My IBSS base has been up and cooking for the better part of 3 years on a permanent building hard wired into our servers about 5 miles from each end of the project. We still have about 12-18 months to go and as luck would have it the powers that be have decided to not renew the lease on that building and move everything out to the field office site. The field office is a cluster of trailers and connex offices that is in the project limits about 1 mile from one end and 7 miles from the other. Cell coverage over the entire length is no problem. I have never moved a permanent IBSS base. Is it as easy as building the new point and burning it in then moving everything? Are there any pitfalls or booby-traps that I need to look out for? Will my site calibration still be good or need to be re-calibrated? The original control is long gone, there are some secondary but mostly tertiary remains. Any advice? I still have about 5 months to plan this out and get it right.
Thanks,
RH

I had to relocate a base a couple of times on a smaller site after the original control disappeared. As I understand it, any point set using a site calibration can be used as a new base and the calibration still works. Just put the rover on the pole and make sure you get the correct antenna height on it. I would set something at each end and in the middle before it's moved just for a check after it's moved.
As long as you have good solid LLh coordinates on both bases you shouldn't have to redo the calibration. As eddycreek said, just check it, stake to some knowns.
It would be hard to redo it if the points it's based on are gone; I'd probably prefer to live with whatever small amount of error there is between the two bases.
Is there any possibility of running a couple days' worth of 6 or 8 hour static sessions between the two bases? That would be the best thing - you'd have mm level relative positions.
