The term “microsatellite” or “microsat” is usually applied to the name of an artificial satellite with a wet mass between 10 and 100 kg (22 and 220 lb). However, this is not an official convention and sometimes those terms can refer to satellites larger than that, or smaller than that (e.g., 1–50 kg (2.2–110.2 lb)). Sometimes, designs or proposed designs from some satellites of these types have microsatellites working together or in a formation. The generic term “small satellite” or “smallsat” is also sometimes used, as is “satlet”.
