Signal monitoring for Global Navigation Satellite Systems (GNSS) consists of monitoring and analysing the signals emitted by these satellites in order to provide an accurate position and synchronised time. To do this, it is necessary to have a GNSS receiver that can receive and decode these signals.

# **Main principles of GNSS signal monitoring:** ### **Main principles of GNSS signal monitoring:**
* **Triangulation:** The basic principle of GNSS is triangulation, which consists of determining the position of a receiver by using the travel times of signals from several satellites. * **Triangulation:** The basic principle of GNSS is triangulation, which consists of determining the position of a receiver by using the travel times of signals from several satellites.
* **Time synchronisation:** GNSS signal monitoring also involves synchronising the receiver time with the satellite time, which is accurate to a fraction of a second. * **Time synchronisation:** GNSS signal monitoring also involves synchronising the receiver time with the satellite time, which is accurate to a fraction of a second.
