SPATIAL VIATORIC POSITION FIXING FROM THE VEHICLE: TWO METHODS

Charles T. Dozier

Peer Reviewed

Abstract: THE VIATOR’S position is here thought of as a point on an imaginary sphere which is centered on the sun. The radius of this ethereal sphere is the viator’s distance from the sun’s center. This distance is measurable by the viator by the parallactic angle (p) of the sun’s radius from his position. The ethereal space here considered extends outward from the sun’s center in all directions, but only to such distances as will admit of an instrumentally measurable parallactic angle of say 1.0" of arc when subtended normally by some known and visible solar system distance. For example, using the sun’s radius of, say, 432,050 miles as the known distance, and 1.0" of arc as his measured parallactic angle p, the radius of his current ethereal sphere (Rsv) is:
