GNSS2 click™ carries Quectel’s L76 module that can receive both GPS and GLONASS signals.
Thanks to the east and west rivalry we now have two constellations of navigational satellites — the US Navstar of the GPS system, and the Russian counterparts that constitute GLONASS (acronym stands for Globalnaya Navigatsionnaya Sputnikovaya Sistema).
By being able to acquire signals from both, GNSS 2 click has double the number of available satellites, generally speaking.
What’s different compared to the first GNSS click, is that this one can work with a 5V power supply and logic level (as well as 3.3V). An onboard voltage translator enables that.
The L76 module features the same performance-enhancing Quectel technologies of the first GNSS click. Namely, automatic prediction of satellite orbits and adaptive on/off time that balances between positioning accuracy and power consumption.
Seems that the entire space race and the resulting invention of satellite navigation happened so that ordinary people wouldn’t get lost on their way to that newly opened shopping mall on the outskirts. Very kind thing to do of all those US and Russian scientists.
Now it’s your turn to develop gadgets that take advantage of all the space-age tech that’s at the tip of your left mouse click. Study the product details and the Libstock example which will get you started.
