dawn-dusk orbit


Dawn-dusk orbit of RADARSAT-1
A type of sun-synchronous orbit that allows a satellite to be permanently bathed in sunlight. This allows the satellite to be powered almost entirely by its solar panels. RADARSAT-1, for example, travels in a dawn-dusk orbit with an altitude of 798 km, period of 100.7 minutes, and inclination of 98.6°.
