The navigation algorithms are the quintessence of the executable software on portable calculators or PDA as an aid to the art of navigation, this attempt article describe both algorithms and software for "PC-PDA" implementing different calculation procedures for navigation . The calculation power obtained by the languages: Basic, "C", Java, etc. .., from portable calculators or PDAs , has made it possible to develop programs that allow calculating the position without the need for tables, in fact they have some basic tables with the correction factors for each year and calculate the values ​​"on the fly" at runtime .

The astronomical navigation section includes the resolution of the position triangle, the usefulness of a height line, the recognition of stars and the determinant of the height line, in addition to other topics of interest in nautical: tides, naval kinematics, meteorology and hurricanes, and oceanography. All heading measurements made with a magnetic compass or compass must be corrected for magnetic declination or local variation.
