Problems solved by technology
However, in practical applications, due to the continuous movement of the vehicle, the antenna system mounted on the vehicle will vibrate over the years, resulting in a deviation from the preset initialization reference position
Therefore, after loading satellite data and retrieving satellite coordinates, it is still difficult to control the antenna to precisely point to the desired satellite
[0008] In addition, in the prior art, when users use the antenna system to receive program satellites, they can usually only load satellite coordinates from the database, and then only receive satellite programs carried by a single satellite in each frequency band of a satellite signal
However, in practice, the satellite programs that users prefer are usually sent by multiple different satellites; therefore, when users want to receive satellite programs sent by different satellites, they must re-input the satellite coordinates to make the antenna It is very inconvenient to point to the satellite broadcasting the satellite program and reset the channel to receive the satellite program

The invention discloses satellite locking technology, which is implemented by an antenna system and a satellite locking method on a vehicle and automatically locks one of a plurality of satellites in space according to a channel selection signal. The antenna system and the satellite locking system have the main technical characteristics of: firstly, pre-recording a plurality of satellite coordinates of the plurality of satellites, establishing a plurality of channels and recording the channels and the corresponding satellites in a satellite and channel mapping relationship table; secondly, selecting at least one channel to generate the channel selection signal and capturing satellite coordinate corresponding to the selected channel according to the channel selection signal to send an antenna control signal; and finally, according to an antenna control signal, generating a driving signal to drive at least one antenna to lock and point to the satellite corresponding to the selected channel. The antenna system and the satellite locking method of the invention can automatically adjust the direction of the antenna during channel selection so as to allow the antenna to lock the satellite sending a satellite program.
Description
technical field [0001] The present invention relates to a satellite locking technology, in particular to a satellite locking technology using channel selection signals to lock satellites. Background technique [0002] Thanks to the vigorous development of satellite technology, satellite technology has brought a lot of convenience to human life. Especially in daily life, satellite positioning, satellite phone, satellite broadcasting, satellite navigation, etc. all shorten the distance between people and make human beings feel that the world is close to each other. Among them, satellite broadcasting technology is widely used in satellite program broadcasting, and human beings in every corner of the world can receive important real-time relay programs. [0003] In the known satellite broadcasting technology, it can be roughly divided into fixed-point satellite broadcasting and mobile satellite broadcasting. Among them, the fixed-point satellite broadcasting technology is to se...
