Abstract
DESPITE the fact that the observation of an artificial satellite can be carried out only on a small region of the Earth's surface, we can use these measurements for determining the geocentrical co-ordinates of the satellite, if we know the approximate value of its distance from the Earth's centre. The most suitable observations are those in the neighbourhood of the zenith. If we know the inclination of the orbit, we can then determine also the position of the orbital node.
