Everything you wanted to know about how Global Navigation Satellite Systems (GNSS) work

ESA Navipedia

Satellite navigation is progressing swiftly, in fact so swiftly that its printed textbooks can’t keep pace – so ESA has introduced its own wiki-based information source, Navipedia, which is also the first ever ESA technical wiki opened to the public. 

Who wrote it?

Written and reviewed by experts, there are more than 400 articles on the site to date covering the fundamental principles of satellite navigation, how receivers operate, the various systems in current or future operation around the globe and GNSS-related services and applications.  

Who will write it in future?

External contributions to the wiki, using the template form "What I know is", are actively encouraged - all submissions will be reviewed by an expert editorial board to ensure that technical information provided is always reliable.

Who's it for?

Navipedia articles have been classified into three categories: basic, medium and advanced, with target audiences ranging from highly knowledgeable GNSS specialists to the general public.
