when you use GPS and want performace, then I assume, that only PPS
signal characteristics is meaningful. so at first compare technical
specs of various GPS receivers. in example there are the Motorola OnCore
products, one expecially designed for timing applications, with hardware
algorithm to select the bests of avaiable satelites. this has much
better PPS accuaracy than the cheaper one:)

the next criterium is OS and hardware which GPS is connected to.
