Low orbit LEO satellites (Low Earth Orbit) have become commercially relevant for providing low latency and high capacity broadband services as well as M2M communications and imaging. At a distance of 180-2000 kilometers from the ground, the LEO satellites are relatively inexpensive compared to the satellites passing through the MEO satellites (12000-36000 km) or geostationary track. In addition, they operate at a lower RF power.
Commercial pressures are now squeezing the satellite’s material costs, while operating costs are shrinking and attempts are made to improve reliability. Radiation-resistant analog-mixed signal circuits, along with radiation-resistant FPGA circuits with an integrated RISC-V processor architecture, helping designers meet their goals.
