What typically-available surplus receivers do carrier phase measurements[1]? I'm close to putting up a choke ring antenna I scored off of the surplus market on the roof -- I don't think the wife is going to let me build a proper monument in the yard. :-) Hence, I, too, am interested

But to answer the question, the CMC/Novatel series OEM boards, Motorola and Ashtech receivers can all have carrier phase ability. However, the carrier phase capable receivers is not easy to find. The Motorola Oncore VP did have carrier phase output. (with the right option loaded.) In newer
