SMARTFHON AS MEANS OF THE RAPID GEOGRAPHICAL COORDINATES DETERMINATION WITHOUT GPS-NAVIGATOR

M.M. Zholonko
Annotations languages:

The examples of the simple programs are presented for smartfon (Phython language under Symbian) and their job performances for independent and operative determination of geographical coordinates by an astronomic method without the use of hand calculations and additional tables. The programs were passed testing and demonstrated the high efficiency. Accuracy is determined, mainly, by the sensitiveness of goniometer instrument on condition of agreeing about a computer time with astronomic on time-signals. The basis of work is method of simultaneous determination of observer’s lattitude and longitude by fixed lines of position of two known stars, and also the specially developed noninstrumental method of coordinates determination from sunrise or sunset.
Keywords: astronomic navigation, computer automation of coordinates determination
