Sky and Space Global (SAS) is the first company to plan, build and operate a telecommunication commercial network over Nano-Satellites. Following the successful launch of its 3 first satellite (the 3 diamonds) SAS plan to launch 200 satellites, providing equatorial coverage and beyond. The satellites are placed carefully in synchronized orbits that circle the earth almost every hour and half. The satellites communicate between each other and each satellite beams down to in a circular footprint. The constellation thus creates a mesh in the sky where each satellite serves as both as a base station and a router. SAS operates in the S-band frequency range that enables a very small device with patch antenna (8 cm) or monopole antenna and low power consumption. The network of SAS is a narrow band communication network suitable for IoT, M2M, personal voice and messaging. Their nano-Satellites are fully operational satellites with a mass of less than 10 kg. Due to miniaturization of technology, Nano-Satellites are capable of providing accurate altitude and orbit control and communication services. They showed us some low cost hotspots used to track and provide services to vehicles such as trucks for the transportation industry.
