The data communication demand on the Internet has been rapidly expanding and the terrestrial data communication bit rate has become extremely fast by the spread of broadband access lines such as ADSL. The data communication speed of 144kbps has been the highest in the field of the mobile satellite communication so far. INMARSAT launched the next generation satellites from the hope for further speeding-up of the data communication also in the mobile satellite communication in the future. In this article the outline of INMARSAT fourth generation satellite newly launched and BGAN service are described.

I am pleased to imagine that university students all over the world will jump with deep emotion when they hear a voice from their hand-made satellites. At the unforgettable moment upon receiving a signal, one student said that he felt impressed "as if tears were coming from each cell in his whole body." I believe that facilitating young people to experience such glorious moment leads us along a narrow path to a better future." Ms. Rei Kawashima, University Space Engineering Consortium, which was established to facilitate and promote practical space development activities in universities and colleges, describes her experience from the International Space University to student's micro-satellite projects such as CanSat and CubeSat..
