How much area does a GPS satellite cover?
Earth's satellites orbit at a wide range of altitudes, so let us take the network of GPS satellites as an example. The GPS satellites orbit at an altitude of about d = 20,000 km. Using the equation above, each GPS satellite can only "see" about 38% of earth's surface in a given instant. Lees verder »
How much area does one satellite cover?

How many GPS satellites are needed to have full coverage of the planet?
Since four satellites must be visible from any point on the planet and the satellites are arranged into six orbital planes, the minimum number of satellites needed to provide full coverage at any location on Earth is 24. Lees verder »
