Abstract

This document describes minimum requirements for small spacecraft.

This document covers different categories of small spacecraft – so-called mini-, micro-, nano-, pico- and femto-, as well as CubeSat, spacecraft. Therefore, for the sake of convenience, the term “small spacecraft” is used throughout this document as a generic term.

This document can be applied by small spacecraft developers, as well as dispenser providers and launch operators.
