Topcon GR-3 RTK satellite receiverTopcon's GR-3 RTK GNSS satellite receiver can capture signals from GPS, Glonass and the European Union's upcoming Galileo system. Topcon says the GR-3 will withstand a fall from a range pole and backs the system with a "bulletproof" warranty. Other features include a two-watt 915+ internal radio for interference-free RTK communication, optional internal GSM/GPRS SIM card modem for cellular communication, battery packs that operate to 12 hours and dual-function design (each unit can be a base or rover).
