Abstract

The invention provides a mobile satellite television receiving system. The mobile satellite television receiving system comprises an antenna, a servo system and a controller, wherein the servo system is connected with the antenna and adjusts the position of the antenna, the controller adjusts the orientations of the antenna through the servo system according to the direction characteristic of the antenna to align a main lobe of the antenna with a satellite, and when the differential signal of a sampling value of signals received by the antenna is larger than a preset threshold value and the differential signal has a positive value firstly and then a negative value, it is determined that the satellite is captured. By means of the technical scheme, the antenna of the satellite television receiving system can be rapidly and accurately adjusted to a needed direction.

Description

technical field [0001] The invention relates to the technical field of mobile satellite communication, in particular to a mobile satellite TV receiving system suitable for vehicles (ships). Background technique [0002] Zhongxing 9 is a live radio and television satellite launched by my country. Its use effectively solves the embarrassment that users in remote rural areas in China cannot watch radio and television programs. It also provides a broadcast coverage for mobile vehicles such as passenger trains and passenger buses. The most economical and effective means of program transmission. [0003] Different from the traditional fixed receiving method, mobile vehicles such as passenger trains and passenger buses receive satellite signals in motion, and it is necessary to ensure that the vehicle-mounted receiving antenna can always accurately track satellite signals. On the carrier of high-speed movement, the flat-panel antenna is often used as the main body of the communicat...
