DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an antenna control device and, more particularly, to an angle control device for capturing a moving spacecraft.

[0002]

2. Description of the Related Art Generally, in this type of antenna control apparatus, an antenna angle is set based on predicted value data of a moving spacecraft. Is performed. Conventionally, a spiral search method and a square search method have been adopted as an antenna control method for capturing such a spacecraft. Further, a method of calculating a search angle by minicomputer software and outputting the calculated search angle to an antenna device is also employed.

[0003]

In these conventional antenna control devices, when performing a spiral search or a square search, since only a certain spiral or square pattern is provided, the search operation is stopped during the search. Search is taking too long,
It often happens that spacecraft cannot be captured. Also, if you have a search function with minicomputer software,
There is a problem that the software hangs up due to other obstacles, the antenna cannot be controlled, and software development software becomes expensive. SUMMARY OF THE INVENTION An object of the present invention is to provide an antenna control device that can quickly and reliably perform an antenna search and that can be made into general-purpose firmware.

[0004]

An antenna control device according to the present invention is provided with a parameter setting section for inputting initial setting data such as a search mode, a search width, a search dwell time and the like to set a search parameter. A horizontal search angle generator for outputting horizontal search angle data based on antenna angle forecast value data and parameters; a hexagonal search angle generator for outputting hexagonal search angle data based on antenna angle forecast value data and parameters; An output control unit that outputs search angle data to an external antenna device based on an output from the angle generation unit, and a control unit that controls start / stop of the search according to the reception state of the external reception device.

[0005]

The search angle data is generated based on the parameters set from the mode corresponding to the spacecraft and the antenna angle forecast value data, and the angle of the external antenna device is controlled by the search angle data. The search operation is controlled based on the reception state of the external receiving device, and the search is stopped when the spacecraft is captured.

[0006]

Next, the present invention will be described with reference to the drawings. FIG. 1 is a system diagram of one embodiment of the present invention. In the figure, 1 is a parameter setting unit for setting parameters according to the input operation mode, 3 and 4 are horizontal search angle generating units for inputting parameters and antenna angle forecast value data and calculating search angles, respectively. A hexagonal search angle generator 5 outputs an angle of search from each of the angle generators 3 and 4 to an external antenna device to control an antenna angle, and 2 controls start / stop of search. Department.

As initial parameters, initial parameters 6 such as an operation mode (horizontal search, hexagonal search), a search width, a search dwell time and the like according to the orbit of the spacecraft.
Is input from an external device, and the parameter is set by the parameter setting unit 1. On the other hand, the parameters and the antenna angle forecast value data 7 are input to the horizontal search angle generator 3 and the hexagonal search angle generator 4, respectively. , The output control unit 5 sends the search angle data 10
Is output as The control unit 2 controls the calculation of the search angle and the output of the search angle data to the external antenna device ANT in accordance with the start / stop designation 8 from the outside. Further, the control unit 2 receives the reception state 9 from the external reception device RX, and immediately stops the search angle data output when the antenna normally captures the spacecraft.

[0008]

As described above, according to the present invention, the antenna search function as a means for capturing the spacecraft due to the deviation of the forecast value data is made firmware, and the search mode and the search mode are adapted to the characteristics of the orbit of the spacecraft. By generating the pattern, the spacecraft can be quickly captured, and the development cost can be reduced by using it for general purposes.
