Research Abstract	最終年度の平成15年度は、以下の研究計画に従って実施した。 (1)、全体会議(全員)及び開発会議 (2)、データ収録システム並びに実用化モデルの検査(河野、巻田、塩川、小沢、湯元) 昨年度の成果を元に、データ収録システムを設計した後、電源対策を施し、GPS計時装置を組み入れた、フラッシュメモリーカード(650Mbyte)を記録媒体とするCPU(消耗品費)によるシステムコントロールできうる省電力型の半自動観測記録システムを試作完成し、その性能を検査した。 (3)、実用化システムの製作・購入(小沢、吉川、湯元) 2に基づいて開発した仕様に従ってGPS付半自動観測記録システムを製作する為に備品(設備備品費)を購入した。 (4)、実用化システムの性能試験(河野、吉川、巻田、瀬戸、塩川) 210度磁気子午線沿いのシベリア、アラスカ、日本、オーストラリア等の36観測点、磁気赤道域で経度の隔ったブラジル、ペルー、西太平洋、ミクロネシア諸島の12観測点や北米の極冠からオーロラ帯の20観測点からなる観測網の中で、特に、国内の5観測点と設置環境の悪い観測維持の困難な海外観測1点に新しいGPS付観測記録システムを配備し、データ取得の安定度、データの精度等の確立の為の、実用化システムの性能試験(記録媒体等の消耗品費が必要)をした。 (5)、インターネット・衛星及び電話回線を用いた観測データのオンライン・リアルタイム取得の予備観測を行った。(吉川、塩川、河野、湯元)
