Accuracy is the ability of the GPS to be honed into a place on earth. Each improvement in quality comes from two criteria:
1) Signal Speed – speed of receiver, speed of the broadcast signal (from the satellite )
2) Differential signal – communications with a known place or object – (permanent structure, or base station
Repeatability refers to ability of a receiver to come back in two weeks and repeat its ability to locate the same exact spot again. If you were camping or fishing 15-20 meters is acceptable. If you are building a skyscraper, one may want improved repeatability of the technology. Time of the day and having line of site to the sky also affects both accuracy and repeatability. Time lapse of 25 minutes or more usually is the first step in gauging repeatability.
