Ka band antenna satellite searching system and method

Abstract

The invention provides a Ka band antenna satellite searching system and method. The system comprises a satellite antenna, a frequency converter, a modem, an antenna controller, an antenna servo systemand a GPS antenna, wherein the satellite antenna and the frequency converter are connected; the frequency converter and the modem are connected; the modem and the antenna controller are connected; and the antenna controller is connected with the antenna servo system and the GPS antenna respectively. In the case of satellite searching, the modem transmits the signal-to-noise ratio of satellite signals to the antenna controller, the antenna controller controls the satellite antenna to rotate to the azimuth and the pitching position with the maximum signal-to-noise ratio according to the signal-to-noise ratio. The system and the method have the advantages that the motor system is manipulated to automatically adjust the position of the antenna according to the signal-to-noise ratio, and quick, high-precision, simple and automatic satellite searching is realized.

Description

Technical field [0001] The invention relates to a star system and method, in particular to a Ka-band antenna finder system and method. Background technique [0002] Ka-band is also called 30 / 20GHz band, because of its wide frequency band, it is usually used for satellite communication. Ka-band communication satellites are widely used in daily TV and telephone communications. Ka-band antennas are used to receive signals from Ka-band communication satellites. Star-finding is an important step in using Ka-band antennas. Only when the antenna is correctly aligned with the position of the satellite can the antenna receive the communication signals from the satellite correctly and stably. [0003] At present, most of the satellite antennas require the user to manually search for stars, which has problems such as slow speed, low accuracy, and inconvenient operation. At the same time, due to the narrow beam of the Ka-band and the high accuracy of the antenna finder, the user can only rely...

AI Technical Summary

Problems solved by technology

[0003] At present, most antennas of satellite antennas require users to find stars manually, which has problems such as slow speed, low precision, and inconvenient operation.

At the same time, due to the narrow beam of the Ka-band, the antenna star-finding accuracy is high, and the user can only rely on repeated practice to accumulate experience in the manual star-finding process to slightly improve the star-finding efficiency.

However, most of the Ka-band automatic star-seeking antennas on the market use imported sensors to assist in star-finding. These sensors have problems such as high prices and limited procurement. It is difficult to form large-scale production and cannot be sold and applied in batches.
