*Geometric Dilution of Precision (GDOP) is a measure of the effect of the geometry of the satellite-beacon configuration on location accuracy. The actual Argos location accuracy depends on both the GDOP value and the quality of the transmitter (frequency stability). As a general rule, a smaller GDOP value yields a more accurate position.
