Question

The GPS constellation provides continuous global service. The type of ______________ used and the number and ______________ of the satellites in view determine ______________.

Answer 1

Answer:

The GPS constellation provides continuous global service. The type of receiver used and the number and the geometric configurations of the satellites in view determine accuracy.

The GPS (Global positioning system) is used to find out the position of an object through the help of satellites ( approximately there are 24 satellites working for this system) orbiting around the earth. These satellites broadcast their messages and it's up to the receiver to combine these broadcasts in order to find it's position. This process is known as triangulation. That is how the receivers play it's role in the accuracy of a position.

       Now coming towards the geometric configurations, when satellites are evenly spread across the sky they gave us more good results, but when they are together at some place then their geometry got weak. In addition to that it's easier for satellites to find out our horizontal positions but difficult to find the objects at vertical positions.

Thats how both of these play an important role in accuracy.

Answer 2

Answer: Receiver, Geometric configuration, accuracy.
