Simple non-electrical methods and devices for orbit determination on the basis of explicit navigation are examined. Principal measuring devices discussed are the sextant, stadimetric instruments, and almucantars. Computational methods for solving the geometric orbital parameters are focused on adaptations of the velocity hodograph. Discussion includes sample problems and a general analysis of inherent errors.
