A description is given of a proposed versatile navigator's aid (NAV-AID) made possible by recent advances in calculator technology. The NAV-AID is a portable microdigital computer which, when used with The Nautical Almanac, solves Celestial, Loran and Omega position fixing problems. Additionally, the NAV-AID contains a Deduced Reckoning computer as well as the capability to perform a variety of standard piloting techniques. Subroutines enable the navigator to calculate useful course line parameters and to handle sextant altitude and Omega skywave corrections. Other course and fix-related quantities are accessible through an Auxiliary Data Mode. An Inverse Mode allows Celestial, Loran and Omega data to be predicted, and a calculator Mode aids in external computations. Anticipated specifications are given.
