The NET-G3A, incorporating Topcon's new Paradigm G3 chip technology, was the World's first reference receiver to provide Universal Signal Tracking – all signals from all three global satellite positioning constellations (GPS-GLONASS-Galileo). Using a unique and patented technology, the NET-G3A incorporates 144 Universal Tracking Channels that are capable of adaptively tracking a configurable mix of GPS, GLONASS and Galileo* signals. The NET-G3A receiver applies Topcon’s advanced signal tracking technology to deliver highly accurate and robust GNSS measurements on L1/L2/L5 frequencies --- providing the very best reference station solution on the market today.
