  • the small communication device 20 starts and executes the above-mentioned specific application.
  • the small communication device 20 receives the environmental data from the connected sensor 25.
  • the small communication device 20 determines whether or not the received environmental data satisfies a predetermined condition. Here, if it is determined that the received environmental data does not satisfy the predetermined conditions, the step ends.
  • control data is transmitted to at least one (unspecified number of) space navigation bodies 10 (for example, space navigation bodies 10B and 10C in FIG. 7).
  • At least one space navigation body 10 executes an imaging operation based on the control data received from the small communication device 20 in ST803.
  • the space navigation body 10 transmits the captured image data to the server device 40 via the ground station 30 (via the communication line), and the series of processes is completed.
  • the server device 40 that has received the image pickup data can transmit the received image pickup data to various terminal devices 500 as needed.
  • the terminal device 500 shown in FIG. 7 (in some cases, also the terminal device 500 shown in FIG. 1) does not necessarily have to transmit the imaging request data, and may be applied to any terminal device. ..
  • the space navigation body control system 1 according to the modified example can quickly transmit control data to the space navigation body 10 without going through the server device 40 by executing the operation as described above. Therefore, it is especially useful in the event of a disaster.
  • the technique of the present disclosure is a space navigation body control system, a space navigation body control method, and a server device capable of rapidly transmitting control data to the space navigation body 10 by providing a plurality of small communication devices 20. Can be provided.
