摘要：

The paper shows a preliminary feasibility analysis of a space project both economic and structural. The project consists of launching a new business for suppling near real time connection to EO LEO satellite through a bent pipe satellite constellation. The result of business analysis highlights a good return in the next decade which is acceptable for an innovative project in space market. Nowadays the target customer groups 146 satellites which could choose among three different kinds of subscription and pay between 10 and 20 euros per minute of downlink. The design constellation is created with experts' opinion: they have been interviewed with survey and analysed with AHP, which gives high relevance to listening window width. As concerns satellite platform, quite all of satellite subsystems have a TRL 9, for the remaining it has been destinated a large budget of research and development. Due to an estimation method of power and mass, it has been possible to evaluate the size of each satellite and the required power: satellite will have a dry mass of 25 kg approximatively and require 260 Watt of power. Due to details of each subsystem, it has been realised a 3D model with Catia v5 to visualize the satellite.
