gps satellite geometry

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

The space segment of GPS consists of 24 satellites on 6 orbits (approx 22000 km from the centre of the Earth): ? Each satellite carries a

The accuracy with which positions are determined using GPS depends on two factors—satellite geometry and user measurement accuracy Satellite Geometry

GPS makes it possible to precisely identify locations on the earth by measuring distance from the satellites GPS allows you to record or create locations
