Abstract : Instruments for use in solving basic problems of mathematics in navigation are generally complicated and expensive. The present invention teaches a simple instrument for the purpose comprising six L-shaped members, pivoted together with a protractor at each pivot, to indicate the angle between the adjacent legs. The extended axes of the pivot members intersect at a common point, the center of a sphere. The protractors and indicia marks on the L-shaped members indicate the angles sought of the spherical triangle involved.
