Small satellites, often referred to as small sats, are compact spacecraft typically weighing less than 500 kilograms. They are designed for various purposes, including Earth observation, communication, and scientific research. Due to their smaller size, they are generally more cost-effective to build and launch compared to traditional larger satellites. These satellites can be deployed in groups, known as constellations, to enhance coverage and data collection capabilities. Their advancements in technology allow for improved performance and functionality, making them increasingly popular among governments, private companies, and research institutions for a wide range of applications.
