  • How is DOP calculated?
  • The complete calculation of DOP can be complex and is computed from the geometric relationships between the receiver position and the positions of the satellites being used for navigation. Figure 1 Example of satellites with poor geometry for high DOP values
  • What is a low DOP and a high DOP?
  • In other words, when the satellites are in the optimal configuration for a reliable GPS position, the DOP is low, when they are not, the DOP is high. Four or more satellites must be above the observer’s mask angle for the simultaneous solution of the clock offset and three dimensions of the receiver’s position.
  • What is the difference between HDOP and VDOP?
  • Horizontal DOP (HDOP): This describes the effect of DOP on the horizontal position value. The more good visible satellites low in the sky, the better the HDOP and the horizontal position (Latitude and Longitude) are. Vertical DOP (VDOP): This refers to the effect of DOP on the vertical position value.
  • What does a high DOP mean?
  • In other words, a high DOP is a like a warning that the actual errors in a GPS position are liable to be larger than you might expect. But remember, it is not the errors themselves that are directly increased by the DOP factor; it is the uncertainty of the GPS position that is increased by the DOP factor.
  • What is DOP and GDOP?
  • DOP is often divided up into components. These componets are used because the accuracy of the GPS system varies. The satellites move, so the geometry varies with time, but it is very predictable. GDOP is computed from the geometric relationships between the receiver position and the positions of the satellites the receiver is using for navigation.
  • What are the different interpretations of DOP values?
  • The various interpretations of DOP values are as follows: Highest possible accuracy to be used for applications demanding the highest possible precision at all times. At this level of accuracy, positional measurements are considered accurate enough to meet all but the most sensitive applications.
