There are a number of different DOP elements which can be used, we will focus on HDOP (Horizontal-DOP). The HDOP can be seen when using gpsmon. The image below has HDOP highlighted; Good accuracy.

Several DOP measurements with different definitions HDOP: Horizontal Dilution of Precision, measures how the geometric distribution of satellites affects the accuracy of the horizontal position, which refers to the longitude and latitude.A

A greater angle between the satellites lowers the DOP, and provides a better measurement (Figure 1). A higher DOP indicates poor satellite geometry (Figure 2), and an inferior measurement cofiguration, or in other words: the lower the

DOP stands for Dilution of Precision. Dilution of Precision is a term used to describe the strength of the current satellite configuration, or geometry, on the accuracy of the data collected by a GPS or GNSS receiver at the time

What is DOP in GPS?
This is often refered to as the geometry. The term DOP means Dilution Of Precision and is a value of probability for the geometrical effect on GPS accuracy The computed position can vary depending on which satellites are used for the measurement. Different satellite geometries can magnify or lessen the position error.
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 is DOP & how does it affect GPS accuracy?
DOP only depends on the position of the satellites: how many satellites you can see, how high they are in the sky, and the bearing towards them. This is often refered to as the geometry. The term DOP means Dilution Of Precision and is a value of probability for the geometrical effect on GPS accuracy
Why is a low DOP value a better positional precision?
A low DOP (Geometric Dilution of Precision) value is indicative of better positional precision because when two satellite rings overlap at right angles, the greatest extent of the overlap is much smaller than if they overlap in near parallel. Thus, a low DOP value represents a wider angular separation between the satellites used to calculate a unit’s position.
What is the difference between PDOP and VDOP?
Thus, PDOP is Position of DOP and can be thought of as 3D positioning or the mean of DOP, and most often referred to in GPS; HDOP is Horizontal of DOP; VDOP is Vertical of DOP. GPS and GNSS receivers communicate with the satellites above to triangulate our position.
What is GDOP & why is it important?
GDOP takes into account the impact of the geometric distribution of all visible satellites on positioning accuracy, making it the most fundamental and comprehensive metric among all DOP types. A good geometric accuracy factor means that satellites are not concentrated in one area and are evenly distributed in different directional areas.
