Headline Details: A 50kg microsat with two missions:(1) Mission: BBS service Exchanging messages between amateurs all over the world in amateur service. Any amateur can use the space station like a BBS by uploading and downloading messages. The specific steps includes: An amateur radio station transmits messages to the space station for individual/public and these messages are stored in the space station. Another amateur radio station transmits a specific message to the space station and the space station transmits a reply message whether any message to him exists or not. If exists, the amateur radio station can receive the message by transmitting a specific message to the space station. Frequency band: - UPLINK : 435-438 MHz - DOWNLINK : 145-146 MHz (Note:The usage of the BBS is shown in the following URL.
