AN ASTRONOMICAL INFORMATION ACQUISITION SYSTEM USING DIRECTION SENSOR AND GPS

摘要

An astronomical information acquisition system is provided to enable a user to easily observe stars by using a direction sensor and a GPS(Global Positioning System). An astronomical information acquisition system includes a memory unit(50), a direction sensor module(21), a GPS module(24), and a microcontroller(30). The memory unit stores astronomical information corresponding to latitude and elevation information. The direction sensor module includes an earth magnetism sensor and a slope sensor. The GPS module receives a signal from a GPS satellite and detects the position and current time of the direction sensor module. The microcontroller receives orientation and elevation angles from the earth magnetism sensor and the slope sensor and position and time information from the GPS module, calculates the latitude and elevation information of a point in a sphere, and retrieves astronomical information based on the latitude and elevation information.
