"PDOP: Position Dilution in geometric measure of the strength of GPS satellites to the configuration error. The amount of One HundredLocation. PDOP less than 4 offers the highest precision (less than 1 meter). Between 4 and 8, the accuracy is acceptable. More than 8 gives poor accuracy. "

In simple terms, PDOP is an indicator that the GPS coordinates, take that signal strength sufficient enough satellites, satellite positions good, etc. The lower the value of PDOP, the better.
