Abstract

The invention relates to a handheld satellite communication terminal and a method for guiding a user to align an antenna with a satellite by using the same. The terminal comprises a main control chip, a satellite communication functional block, external equipment, display equipment, a global positioning system (GPS) positioning module, a magnetic field sensor and an acceleration transducer, wherein the satellite communication functional block and the external equipment are connected with the main control chip through a control interface and a data interface respectively; the display equipmentis connected with the main control chip through a display interface; the GPS positioning module is connected with the main control chip through a universal asynchronous receiver/transmitter (UART) interface; the magnetic field sensor is connected with the main control chip through an I2C interface; and the acceleration transducer is connected with the main control chip through a serial peripheralinterface (SPI). In the method, directions to which the satellite and the antenna point are calculated in real time and displayed on a terminal display interface in the form of icon and the user can be guided to conveniently, rapidly, vividly and correctly point the antenna to the direction of the satellite, so that a good communication effect is obtained when the satellite communication terminalis in field application and the problem of inconvenient operation (a large number of auxiliary equipment, time-consuming calculation and an undefined antenna direction) during alignment of the antenna with the defined satellite position of the satellite by a ground satellite communication terminal is solved.

Description

technical field [0001] The present invention relates to a satellite communication terminal, in particular to a hand-held satellite communication terminal used in the fields of transportation, maritime affairs, military affairs and the like and a method for guiding a user to align an antenna with a satellite by the terminal. Background technique [0002] Satellite communication is a communication method that uses communication satellites operating in earth space orbit to forward wireless signals to realize communication between two or more points on the ground. Since satellites operate in extraterrestrial orbits, wireless signal transmission distances are long, and signal attenuation is severe. Therefore, ground satellite communication terminals are often required to align their antennas with satellites to obtain better communication results. When using a satellite communication terminal in the wild, in order to determine the satellite position, it is usually obtained by usin...
