Abstract

In this paper, the first method of adjustment, proposed by Josip Ruđer Bošković, is described in detail, on the example on five meridian degrees. Bošković sets three conditions on the data of the lengths of the meridian degrees to calculate corrections that would fix all degrees in order to get a better estimate of true values. The conditions that have to be satisfied are explained by geometric method which Bošković described in all his studies. For the purpose of this paper, in the process of computing these five meridian degrees, data from Bošković original book have been used. Geometric solution, described by Bošković himself, is not easy to understandat first, as this is noted by other authors who have studied Bošković’s method as well. Hence, geometric description of the Bošković’s method is shown in analytical form as well.
