A constellation of nanosatellites is a group of very small satellites, usually weighing less than 10 kg, that operate together to accomplish a specific mission. Nanosatellites are generally cheaper to manufacture and launch into orbit than traditional satellites, making them an especially cost-effective option.

Constellations of nanosatellites can be used for various applications such as environmental monitoring, communication, navigation, and mapping. They can also be used to study space and the solar system, provide Internet coverage in remote or underserved regions, or for space logistics applications.
