Global Positioning System (GPS) is a space-based satellite A PDOP less than six is necessary for accurate GPS positioning.
The accuracy of GPS system is affected by several factors. One such factor is satellite Geometry which represents the geometric locations of the GPS satellites.
As far as satellite- receiver geometry is concern equatorial region tends to produce the best DOP hence more likely to produce better result in GPS positioning

GPS satellites have clock errors within the normal range of 0 to 7 ns satellite geometry over location and time
This might be done to optimise satellite geometry when a new satellite is launched or when an old satellite fails. It is also done to keep the satellites to.
GPS location accuracy also is related to spatial dis- tribution of satellites in the sky. Satellite geometry is good when angles between satellites are wide7.
This location is expressed in latitude and longitude coordinates Fortunately for people who wish to use GPS to fix locations they need not even think about

What is satellite geometry in GPS?
The accuracy of GPS system is affected by several factors. One such factor is satellite Geometry, which represents the geometric locations of the GPS satellites as seen by GPS receiver.How does satellite geometry affect the accuracy of GPS?
When satellites are evenly spread throughout the sky, their geometry is considered strong (lower DOP value). Thus, the more satellites available spread evenly throughout the sky, the better our positional accuracy will be (and the lower the PDOP value).- There are also clocks in the GPS receivers. Radio wave signals from the satellites travel at 186,000 miles per second. To find the distance from a satellite to a receiver, use the following equation: (186,000 mi/sec) x (signal travel time in seconds) = Distance of the satellite to the receiver in miles.
