Satellite-based surveying

Modern national surveying is based on signals from global navigation satellites.

Graphic depiction of satellite orbits
More than 50 satellites are currently orbiting the planet.

A variety of global navigation satellite systems orbit the Earth.

The signals emitted by these satellites are picked up by receivers on the ground, and together with appropriate software, they can be used for highly precise positioning. In addition to being very accurate and economical, this method has the advantage that a direct line of sight between points is not necessary.
