The Earth-orbiting artificial satellites 31a, 31, and 31b, which orbit in various directions with respect to the axis of rotation of the Earth 30, are equipped with a central processing unit, a storage device, a software program with a translation function, and a repeater equipped with a wireless device. ing. The plurality of small-scale utilization stations 2a to 2d are earth-orbiting artificial satellites 31a and 31. b, and can exchange messages with other small-scale stations. In the satellite communication system, multiple users 3 use a communication line branched from the terminal device of the corresponding small-scale user station, for example 2b. We also do translations between.

It is not clear whether the message is being sent or when the sent message will be received by the other party. In other words, confirmation of messages addressed to oneself and translation of the contents of the communication become confusing.

得られる。Next, a communication method in this embodiment will be explained. In FIG. 2, for example, when the small-scale usage station 22t sends a message to the small-scale usage station 2I:1 and an unspecified usage station, the earth-orbiting artificial satellite 12L sends a message to the small-scale usage station 2I:1 and an unspecified usage station. The message is sent while passing through the communication area of station 2a. Then, the storage device 8 in the earth-orbiting artificial satellite 1a stores the contents of the message (term I'J, presence or absence of dormitory language translation, etc.). In this case, when the communication requires language translation, the translation programs Rough 1 to Ware 9 operate the central processing unit 7 and convert it into the desired language. By the way, since the orbiting artificial satellite 1a is an orbiting satellite, it is unknown who the message is addressed to until it reaches the visible range of a specific usage station. , when the orbiting artificial satellite 1b and other multiple satellites are operating,
-The exchange of messages becomes complicated. However, the controller 1 of the repeater 24 mounted on the geostationary satellite 4
According to 3, the identification, title, etc. of the communication of each earth-orbiting artificial satellite, including the earth-orbiting artificial satellite 1a, is collected and organized via the wireless device]2, and conversely, each earth-orbiting artificial satellite is A series of lists of collected and organized messages are transmitted to the satellites 1a and 1). And each earth-orbiting artificial satellite 1
a and], b can have a common list of all communications).3 As a result, user 3 can know from any satellite which satellite has a message addressed to him. You can reliably receive messages addressed to you without having to be on standby 24/7.
尚、本通信に適する信号方式は特に限定されるものでは
ないか、特に効果があり、より実用的なものはデジタル
バケッＩ・通信方式である。。It should be noted that the signal system suitable for this communication is not particularly limited, and a particularly effective and more practical one is the digital bucket I communication system. .
