Star finder and method for finding star by using same

Abstract

The invention relates to a star finder and a method for finding a star by using the star finder. The star finder comprises a feeder module, a beacon receiver, a GPS (global positioning system) module, a master control module and an output module, wherein the feeder module is used for providing a working voltage for an LNB (low noise block downconverter) at a satellite antenna end and transmitting a satellite beacon signal processed by the LNB; the beacon receiver is connected with the feeder module and used for receiving and processing the satellite beacon signal, and outputting an electric level signal corresponding to the satellite beacon signal; the GPS module is used for determining longitude and latitude of a satellite antenna at the current working position; the master control module is respectively connected with the beacon receiver and the GPS module, stored with satellite parameters and used for calculating a satellite aiming parameter of the satellite antenna according to the parameter of the current satellite to be aimed as well as the longitude and the latitude of the satellite antenna; and the output module is connected with the master control module and used for displaying the satellite aiming parameter and the electric level signal. By means of the star finder, all the communication satellites can be tracked; the star finder and the star finding method are provided for rapidly aiming the antenna to the satellite; and the demand of emergency communication is met.

Description

technical field [0001] The invention relates to a satellite star-finding device, in particular to a star-seeker for assisting a satellite antenna to align a satellite according to a satellite beacon level value and a method for using the same to find a star. Background technique [0002] The traditional satellite dish finder generally uses the satellite TV signal as a star-finding reference, that is, input a set of satellite TV signal frequency, character rate and other parameters, when the satellite antenna is aligned with the working satellite, the star finder locks the satellite TV signal, and output a set of DC levels, when the level is maximum, it means the antenna is aimed at the satellite. [0003] The main disadvantage of this satellite TV star finder device is that this type of star finder can only receive satellite TV signals, and use the signal as a reference to carry out antenna alignment. When the satellite TV signal changes, it must be manually adjusted and ope...

Problems solved by technology

[0003] The main disadvantage of this satellite TV star finder device is that this type of star finder can only receive satellite TV signals, and use the signal as a reference to carry out antenna alignment. When the satellite TV signal changes, it must be manually adjusted and operated. Inconvenient; what's more, this type of star finder will not work properly without a TV signal on some communication satellites, so you can't use it to track all satellites
