Free42 Navigation |
| Description: | A set of programs for astronavigation calculations for mirror sextants to run on Thomas Okken’s Free42 Source Code emulator. Bubble sextant corrections like Coriolis and high-altitude terms not considered in this program. Based on programs of the HP 41C Navigation Pac, all code of which is included in the state file. The Pac is required for the observation and fix programs to work. Up to 20 observations of stars, planets, sun or moon can be stored, each with its own full set of parameters including height of eye, DR Lat and Lon. Fixes are calculated using St.Hilaire equal-altitude lines. Intercepts are calculated using the normal form of the line equation, with latitudes expanded by sec (1/cos) of latitude. The full Mercator expansion function is included for possible future use and is resolved using the built-in SOLVER program, so both direct and inverse (latitude-to-meridional parts and vice-versa) can be calculated. |
