Articles about what you want nanosatellites to do.

The concept of nanometer was first put forward by American scientists in 1995. Scientists classify satellites into many categories according to their weight, including1000kg large satellites,100kg small satellites, and10kg-100kg micro satellites.

First of all, the development cost of nanosatellites is low. At present, the average development cost per kilogram of satellites is $80,000 ~ $65.438 billion. The launch cost per kilogram of satellite is 2 1400 USD. To develop and launch a satellite with a mass of 1000 kg requires at least1000 million US dollars, while the cost of a nanosatellite is less than1000 million US dollars. Secondly, the development cycle of a nanosatellite is short. At present, the development cycle of a large satellite is about 10 years, while the development of a nano-satellite only takes two or three years. This is more suitable for the era of rapid development of technology. Third, nanosatellites not only save launch and recovery costs, but also save orbital space. Fourth, nanosatellites can give full play to group advantages. Scientists are designing constellations made up of small satellites, whose functions make many big satellites cringe. Develop high-frequency, high-speed, broadband low-altitude orbit constellation system and build a spatial information superhighway. It will become a hot spot in 2 1 century, because it is cheaper and easier to build than optical fiber communication, and it is the main force in the information age. If 648 nanosatellites with different functions are arranged at equal intervals in geosynchronous orbit, it can ensure all-weather and all-day monitoring of any point on the earth.
