Positioning & timing GNSS:
Introduction
GNSS
GNSS (Global Navigation Satellite System) is a system, which provides positioning and time synchronization capabilities to an unlimited number of users worldwide. The system is based on signals from the following four satellite constellations.
Signals from the different constellations can coexist on the same frequency bands. Each GNSS provides different signals and services over these frequency bands with different access policies. For example, open signals on the L1 frequency band are mostly used for civil commercial applications.
The application environment of the receiver plays an important role in the navigation, with best performance obtained in open-sky conditions. Presence of obstacles and multipath effects define a GNSS challenging environment (e.g. urban canyons), where the receiver has to work with fewer and weaker signals. This makes multi-GNSS even more decisive to the receiver’s performance, since more satellites are available for tracking in a given area.
