Design of Special Calculator for Ship's Position Using Single Celestial Body Positioning

Abstract:

In order to discard some disadvantages of traditional astronomical navigation positioning, such as manual computation and time-consuming, we design a special calculator for locating ship's position, which not only make astronomical navigation positioning calculation quickly and operate instrument simply, but also convenient to carry. The system based on the theory of sun shift line positioning principle use the 32-bit microcontrollers based on ARM Cortex-M3 kernel as the core controller. In this paper, we give hardware design and software process of the system. Through actual test, the results of the testing value and actual value can tally well. Its calculation process only needs a few seconds, also could greatly improve the real-time and accuracy of positioning.
