Polar orbit diagram. This orbit (red circle and arrows) is used for observation and mapping satellites making continuous recordings that over time cover the entire Earth, including the polar regions. The satellite observes the strip of land below it as it orbits, and as the Earth rotates, a different part of the Earth is observed with each orbit. The satellite. An example of a satellite in a polar orbit is the Envisat satellite. A typical altitude for a sun-synchronous polar orbit is around 1000 kilometres, and the orbit is usually angled about 8 degrees from the poles.
