.Well, Duane, here are my thoughts.
A LOCAL BASE, (regardless of if it's cors base, or your own local one) is always best.
If you take a t2 into the back woods, and set it up, with a post process static observation, off of cors sites, which are 20 miles away, and 40 miles away, you will get results. (especially in woods)
But
You will GENERALLY get better results, from your own local private base, set in the clear, and processed off of DPOS, and carry an LS into the backwoods.
Both work.
But, stick to shorter base lines. It's just going to yield the best data.
And, when Galileo comes on...
Surveyors win.
Plan for the T-1m.
