Resumen
Los satélites artificiales usan volantes de inercia para su posicionamiento, sistema que les permite tener una vida más larga que el otro sistema osible:
eyectar gases al espacio a gran velocidad por dos toberas de tal manera que formen un par de fuerzas, sistema, que evidentemente tiene una vida limitada a la duración de la materia a eyectar. Se explica cómo funciona este sistema de inercia.

SATELLITES ORIENTATION
Abstract
Satellite orientation in space is important
for continuous solar cell and
antenna orientation. This orientation
is performed by means of flywheels.
The technique allows satellites having
the largest useful life. Is there
any other technique? Yes. It consists
in the use of radial jets, constituted
by two nozzles producing the moment
of a couple. Such a technique
allows a limited life to the system,
since it lasts when the material to be
ejected is finished. The article explains
the functioning of the flywheel
technique
