Dilution of Precision. A measure of the receiver-satellite(s) geometry. DOP is a geometric calculation of the uncertainty in a position fix. Also referred to as GOP or GDOP.
Dilution of Precision, a description of the purely geometrical contribution to the uncertainty in a position fix. Standard terms for the GPS application are: GDOP: Geometric ( 3 position coordinates plus clock offset in the solution) PDOP: Position (3 coordinates) HDOP: Horizontal (2 horizontal coordinates) VDOP: Vertical (height only) TDOP: Time (clock offset only) RDOP: Relative (normalized to 60 seconds).
The ilution recision measures the relative degradation of the accuracy of the navigation solution based on the constellation geometry. The reported value can be multiplied by the uncertainty in the range measurements (assumed to be the same for all transmitters) to provide the uncertainty in the navigation solution.
dilution of precision. a numerical indicator of the geometric strength of the satellite constellation in relation to positioning at a certain location and time
Dilution Of Precision. A measure of the GPS receiver/satellite geometry. A low DOP value indicates better relative geometry and higher corresponding accuracy. The DOP indicators are GDOP (geometric DOP), PDOP (position DOP), HDOP (horizontal DOP), VDOP (vertical DOP), and TDOP (time clock offset).
ilution recision The fixes obtained from GPS are subject to varying degrees of accuracy depending upon the relative locations of the satellites overhead. The DOP is a good indicator of fix reliability.
Dilution of Precision, errors caused by bad geometry of the Satellites.
Dilution of Precision. A measure of the geometry of the satellites seen by the receiver. DOP relates the statistical accuracy of the satellite measurements to the statistical accuracy of the computed solution. Position Dilution of Precision (PDOP) is a common measure, composed of Horizontal Dilution of Precision (HDOP) and Vertical Dilution of Precision (VDOP). Geometric Dilution of Precision (GDOP) is composed of Time Dilution of Precision (TDOP) and PDOP. The larger the DOP, the less accurate the measurement.

Dilution Of Precision. Analysis of satellite geometry and the impact on accuracy. The receiver estimates the amount of position calculation error using measurements based on several factors that reduce accuracy. Better relative geometry and higher corresponding accuracy result in a low DOP (values between 1-3). A high DOP (4 and above) indicates an increasing more error in the position indicated. The DOP indicators are GDOP (geometric DOP), PDOP (position DOP), HDOP (horizontal DOP), VDOP (vertical DOP), and TDOP (time clock offset). See Position Dilution of Precision.
