GPS Receiver Rigged for Future Running

Topcon says its GR-3 receiver, with G3 GNSS technology built in, should give owners confidence that they have cutting-edge technology for the future and will not need to replace hardware as new satellite signals come on line. Topcon's G3 chip set can use all current and planned navigational signals from GPS and Glonass constellations, as well as signals from the European Union's planned Galileo satellites. The GR-3 also offers unique physical features: SD media for memory, SIM-card-activated GSM/GPRS cellular modem technology, multiple radio-modem options, and it can withstand repeated falls from a range pole.
