In summary, Furuno GT-86 and GT-87 series are high-sensitivity, high-accuracy GNSS/GPS chips and modules supporting positioning and timing solutions, enabled to receive signals of almost all GNSS Systems available. They also support dead reckoning (DR), and high positioning rate (e.g. 10Hz) for positioning. The GT-86/GT-87 support TRAIM and various position modes, allowing it to output accurate and robust 1PPS synchronized to UTC time as well as clock output functionality (configurable to, e.g. 10MHz). The GT-86/GT-87 supports GPS, GLONASS, QZSS, SBAS, Active Anti-Jamming and Advanced Multipath Mitigation functions. The output data is in NMEA or M12 (Motorola) Binary protocol.
