Introduction

We Measure – Why?

Mapping - determining the location

of existing features

Setting-out - marking the location of

new features

How GPS Works….

The whole system revolves around time!!!

Distance = Rate x Time

• Rate = 186,000 miles per second (Speed of Light)

• Time = time it takes signal to travel from the SV to GPS receiver

Page 56: Introduction to Total Station and GPS - sjce.ac.in · Introduction to Total Station and GPS Dr. P. NANJUNDASWAMY Professor of Civil Engineering J S SScience and Technology University

How GPS Works….

A measurement from one satellite locates a point somewhere on a sphere with the satellite in the center.

Page 57: Introduction to Total Station and GPS - sjce.ac.in · Introduction to Total Station and GPS Dr. P. NANJUNDASWAMY Professor of Civil Engineering J S SScience and Technology University

How GPS Works….

A second measurement from another satellite narrows the location of the point to any point on the circle where the two spheres intersect.

Two measurements puts us somewhere on this circle

Page 58: Introduction to Total Station and GPS - sjce.ac.in · Introduction to Total Station and GPS Dr. P. NANJUNDASWAMY Professor of Civil Engineering J S SScience and Technology University

How GPS Works….

A third measurement from yet another satellite puts the location of the point at one of the two points where the third sphere intersects the circle

Three measurements puts us at one of two points
