Problems solved by technology

[0007] However, although there are many technologies related to the application of the global satellite positioning system in the above-mentioned prior patents, there is no solution for the needs of watching complete and clear satellite programs on moving cars
This is one of the reasons why satellite TV cannot be popularized

Embodiment Construction

[0016] see first figure 1 Shown, it is the circuit system diagram of the embodiment showing the dynamic adjustment control device of the satellite dish antenna pointing on the movable carrier of the present invention, and it configures a satellite dish antenna 2 on a movable carrier 1 (such as a car) Through the satellite dish antenna 2 aimed at the satellites 3a, 3b, 3c in the preset direction and cooperating with a satellite signal receiver 4, the satellite signal receiver 4 can receive the radio waves emitted by the satellites 3a, 3b, 3c Signal 31.

[0017] After the radio wave signal 31 is received by the satellite signal receiver 4, a satellite signal S1 is sent out. The satellite signal S1 simultaneously includes a video signal (Vedio Signal), an audio signal (Audio Signal) and a coordinate signal. The satellite signal S1 can be fed into a satellite program broadcasting device 5 through the existing signal transmission line, so as to broadcast the satellite video signa...

Abstract

The disclosed device includes a device for tracing satellite coordinate and a mechanism for adjusting dish antenna of satellite. The device for tracing satellite coordinate includes following parts: unit for treating satellite coordinate can receive satellite signals and parses a current satellite signal from satellite signals; a coordinate comparator can compare current satellite signal with a setting value of target coordinate stored in working storage; if there is difference between them, a value of coordinate error is output; a microproceesor calculates a modified control signal based on the value of coordinate error, and therefore drives operation of the mechanism for adjusting dish antenna of satellite based on the modified control signal. Thus, corresponding to longitude, latitude and altitude of the satellite, dish antenna of satellite is adjusted.

Description

【Technical field】 [0001] The invention relates to an adjustment control device for a satellite dish antenna, in particular to a dynamic adjustment control device capable of controlling the pointing of a satellite dish antenna on a mobile carrier. 【Background technique】 [0002] In many application fields at present, the technology of Global Positioning System (Global Positioning System, referred to as GPS) has been widely used. For example: car navigation, terrain measurement, satellite TV, satellite broadcasting, satellite communication, military use... and other application fields, it has also reached a very mature stage. Since the position of a moving object can be measured through the satellite positioning system, and the distance, time, speed, altitude and other information can be calculated from it, the application trend of the satellite positioning system will be more extensive. [0003] In order to cope with the future trend, many companies have carried out the rese...
