Description
Technical Field
The invention relates to a method for measuring pitch angle errors of satellite antennas of different models, in particular to a geosynchronous orbit satellite which can also be used for aligning the satellite antennas of broadcast television satellites.
Background
In existing satellite communication systems, the satellite antenna must be aligned with the geosynchronous orbit satellite to ensure that a data link can be established between the satellite ground station and the geosynchronous orbit satellite. The satellite antenna alignment means that the main shaft direction of the antenna to be adjusted and a satellite point to each other, so that the signal-to-noise ratio of the received satellite signal is maximized. In the process of aligning the satellite antenna, an operator generally uses a compass or an intelligent terminal with azimuth perception as an auxiliary tool to calibrate the antenna. Because the compass or the intelligent terminal with the direction perception is generally placed on the connecting rod between the antenna and the signal receiver, and the direction of the connecting rod and the direction of the actual main shaft of the paraboloid of the antenna form an included angle, errors exist between the compass and the measured data of the intelligent terminal.

For a geostationary satellite, under the condition of known orbit position longitude and geographical latitude and longitude information, the pitch angle actually required by aligning the satellite can be calculated, and the calculated pitch angle is recorded. The satellite antenna is aligned with the satellite, namely the main shaft direction of the antenna and the satellite point to each other, so that the signal-to-noise ratio of the received satellite signal is maximized. And placing a compass or an intelligent terminal on a connecting rod of the signal receiver, and recording the pitch angle at the moment. And the included angle degree between the connecting rod direction of the antenna signal receiver and the main axis direction of the antenna paraboloid can be obtained through the angle difference.
The invention is realized by the following steps that 1, under the condition of knowing the longitude of the orbit and the longitude and latitude of the geography, the pitch angle actually needed by aligning the satellite can be calculated, and the calculated pitch angle is recorded as theta1。
And 2, aligning the satellite antenna with the satellite, namely, enabling the main shaft direction of the antenna to point to the satellite, so that the signal-to-noise ratio of the received satellite signal is maximized.
Step 3, placing the compass or the intelligent terminal on a connecting rod of a signal receiver, and recording the pitch angle theta at the moment2。
Step 4, calculating to obtain the included angle between the direction of the antenna connecting rod and the direction of the antenna paraboloid main shaft, wherein the included angle is delta theta = theta2-θ1。
The invention has the advantages that through recording the measurement data of a certain type of satellite antenna, when the operator adjusts the type of satellite antenna again, the pitch angle of the current antenna can be directly calculated through the pitch angle and included angle compensation displayed by the intelligent terminal, and the operator can conveniently and quickly find the direction to align the satellite.
