GPS

As Tolkien once said, “Not all those who wander are lost”. This is especially true when we consider the role of waypoints in guiding paths.

In this article, we’ll explore the uses of GPS technology, how it has changed our lives, and what the future of GPS may hold.

This article will give an overview of differential GPS (DGPS) including the basics, its components, and what it can do for you.

Geocaching is a treasure hunt style game using a GPS receiver. Geocaches are meaningful places that someone hand-picked to become a hiding spot.

Have you ever wondered how your GPS receiver works? They use a technique called trilateration, which measures distances, not angles as in triangulation.

Have you ever wondered about your GPS accuracy? A well-designed GPS receiver can achieve a horizontal accuracy of 3 meters or better. But factors affect it.

When selective availability was enabled, this added 50 meters of error horizontally and 100 meters vertically to GPS signals.
