Have you ever wondered what the difference is between GPS and GNSS<\/strong> or how smartphones, drones, and professional instruments determine position accurately? In this guide, we\u2019ll explain clearly and simply how satellite positioning systems<\/strong> work and why it\u2019s worth using multi-constellation receivers.
\nYou\u2019ll discover what RTK technology is, which factors influence survey accuracy, and why using devices like ProTRACK<\/a><\/strong> can make the difference in topographic, agricultural, and industrial fields. In the end, you\u2019ll know how to choose the right technology to obtain reliable data<\/strong> and precision even in difficult conditions.\n<\/p><\/blockquote>\n

Every time you use a car navigator, check your drone\u2019s location, or track a delivery package, you\u2019re using incredibly advanced technology: satellite navigation<\/strong>.
\nBut have you ever wondered how it really works? And more importantly, do you know what the difference is between GPS and GNSS?
\nIn this guide, we\u2019ll explain everything you need to know about these systems and also show you how to choose the best tools to get maximum accuracy, such as the ProTRACK<\/a> receiver.<\/p>\n\r\n\r\n<\/a>\n

GPS: The Global Positioning System (and beyond)<\/h3>\n

GPS (Global Positioning System) was developed in the United States and is one of the first and most widely used satellite positioning systems.
\nIt was created for military purposes, but today it\u2019s used by billions of devices around the world, from smartphones to smart tractors.

\nHow does it work? Very simply: your device receives signals from at least 4 GPS satellites, and through a calculation called trilateration, it can determine your precise position<\/strong> on Earth.

\nGPS has revolutionized how we orient ourselves, but today it\u2019s no longer the only system available.<\/p>\n

GNSS: A Broader Vision of Satellite Navigation<\/h3>\n

The term GNSS (Global Navigation Satellite System) refers to all existing satellite positioning systems, not just GPS. In addition to the American system, there are also:<\/p>\n
