In 2015, OneWeb and SpaceX were developed as the Emerging Satellite Internet Constellation Projects among others. This paper reviews the development of the satellite internet constellation since the 1990s, and discusses the characteristics of different ones in different periods and the key factors that affect the success of the projects. This paper also makes an analysis of their advantages & risks on the context of the market positioning, the profit model, the satellite manufacturing, the satellite launching and the financing. The past failure lessons are used to evaluate the future new constellations. It is pointed out that the future development of emerging internet constellations will not simply repeat the past patterns. The emerging satellite constellations would have positive influences on the traditional satellite communication industry, the satellite operation, the satellite manufacturing and industry development concepts.
