Direct-to-Device Satellite IoT is a system where small satellites in Low-Earth Orbit (LEO) communicate directly with ground-based sensors or mobile phones, enabling data transmission without the need for intermediate ground stations.
Addressing the limitations of traditional satellite communication systems by reducing dependency on ground infrastructure, thus enhancing coverage in remote locations and providing reliable data transmission for applications like asset tracking and environmental monitoring.
Satellites in LEO orbit at altitudes between 160 and 2,000 kilometers, providing a wide coverage area. They relay short, low-power messages from unmodified or lightly modified devices to other satellites or directly to Earth-based receivers, extending connectivity to remote areas such as oceans, deserts, and rural regions.
The manufacturing process involves designing and building small satellites (CubeSats or smaller) capable of handling low-power communications. Components such as solar panels, batteries, communication antennas, and microcontrollers are assembled to ensure robust performance in space conditions.
Satellites undergo rigorous testing for thermal, vibration, and electromagnetic compatibility before launch. The build process includes component selection, assembly, integration, and final testing to meet the stringent requirements of LEO operations.
