Abstract

An artificial satellite includes at least one hatch formed in a wall of the artificial satellite coming in contact with dead space of the artificial satellite, and a hatch opening and closing mechanism which opens the hatch, and the antenna is attached to the hatch.

Claims

1. An artificial satellite comprising:

a plurality of first walls which partition a dead space of the artificial satellite, the plurality of first walls comprising a hatch, respectively;

a plurality of second walls which partition the dead space of the artificial satellite, the plurality of second walls being substantially perpendicular to the plurality of first walls, respectively;

a plurality of reflectors which are respectively attached to hatches, the plurality of reflectors being configured to reflect electric waves;

a plurality of radiators which are respectively provided on the plurality of second walls, the plurality of radiators being configured to receive or emit the electric waves; and

a plurality of hatch opening and closing mechanisms which open the hatches, respectively,

wherein a relative position of each of the plurality of reflectors with respect to the plurality of radiators is changed depending on an opening degree or a closing degree of the hatch.

2. The artificial satellite according to claim 1,

wherein each of the plurality of first walls is one from among a ceiling wall and a sidewall of a payload unit in which a mission device unit which executes a mission function of the artificial satellite is contained.

3. The artificial satellite according to claim 1,

wherein the plurality of hatch opening and closing mechanisms open the hatches by a predetermined amount, respectively.

4. The artificial satellite according to claim 1,

wherein the plurality of hatch opening and closing mechanisms adjust the opening degree or the closing degree of the hatches, respectively.
