specific Embodiment approach

[0019] The specific embodiment of the present invention comprises following two parts:

[0020] (1) The automatic star-seeking method is characterized in that, according to the following steps, the best satellite signal receiving position is found: 1. the receiving satellite and the receiving ground latitude and longitude parameters are preset in the control circuit of the star-finding device, or the horizontal and vertical angle parameters are directly set ; ② Align the direction indicator on the star finder with the south or north or a specific direction, and place it basically horizontally; ③ Obtain the polarization angle of the receiving satellite by looking up the table, adjust the satellite antenna to the polarization angle and fix it ;④Turn on the power, control the satellite antenna to rotate to the position pre-calculated by the control circuit; The strongest signal, if no signal is detected, control the satellite antenna to do a serpentine or spiral search in a large...

Abstract

The related automatic finding-satellite method comprises: 1. pre-setting parameters on receive satellite and receive area longitude and latitude, or the horizontal and vertical angular parameters; 2. aligning the device direction indication mark toward south or other special direction, and putting the device horizontally; 3. adjusting satellite antenna to the polarized angle as table data, fixing the antenna; 4. turning on to rotate antenna to pre-set position; and 5. detecting satellite signal, if there is signal, fine adjusting antenna to the position with strongest signal; or else, searching more area till receiving signal. This invention can precise position satellite with simple structure and cost, and has wide application.

Description

technical field [0001] The invention relates to an automatic star-seeking method and an automatic star-seeking device used in the method. Background technique [0002] Digital satellite TV has developed rapidly in recent years. It uses geostationary satellites to transmit digitally coded and compressed TV signals to the user end. There are two main ways: one is to transmit the digital TV signal to the front end of the cable TV, and then the cable TV station converts it into an analog TV and transmits it to the user's home. This form has been popularized and used in countries all over the world for many years. Another way is to directly transmit the digital TV signal to the user's home, that is: Direct to Home (DTH) way. American Direct TV Company is the first satellite TV operating company to apply this technology. Compared with the first method, the satellite transmission power of the DTH method is large, and it can be received by a smaller antenna, which can be used by ...
