Tundra-Orbit

A Tundra orbit is highly elliptical orbit of a geosynchronous satellite with an inclination of 63.4 ° mostly. The name comes from the interest here to make satellite -based positioning and transmission method can also be used in the farmed tundra zones especially in the northern hemisphere.

Three geostationary satellites capture almost all of the earth's surface, mainly due to the flattening of the " globe " at the poles but only up to a maximum of 81.3 ° latitude. In contrast, covers a constellation of four satellites in tundra orbits the entire earth - including the polar caps - from. A comparable coverage reach satellites in Molniya orbits ( HEO ) with lesser turnaround time of 12 hours and a high eccentricity.
