## Synopsis

The objective of this document is to present the [ESA](https://www.esa.int/) Technology Tree, which provides a classification system for all technical knowhow that is available in [ESA](https://www.esa.int/).

The Technology Tree has a three-level structure. The first level of decomposition introduces 26 Technology Domains (TDs). The TDs are then further subdivided into Technology Subdomains (TSs) and Technology Groups (TGs), as appropriate.
