What is GNSS ?
Global Navigation Satellite Systems (GNSS) means a system of satellites which broadcast signals from space with positioning and timing information. These signals are picked up by trackers which has embedded such signal receivers. The tracker then use this information to determine their geographic location in terms of longitude, latitude and/or height.
Multiple GNSS Receiver in Trackers
Generally, trackers embody a chipset good for all or multiple GNSS. It receives transmissions and data from the systems as the chipset supports to. Users have not troubles in optioning among the systems even you don’t have much knowledge of them.
Why multiple satellite systems?
Embodying receivers of multiple systems allows a tracker accessing to the information from different systems and more satellites. The multiple GNSS constellations increases the availability to track despite the uncertain factors like signal jamming, spoofing or geo-political unrest. Tracking with multiple system reduces the risk of depending on one system alone.
