Extract

The electrical power consumed by an Earth-orbiting satellite is usually generated by panels of solar cells. On a vehicle such as the ESA Orbital Test Satellite the panels are attached, in cantilever fashion, to a relatively rigid centre body upon which are positioned the communication systems, attitude sensors and control equipment. The pay-load limitations of the launch vehicle imply that the relatively large solar panels must be of a lightweight construction and they are very flexible structures as a consequence. Currently-operating satellites do not appear to be troubled by the flexure of their solar panels. However, it is likely that attitude control problems will arise in the next generation of vehicles which will be equipped with considerably larger panels of solar cells.
