The IoT (Internet of Thing) is widely used in variety terrestrial applications of industrial sector, socio-economic sector and service sector. Traditional MSS (Mobile Satellite Systems) and FSS (Fixed Satellite Systems) have developed M2M and IoT services. However, the new space is now covering a globally emerging private spaceflight industry, particularly satellite enabled IoT with low cost, low power, low latency, makes well suited for direct to satellite services. In addition, the expansion of the satellite constellations that allow for global connectivity. This paper presents an approach for space IoT net centric in LEO (low earth orbit) to enable IoT services over Thailand and South East Asia. The holistic system is designed from requirements-driven of downstream applications. The mission requirement and constraint are addressed. The bus system of 6U platform and IoT payload are designed. The constellation of 8 satellites in two orbital planes near equatorial orbit is proposed with simulated orbit tracking.
