Description

ANTENNA CONTROL APPARATUS FOR SATELLITE SIGNAL RECEPTION SYSTEM}

The present invention relates to an apparatus for adjusting the position of a satellite signal receiving antenna, and more particularly, a friction structure for suppressing vibration caused by its own weight while ensuring that the antenna receiving the satellite signal always obtains an optimal tracking position with respect to the satellite. The present invention relates to a positioning device of a satellite signal receiving antenna that can be suitably adopted for a vehicle (or a mobile vehicle).

As is well known, in the case of communicating a signal including video / audio components or communicating a specific type of data signal through a wireless channel, when an obstacle is located in a transmission path through which the signal is propagated, normal signal communication is performed. You won't lose.

That is, when a broadcast signal or data signal including video / audio components is transmitted from a broadcast station or a satellite signal transmission destination to an unspecified multiple destination or a specific destination via a radio channel (ie, an air wave channel), the broadcast signal or data signal When an obstacle such as a building or a mountain is placed on a transmission path of a so-called 'hard-looking area' (or hearing-affected area), the broadcast signal or data signal is interrupted by the obstacle.

Therefore, in recent years, even when an obstacle is located in the signal transmission path, satellite communication using satellites is being noticed in order not to be affected by the obstacle and to normally communicate with the signal.

Essentially, satellite communication requires a satellite signal reception antenna to receive satellite signals. Since the satellite signal reception antenna must be maintained at a position that always follows satellites, it can receive satellite signals normally. Various methods have been studied and put into practical use to ensure that the antenna always follows the satellite at the optimum direction angle.

As a representative example, a vertical / horizontal positioning device including a plurality of electric motors is separately provided in the vertical direction and the horizontal direction of the satellite signal receiving antenna, so that the gain of the satellite signal received by the satellite signal receiving antenna is improved. The satellite signal reception antenna always follows the satellite by driving the vertical positioning device and / or the horizontal positioning device including the electric motor on the basis.

In addition, in recent years, a mobile device including a taxi or a freight transport vehicle tends to be installed to receive satellite signals, and such a mobile device also needs a satellite signal receiving antenna to receive satellite signals.

However, when the vertical / horizontal positioning device including the electric motor is adopted to follow the satellite by positioning the satellite signal receiving antenna in the vertical direction and the horizontal direction, not only a plurality of electric motors are required. Based on the gain of the satellite signal received at the satellite signal receiving antenna, driving of the vertical / horizontal positioning device including the electric motor is required, which complicates the driving mechanism of the entire satellite signal receiving antenna.

Also, in the method of positioning the satellite signal receiving antenna by the vertical / horizontal positioning device based on the gain of the satellite signal received by the corresponding satellite signal receiving antenna, for example, the satellite signal receiving antenna is used, for example, in a ship. When the ship is agitated in a loaded state, the satellite signal reception antenna is generally in a vertical swing state, and thus the response characteristic is deteriorated due to the variable gain of the satellite signal received by the satellite signal reception antenna. Because of the situation, high-precision positioning of the satellite signal receiving antenna is impossible.

In addition, when a satellite signal receiving antenna is mounted on a moving object including a taxi or a freight transport vehicle, the moving object changes direction from time to time, so that the satellite signal receiving antenna is very difficult to follow the satellite and maintains the moving object.
