A microsatellite, miniature satellite, or nanobot is a small satellite of very low mass and dimensions, typically under 200 kg. Although all of these satellites are described as "micro", different classification systems are employed to classify them based on size. Generally, larger satellites are classified in five categories. These are LEO (low earth orbit), MEO (medium earth orbit), STO (intersferable upper stage), and HEO (high earth orbit).

There are two types of nanosats: nanobots that are used in conjunction with scientific research and ones that are intended for general observance. The first type, the scientific research nanosat, is designed to gather data in different scientific fields, including astronomy, archeology, archeological science, astronomy, and genetics. It is often used as an additional probe. On the other hand, the operational nanosat, which is commonly used for communication, is made of materials that can withstand a low weight launch. It can transmit signals at a rate of between one to three megabytes per second. It has a size and design that allow it to maneuver and fit into tight places, such as signal aperture tubes.

As indicated above, there are two types of nanosats for use in a communication system. The smallsats are fitted into a communication system like a dish or a small satellite dish. The application of this technology depends on the market dynamics. For example, low-orbiting and medium-sized nanosats are used for communication between various centers, on the one hand, and a user on the other. In order to gain access to the market, a new satellite needs to be launched, either into orbit or onto a low-earth orbit.

The market dynamics determine which type of satellite will be used in order to meet the market's demands. There are many factors to consider, including availability, price, and features. Some nanosatellites are meant to function as communications tools for businesses. These satellites have to be very lightweight, flexible, and resistant to severe weather conditions. They may also have a dual purpose: serving as a small satellite for communication applications, and as a communications platform for collecting data, which could help form a market analysis.

Another type of nanosatellite is meant for remote sensing and imagery purposes. Since the market overview indicates the number of nanosatellites in service, the way in which these instruments will fit into the market should be determined. A microsatellite is only about five centimeters in diameter and has a maximum range of around ten kilometers. It is usually used for remote sensing of land and imagery. There is much less risk of collision with other satellites and of interference with the earth's biosphere.

Uses of Nanosatellite and Microsatellite 

Small nanosatellites are meant for surface research and survey applications. Most instruments in this segment have a fixed imaging sensor and a radio transmission antenna. However, there are some innovative instruments that use radio frequency transceivers, which can penetrate and acquire images of smaller shapes at greater distances than those that use cameras alone. Survey and investigation applications are a key driver for the growth of the nanosatellite business, especially in the field of surveillance and mapping.

When discussing market Overview, the next segment that needs to be addressed is the applications that nanosatitude technology development could support. The market continues to develop with ever increasing sophistication of instruments, sensors, antennas, and communications technologies. The main categories under which the market is developing are:

Global nanosatellite capacity and consumption will continue to grow as the demand for imaging and surveying applications increases. The primary drivers of this growth are the need to address the need for upgraded equipment in areas currently inaccessible; the need to monitor the Earth from space; the need for better maps and terrain measurements for scientific research; the need to improve surveillance over oceans, atmosphere, and land; the need for telecommunications in outer space; and the need to track and locate on Earth. These needs will drive growth over the next few years in the nanosatellite market. There are also other secondary driver factors such as the effect of inflation on the demand for bandwidth, the impact of tourism on tourism, political stability and security, and the aging of the Western consumer.
