Main objectives of this project were to do colaborative expeiments with an ionospheric heating facility HIPAS (High power active stimulation) near Fairbanks, Alaska, which is operated by UCLA, using our satellite Akebono, and another colaborative experiment with the U. S. scientific satellite DE-1.During these two years, we have been able to achieve successful results by the HEPAS experiments, but not able to get fruitful result by the DE-1 project, due to several unexpected situations of the satellites. During the last half year in 1990, we also made colaborative experiments with an ionospheric heating facility near Tromso in Norway.HIPAS is a high power HF radio transmitter (2.85 MHz and 1 MW) to heat the ionosphere. We have modulated the HF radio wave with a VLF frequency. As the result, an ionospheric current of the VLF frequency flows in the heated ionosphere, which radiates a VLF radio wave upwards and downwards. We have tried to observe this VLF radio wave by using our satellite Akebono and a receiver on the ground. In August, 1989, we succeeded to detect the VLF signal associated with HIPAS ionospheric heating on the ground by a VLF receiver 35 km away from the HIPAS. Satellite observations were not successful. We could successfully detect this VLF signal with Akebono at 2,300 km of altitude on November 28, 1989 and at 10,000 km on June 18, 1990 as well as on the ground.In November, 1990, we have made similar colaborative experiments with the Tromso ionospheric heating facility in Norway. The experiment on November 18 was successful for a satellite altitude of 1,200 km. As mentioned above, our joint experiments were satisfactory, in order to clarify the mechanism of VLF wave radiation from the heated ionosphere and the mode of propagation to the space and to the ground.

本项目的主要目的是利用我们的Akebono卫星，与美国加州大学洛杉矶分校在阿拉斯加州费尔班克斯附近的一个电离层加热设施HIPAS（高功率有源刺激）进行合作实验，并与美国的另一个合作实验。S. DE-1科学卫星。在这两年中，我们的HEPAS实验取得了成功的结果，但由于卫星的几次意外情况，DE-1项目未能取得丰硕成果。在1990年下半年，我们还与挪威特罗姆瑟附近的一个电离层加热装置进行了合作实验，HIPAS是一个用于加热电离层的高功率高频无线电发射机（2.85MHz，1 MW）。我们已经用甚低频频率调制了高频无线电波。因此，极低频频率的电离层电流在加热的电离层中流动，其向上和向下辐射极低频无线电波。我们试图通过使用我们的Akebono卫星和地面接收器来观测这种甚低频无线电波。1989年8月，我们在距HIPAS 35公里的甚低频接收机上成功地探测到了与HIPAS电离层加热有关的地面甚低频信号。卫星观测没有成功。1989年11月28日和1990年6月18日，我们分别在2, 300 km和10, 000 km高度的Akebono和地面上成功地探测到了这个VLF信号，1990年11月，我们与挪威的Tromso电离层加热装置进行了类似的合作实验。11月18日的实验在1,200公里的卫星高度上取得了成功。如上所述，我们的联合实验是令人满意的，以澄清甚低频波从加热电离层辐射的机制和传播到空间和地面的模式。
