研究遂行のため主たる研究者3名が東京に集まり打合わせを行った．ここでは，役割の分担，研究の進め方について意見を交換した．また，ブイを遠洋に敷設する場合衛星通信が必要となるが，現在使われている技術試験衛星「きく８号」が運用停止間近であるため，商用の衛星通信の導入が必要であることが認識された．そのため，このような商用衛星を運用している会社を訪問し，商用の衛星通信の導入について技術的な面と経費の面からの情報交換を行った．続いて，関係者全員が集まり研究遂行の詳細な検討を行う必要があったが，別途基盤研究（S）の申請が行われていることから，結果がわかる5月末以降に実施することとした．データ解析においては，前年度に他経費によって実施した実験について得られたデータを整理するとともに，その意義や今後の研究への取り込み方等について検討を行った．この実験では，GNSSブイからの衛星通信によるデータがしばしば途切れることから，その原因はブイの揺動による通信アンテナの傾斜によってブイからの送信信号のゲインが低下するためではないかと考え，衛星通信用アンテナをブイが揺れても水平を保てるようなジンバル機構をもった治具に搭載して実験を行った．実験は弓削商船高専保有の2隻の船舶によって行われ，導入した機構が有効に働くかどうかの検証を行った．得られた結果を検証したところ，船舶の固有周期により，有効に働く場合と，必ずしもそうでもない場合があることが判明した．このジンバル機構を今後活用するためには，ブイの揺動の固有周期を明らかにしたうえで，デザインをよく考える必要があることが判明した．これらの研究成果について5月の地球惑星科学連合の年次大会において発表を行った．その後，別途申請していた基盤研究（S）が採択されたことから，関連研究者による全体集会を含め，研究の遂行を停止し，残金を返還することとした．

In the study, three researchers were involved in the research and development of the aircraft. in the study, three researchers were involved in the study, and three of the researchers were involved in the research and development of the aircraft. in this study, three researchers were involved in the research and development of the main satellite communication system in Beijing, which was conducted in Beijing, the main research team was involved in the study, and now the application of the technical and technical equipment of the satellite, the satellite and the satellite. For commercial satellite communications, it is necessary to carry out research on the necessary equipment for commercial satellite communications. For commercial satellite communications, for example, for commercial satellite communications, for example, for commercial satellite communications, for example, for commercial satellite communications, for commercial satellite communications, for example, for commercial satellite communications, for commercial satellite communications, for example, for commercial satellite communications, for example, for commercial satellite communications, for example, for commercial satellite communications, for commercial satellite communications, for example, for commercial satellite communications, and for commercial satellite communications. In the other way, we applied for the application of the system, and the results showed that the system was applied at the end of May. In the previous year, the application was completed in the previous year. In the previous year, the application was completed. In the future, it means that in the future, you will be able to collect the information from the employer and other users. GNSS satellite communications do not send messages, do not send signals, do not send messages, do not send signals, do not send signals, The equipment used for satellite communication is used to maintain the level of equipment and equipment for satellite communication. the equipment is equipped with the equipment, and the merchant ship is high enough to maintain the operation of the ship, and the equipment is installed in the vehicle. The ship has an inherent cycle, and the ship has a cycle. If there is a contract, it is necessary to determine that the machine is in active use in the future, and that the inherent cycle of the operation cycle will be clear. It is necessary to verify that the results of the research have been completed in May. After the annual meeting of the Earth Science Association, please apply for the basic research (S) of the scientific association of the earth. After that, you will apply elsewhere for the basic research (S), and the researchers will be invited to attend the whole meeting. The research will be stopped and the residual money will be returned.
