Satellite finding system and satellite finding and aligning method

Abstract

The invention provides a satellite finding compass system and a satellite finding and aligning method. The satellite finding compass system comprises a satellite station and an intelligent terminal. The satellite station comprises an electronic compass, an electronic inclinometer, a GPS / Beidou module, a portable satellite antenna, a satellite modem, a control mainboard and a power supply module, wherein the electronic compass and the electronic inclinometer are located on an antenna feed source supporting arm of the satellite antenna, the control mainboard is connected with the intelligent terminal through a network, parameters of all satellites are stored in the intelligent terminal, the intelligent terminal sends the parameters of a selected target satellite to the control mainboard, andthe control mainboard calculates a target azimuth angle, a pitch angle and a polarization angle corresponding to a satellite antenna and feeds back the target azimuth angle, the pitch angle and the polarization angle to the intelligent terminal, and the polarization angle, the pitch angle and the azimuth angle of the satellite antenna are sequentially adjusted till the polarization angle, the pitch angle and the azimuth angle correspond to target parameters. The system is advantaged in that satellite alignment difficulty of a manual portable satellite antenna is solved, manual satellite alignment precision is improved, and the satellite alignment time is greatly shortened.

Description

technical field [0001] The invention belongs to the technical field of communication, and in particular relates to a star-finding system and a method for finding and aligning stars. Background technique [0002] The GEO satellite is in a synchronous orbit of 36,000 kilometers from the earth. Due to the long distance, the wireless signal loss in the Ku / Ka frequency band is serious. The ground communication antenna must be precisely aligned with the antenna on the satellite to communicate. Otherwise, it will not only fail to communicate, but also cause interference from neighboring stars. . Portable satellite stations are widely used in various industries such as public security, fire protection, emergency response, civil air defense, news media, power grids, petrochemicals, border defense, and the military. They are used in various fields such as emergency rescue, stability maintenance, pipeline inspection, and news interviews. An important device to provide a secure high-sp...

Problems solved by technology

In this method, the commercial sensors carried by the smart terminal used have low sensitivity, poor precision, slow response to adjusting the azimuth / pitch attitude, the sensor is easily affected by the surrounding environment, and whether the smart terminal is placed at the designated position of the satellite antenna is in place, clamped, etc. Disadvantages, in areas with harsh environments, especially in areas with complex magnetic fields, it is basically impossible to complete star alignment. Even if you barely align with satellites, you cannot guarantee whether it is the best position for star alignment. It is easy to cause interference from neighboring stars and cause serious consequences.
