What are the advantages of nanotechnology satellites?

Nano-satellite adopts multiple integration technology in micro-electromechanical integration system, and uses the design idea and manufacturing process of large-scale integrated circuit to integrate not only mechanical components such as electronic circuits, but also electrical and optical systems such as sensors, actuators and microprocessors in a very small geometric space, forming electromechanical integration satellite components or subsystems with specific functions, making the devices light, solid and reliable, thus having more advantages;

(1) The satellite is reconfigurable.

(2) The distributed constellation structure can greatly improve the survivability of satellites.

(3) Nanosatellites are light in weight and can be launched without using large vehicles, and their cost can be greatly reduced compared with ordinary satellites.

(4) Distributed constellation structure, which can be transmitted many times.

(5) The development of nanosatellites will no longer need large-scale experimental facilities and long-span workshops, but can be carried out in laboratories of universities and scientific research institutes, which brings great convenience to the development work and reduces the development cost.

Take integrated circuits as an example. 16 trillion chip produced in 1992 has an integration of 32 million components and a line width of 0.5 micron, that is, 500 nanometers. The 64-megabit chip produced later has a line width of 0.3 micron, that is, 300 nanometers, and the integration level can reach1280,000 components; At the end of the 20th century, a 1000 megabit chip appeared, with a line width of only 100 nanometer and an integrated height of 20 billion components. 2 1 century, entering the nano-space, the integration will reach 2 trillion elements, and the line width will be 0. 1nm. If satellites are made of such products, there will be a revolution in space technology.
