Abstract:
In this paper, a precise investigation has been done on different types of constellations using for narrow-band communication from different aspects including coverage, orbital mechanics and constellation design for regional coverage. It means the first step in constellation establishment is architecture of it. The architecture of constellation determines number of satellite, and location of satellites to have more efficient coverage. There are wide varieties of options which are assumed as constellation to work effectively, but we have investigated in low cost symmetrical constellation with circular orbit to cover a zone. Here, we have studied arrangement of satellite in this specific type point, number of visible satellites for specific latitude are the main parts of this research for this type of constellations.
