The present project was planned based on the collaboration among GEOTAIL,WIND,AKEBONO,ULYSSES,Freja, POLAR,and INTERBALL spacecraft. However, due to the delay of the launch schedule of the POLAR and INTERBALL spacecraft, we proceeded the collaboration mainly among the GEOTAIl-WIND,GEOTAIL-ULYSSES,and AKEBONO-Freja spacecraft. The collaboration between the GEOTAIL and ULYSSES focused on the study on the interplanetary shock before launching the WIND spacecraft. The USLYSSES observations on the interplanetary shock near the Jupiter showed the good correlation with them by GEOTAIL near the Earth.On the collaboration between the GEOTAIL and WIND spacecraft, we paid our attention to the 2fp emissions, AKR emissions and Type III solar radio bursts. We successfully detected the source region of the 2fp emissions using the delay time of the observations between GEOTAIL and WIND.Further detailed study is continued using the more datasets.The AKR emissions are observed in the high frequency range beyond 100kHz. It is radiated in the polar region and its generation mechanism is closely related to the geomagnetic activities. We studied the propagation characteristics of the AKR using the GEOTAIL and WIND observations. The 2 point observations provide us the important information on the propagation of the AKR.We found the strong location dependence on the observations of the AKR.we checked the calibration of the receivers onboard the GEOTAIL and WIND spacecraft using the Type III solar radio bursts. We found the good agreement on the calibrated intensities of theirs.The plasma wave activities in the polar region were investigated under the collaboration between the AKEBONO and Freja satellites. We focus on the ion cyclotron waves observed in the polar region and discussed their generation mechanisms using the linear theory based on the observations by these 2 satellites which were located in the different altitudes.

本项目的计划是根据Geotail，Wind，Akebono，Ulysses，Freja，Polar和Blall Spacecraft之间的合作计划。但是，由于Polar和Enterball航天器的发布时间表的延迟，我们主要在岩土尾声，Geotail-ulysses和Akebono-Freja Spacecraft中进行了合作。在推出风航天飞机之前，Geotail和Ulysses之间的合作集中在行星际冲击的研究上。木星附近的尤里西斯对星际冲击的观察结果表明，在地球附近的Geotail与它们之间的良好相关性。在地球尾巴和风航空舰之间的合作中，我们注意了2FP排放，AKR排放和III型Solar Radio brounds。我们通过使用更多数据集的详细研究成功地检测了2FP排放的源区域的源区域。详细研究继续进行。在高频范围内，AKR排放量超过100kHz。它在极区域辐射，其发电机制与地磁活动密切相关。我们使用地球尾和风观测研究了AKR的传播特征。 2点观测为我们提供了有关AKR传播的重要信息。我们发现了强大的位置依赖于AKR的观测值。我们使用III III太阳能无线电爆发检查了Geotail和Wind spacecraft的接收器的校准。我们发现，在Akebono和Freja卫星之间的合作下研究了对它们的校准强度的良好共识。我们专注于在极区域观察到的离子回旋体波，并使用线性理论基于这2个位于不同海拔高度的观测值的线性理论讨论了它们的产生机理。
