I don't think so. Basically, the signal you get out from the radio part of a GPS system has poor short term stability but great long term stability. If you want good short term stability you need something like a crystal. Ovens around crystals give you much better performance. Of course, it all depends on how good you need and such, but I think an oven is pretty high on the price/hassle vs performance curve. Any GPS box with a good signal out has a good crystal inside it, probably with an oven. Here is a graph of GPS "position" for a non-good antenna position. http://www.megapathdsl.net/~hmurray/leap-second/garmin-rmc.png To first order, 1 ft position error will be 1 ns time error. -- The suespammers.org mail server is located in California.
