Heliosynchronism and phasing. Application to the SPOT orbit
The advantages of heliosynchronous, phased orbits for remote sensing satellites such as SPOT are recalled; the evolution of a heliosynchronous phased orbit is outlined; and routine SPOT orbital maneuvers are described. A heliosynchronous orbit permits optimal use of solar panels, and assures that lighting conditions and other diurnally varying parameters are similar at each passage. Phasing enables successive images of a scene to be made at the same viewing angle. Methods to calculate heliosynchronism and phasing are shown.
