Problems solved by technology

Accurate tracking of satellites is difficult without regular compensation of the satellite signal sampling period
[0021] As mentioned above, according to the traditional satellite tracking antenna, since the deviation of the satellite tracking signal that may be caused by the motion of the moving object is not compensated when tracking the satellite, it will produce distorted results
Moreover, since the satellite signal sampling period is not correctly compensated according to the rotation period of the sub-reflector when tracking the satellite by sampling the satellite signal, the satellite tracking cannot be performed accurately

Embodiment Construction

[0052] Next, embodiments of the present invention will be described in detail with reference to the above-mentioned drawings.

[0053] Figure 4 is a block diagram showing the structure of the satellite tracking antenna system according to the first embodiment of the present invention.

[0054] According to the satellite tracking antenna system of the first embodiment, the reflector is tilted in at least one specific direction to perform the operation of tracking satellite signals, the satellite signal received at least one position on which the reflector is tilted is sampled, and by comparing the sampled The size of the satellite signal is used to generate an error signal, and the pointing direction of the reflector is compensated so that the reflector is aligned with the main lobe of the satellite signal.

[0055] Figure 4 The satellite tracking antenna system shown includes a reflector 410, an azimuth signal level measurement component 440, an elevation signal level meas...

Abstract

The present invention relates to a satellite tracking antenna system and a satellite tracking method. Step tracking in which the size of a satellite signal sampled in at least one position in which a reflector of the satellite tracking antenna system is tilted is compared to track a satellite is performed, and a measured value of the satellite signal sampled in a specific position in which the reflector is tilted in N-lth tracking and a measured value of the satellite signal sampled in the specific position in which the reflector is tilted in Nth tracking are averaged to compute a value. The reflector is driven according to the value to track the satellite, thereby minimizing a satellite tracking error caused by a sudden movement of a mobile body equipped with the satellite tracking antenna system.

Description

technical field [0001] The present invention relates to a satellite tracking antenna system and a method for tracking a satellite, more particularly, to an antenna system and a method for tracking a satellite, which can reduce the satellite tracking error to a minimum according to the movement of a moving object on which the satellite tracking antenna system is installed. lowest. In the step-tracking operation, the size of the satellite signal sampled at at least one specific position where the reflector of the satellite tracking antenna system is tilted is compared to track the satellite, for the N-1th tracking of the reflector tilt The measured value of the satellite signal sampled at the specific position and the measured value of the satellite signal sampled at the specific position where the reflector is tilted in the Nth tracking are averaged, and the reflector is driven according to the calculated value. [0002] In addition, the present invention also relates to a sat...
