    • PROBLEM TO BE SOLVED: To eliminate a heat loss caused by a spacecraft by supplying an amplified RF signal to a multiplexer means, transmitting the RF signal by a passive transmission subarray antenna connected to the multiplexer, and radiating a heat loss from a reconstructable passive array antenna panel. SOLUTION: Payload panels 12, 14 constructed of a plurality of passive array transmission antennas control an antenna radiation pattern form electronically, use an array-antenna structure body, hold a traveling-wave-tube amplifier(TWTA) and a multiplexer, and execute a heat radiation function and an RF radiation function. In a standardizing panel, an active array receiving antenna 15 is used, and multiple reconstructable antenna patterns to the up-link are generated. In addition, a developed payload radiates all the heat generated inside. Therefore, payload electric power is increased without depending on the dimension of a bus. In this way, power conversion efficiency to the payload can be increased.
    • 要解决的问题:为了通过向多路复用器装置提供放大的RF信号来消除由航天器引起的热损失,通过连接到多路复用器的无源传输子阵列天线发射RF信号,以及从可重建无源阵列辐射热损失 天线面板 解决方案:由多个无源阵列发射天线构成的有效载荷板12,14以电子方式控制天线辐射图形,使用阵列天线结构体,保持行波管放大器(TWTA)和多路复用器,并执行 散热功能和射频辐射功能。 在标准化面板中,使用有源阵列接收天线15,并且产生到上行链路的多个可重建天线方向图。 此外,开发的有效载荷会辐射内部产生的所有热量。 因此,有效载荷电力增加而不依赖于总线的尺寸。 以这种方式,可以增加对有效载荷的功率转换效率。

    • PURPOSE: To constitute the titled device so that each partial mirror face can be developed synchronously at once by arranging seven partial mirror faces in a shape of a tortoise shell, and releasing the holding of a folding part of one place.
      CONSTITUTION: The second partial mirror faces (a), (b) placed so as to be opposed to each other on both sides of the first cross-shaped partial mirror face 11 are attached to the first partial mirror face 11 by a hinge 12, this hinge 12 is provided with a coil spring on the inside, and a force for opening it freely works on it. To said second partial mirror faces (a), (b), the third partial mirror faces a

      2 , b
      1 and b
      2 are attached by a hinge 13, and this hinge 13 also contains a coil spring so that it is opened freely. In case of a folded state, the second partial mirror faces (a), (b), and the third partial mirror faces a
      1 ∼b
      2 are held by a detaining tool 14 and a detaining tool 16, respectively. When developing the mirror faces, the detaining tool 16 is released by releasing the detaining tool 14, and the whole is developed.
