nautical astronomy and oceanic navigation in basic language
navigation and nautical astronomy - free basic program listings (pdf) for programmable calculator Casio fx 5800P
Navigation - formulas : distance, true course (bearing) loxodrome (rhumb line) and orthodrome great circle sailing
You have to insert ( for departure and arrival points ) : latitude and longitude (degrees- minutes-seconds) "-degrees ..... " for south latitude or for west longitude.
example : latitude 10° 25' 18" North - longitude : 30° 52' 54" West
You obtain : true course (rhumb line-loxodrome) and distance in nautical miles
choosing " to finish " = (option) 2 - than "mode 1 comp" - alpha O shows the orthodromic distance
choosing " to continue " = (option) 1 you can go to waypoint 2 and so on - at the last waypoint choosing " to finish " = (option) 2 - than "mode 1 comp" - alpha O shows the orthodromic distance between the last two points and alpha U shows the total sum of the loxodromic distances
Nautical Astronomy - formulas : estimated altitude and azimuth of a celestial body (star, sun, moon or planet) observed with a sextant
You have to insert :
- latitude (degrees- minutes-seconds) "- degrees ........" for south latitude
- star declination : (degrees- minutes-seconds) "-degrees ....." for south decl.
- polar angle : (degrees- minutes-seconds) , "-degrees ...." for west polar angle
example : latitude = 10° 47' 24" North - declination = 22° 12' 18" South
You obtain :
estimated altitude and azimuth.
choosing " to continue "= (option) 1 you can insert declination and polar angle for another celestial body
