How does 3d Trilateration work?

Trilateration also works in three-dimensions as well, but involves using spheres instead of circles and requires four distances to form a unique solution instead of three. GPS receivers use three-dimensional trilateration to tell you A) where you are on the earth and B) your current height.

What is the principle of Trilateration?

In geometry, trilateration is defined as the process of determining absolute or relative locations of points by measurement of distances, using the geometry of circles, spheres or triangles. In surveying, trilateration is a specific technique. The term true range multilateration is accurate, general and unambiguous.

What is the key function of GIS?

The central function of a geographic information system is to provide a visual representation of data. It is estimated that 80% of the data we consider has a geospatial element of some form. GIS provides a means for that data to be stored in a database and then represented visually in a mapped format.
