 # Specific characteristics of Galileo: let's go further!
 
-Galileo broadcasts its signals on 3 different bands: _E1_, _E5_ and _E6_. The satellites are distributed over 3 orbital planes inclined at 56% of the equatorial plane. Each orbit has 8 active satellites and 2 back-up satellites. Galileo will also offer a more in-depth service called the High Accuracy Service. This service will use the two frequency bands of the "classic" open service plus an additional band from 1260 to 1300 MHz. The accuracy of this service will be of the order of 20cm horizontally and 40 cm vertically.

Whe can also talk about OSNMA (Opinion Signal Navigation and Mission Analysis) which is a navigation system for Galileo, the European global positioning system. It is designed to provide high-accuracy navigation information and mission data for Galileo users, including land and maritime navigation systems, transport applications and professional users. OSNMA uses high-performance navigation signals to improve the accuracy, availability and integrity of navigation information for end users.
