## AI overview

This article presents working notes on receiving and interpreting data from the EU's Galileo Navigation Satellite System. It covers configuring a u-blox 8 receiver, enabling Galileo and relevant message formats, extracting raw I/NAV data from UBX-RXM-SFRBX messages, and understanding Galileo ephemeris parameters.

## Source excerpt

I've recently been spending quite some time on the EU's Galileo Navigation Satellite System. In this post you'll find some rough notes on things I've found out, both about how to receive data & how to understand the Galileo ephemeris parameters. Feedback is very welcome on bert@hubertnet.nl or @bert_hu_bert! I'm no Galileo specialist, so I am sure this page could be better. Please also let me know if this page has been useful to you.
