Three methods for obtaining a two body fix are presented. For practical use a calculator with magnetic card capacity is necessary. Advantages of the methods are: One simple rule covering all positions is sufficient to avoid ambiguity, the methods can be used in all positions, an approximate position is not necessary, and the fix is calculated directly. One method employs rotation of a spherical triangle and two methods are based on vector calculation.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
