What Is a Good Pdop Value

With GPS receivers, when satellites are grouped together in the same general area of the sky, the satellite geometry is considered to be weak (higher DOP value). When satellites are evenly spread throughout the sky, their geometry is considered strong (lower DOP value).

What does high Pdop mean?

With GPS receivers, when satellites are grouped together in the same general area of the sky, the satellite geometry is considered to be weak (higher DOP value). When satellites are evenly spread throughout the sky, their geometry is considered strong (lower DOP value).

What does a low DOP value such as 2 indicate?

Thus a low DOP value represents a better positional precision due to the wider angular separation between the satellites used to calculate a unit’s position. Other factors that can increase the effective DOP are obstructions such as nearby mountains or buildings.
