AEROLOGATION

Abstract:	Each of the instruments noted is universal in the sense that it may be used with any object without computations other than those normally accompanying the use of almanacs. This universality involves a limitation either of the accuracy obtainable from the instrument or of its compactness. With portable instruments the error (exclusive of the observational error) should not be expected to be less than two or three minutes. In some devices, such as homing devices, universality may be unnecessary and greater accuracy desirable, in order not to increase the observational error. For such purposes, we should not overlook the possibilities of specialized computers in which the co-ordinates of a star and two or three derivatives might be set, and the altitude and azimuth for subsequent times derived mechanically with the aid of clockwork, for use by automatic pilots or by other mechanisms.
