What Does the Global Positioning System Consist of?
in which the satellites are specifically arranged for maximum coverage over
Earth (Figure 4.1). The way the constellation is designed allows for a person
to be able to receive enough GPS signals to find their location wherever they
are on the planet. Twenty-four satellites is the minimum for a full constellation,
and there are currently several additional operational GPS satellites in orbit to
improve the global coverage.
The job of GPS satellites is to broadcast a set of signals down to Earth from
orbit. These signals (we’ll discuss this later) contain information about the
