Cubesats

Definition

Cubesats are small, cube-shaped satellites that follow a standardized design, typically measuring 10 cm x 10 cm x 10 cm, and weighing about 1.33 kilograms per unit. They have revolutionized the field of satellite technology by providing a low-cost and versatile platform for various scientific and commercial applications. Their compact size and modular nature allow for easy integration and deployment in space missions, making them an increasingly popular choice for universities, research institutions, and private companies.
