Embodiment Construction

[0027] The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0028] see figure 1 , the control method of a kind of mobile carrier satellite antenna receiving and tracking system of the present invention: DPS antenna 40 starts initialization: the zero point position of location antenna azimuth angle and pitch angle, the geographical latitude and longitude that antenna control unit receives GPS signal, then calculates the antenna to satellite Azimuth and elevation angle; DPS antenna star search: the antenna is lifted to the corresponding position according to the calculated azimuth and elevation angle, and then a large-scale search is started. During the search process, the antenna control unit collects the satellite locking level at all times. When the satellite is locked When the level changes, the antenna locks the satellite; DPS antenna tracking: when the antenna locks the satellite, the anten...

Abstract

The invention relates to a satellite antenna. The invention discloses a method for controlling a moving carrier satellite antenna receiving and tracking system. The method comprises the following steps that: the zero positions of the azimuth angle and pitch angle of a parabolic antenna are positioned firstly, and then an antenna control unit receives geographical longitude and latitude signals of a GPS and calculates the azimuth angle and pitch angle of the parabolic antenna to a satellite; the parabolic antenna is lifted up to the corresponding position according to the calculated azimuth angle and the pitch angle, then begins to carry out large-scale search, in the process of searching, the antenna control unit constantly acquires the block level of the satellite, and when the block level of the satellite changes, the antenna locks the satellite; and when the satellite is locked by the antenna, the parabolic antenna is immediately changed into the state of tracking, and in the state of tracking, the parabolic antenna eliminates error signals according to a electronic beam scanning method so as to make the parabolic antenna constantly aim at the satellite. The method for controlling the moving carrier satellite antenna receiving and tracking system has the advantages of high tracking precision, low cost and long service life.

Description

technical field [0001] The invention relates to a satellite antenna. In particular, it relates to a control method of a mobile carrier satellite antenna receiving and tracking system. Background technique [0002] The mobile carrier satellite tracking system is to realize the communication between the earth station and the satellite. Since the satellite signal is extremely weak and has strong directionality, in order to receive a stable signal on a moving carrier (such as a car, ship, train, etc.), the antenna system must be aligned with the satellite in real time. The antenna control unit is used to detect the deviation between the antenna and the satellite in real time to adjust the attitude of the antenna in time to meet the communication requirements. Tracking technology is already at the heart of the antenna control unit. [0003] The tracking technology used by the satellite antenna controller is mainly the radar target tracking algorithm, including step tracking, c...
