Embodiment Construction

[0020] The photoelectric star-finding auxiliary device includes two main parts, the first part is an automatic leveling device 5, and the second part is a laser emitting device 7. In the automatic level keeping device 5, a support 13 is connected to the back of the satellite antenna 4, and an arc concave 8 is arranged on the upper plane of the support 13 rear portion, and the automatic level keeping device 5 is placed on the position of the arc concave 8; The device 7 is located in the bracket 13, the axis of the laser emitting device 7 coincides with the beam axis 1 of the antenna 4, and the automatic leveling device 5 includes a dial bracket 9, a dial 11, a counterweight 12, and the dial bracket 9 is hung on the arc concave 8 The inside is in point contact with the arc concave 8, and can rotate freely. The dial 11 is positioned on the dial bracket 9, and the counterweight 12 is positioned at the lower side of the dial bracket 9.

Abstract

There is a optoelectronic finder assistant set and method, it is a sort of assistant set and method of satellite communications antenna finder pitch angle by using the principle that the optoelectronic indication keep the horizontality automatically with the dial. This method is in that: The first, unfurl the span antennae. The second step, it makes the dial bracket hang in the circle-arc hollowness. The third step, it opens the laser transmitter in order to emit a laser and the laser point to the dial. The fourth step, adjusts the balance weight, it makes the laser which is emitted by the laser transmitter to beat in the dial. The fifth step, according to the demonstrative graduation of the dial which is produced by the laser adjusts the pitch angle, as far as the current demonstrative graduation of the dial is the needed pitch angle. The sixth step, it works in and adjusts the azimuth and the Brewster angle of the antennae, as far as it reaches the best estate accord to the quality of the secondary planet signal.

Description

technical field [0001] The invention provides an auxiliary device and method for satellite communication antenna pitch angle seeking by using the principle of photoelectric indication and dial automatic maintenance of horizontal state. Involved in the field of satellite communications. Background technique [0002] At present, in satellite communication, the positioning of the antenna and the best signal reception quality are achieved by adjusting the elevation angle, azimuth angle, and polarization angle of the antenna. However, in mobile communication, after the antenna is transferred, the horizontal position of the satellite antenna support base varies, which makes the angle inaccurate in the process of adjusting its pitch angle, resulting in the need to repeatedly adjust the pitch angle during the star-seeking process , the time is long and the speed is slow. Contents of the invention [0003] Technical problem: The object of the present invention is to provide an an...
