A small satellite, often referred to as a small satellite or smallsat, is a type of spacecraft that typically weighs less than 500 kilograms. These satellites are designed for various purposes, including Earth observation, communication, and scientific research. Their smaller size allows for lower launch costs and quicker development times compared to traditional larger satellites. Small satellites can be launched individually or in groups, often as secondary payloads on larger rockets. They are increasingly popular among universities, private companies, and government agencies due to their versatility and accessibility. Many small satellites are equipped with advanced technology, enabling them to perform complex missions in space.
