Topcon Positioning Systems’ GR-3 system Topcon Positioning Systems’ GR-3 system (a triple- constellation satellite receiver: GPS, GLONASS and Galileo — presently in its testing phase) now has a UHF digital radio option that covers a broad range of frequencies with greater distance than the spread spectrum option. The new UHF radio adheres to transmission guidelines for a wide range of RTK applications. The GR-3 has 72 universal channels that can track up to 36 satellites simultaneously and, says Topcon, uses a magnesium I-beam chassis and housing that can withstand a two-meter drop onto concrete. According to the company, the G3 chip is designed to receive all existing signals, plus all signals from planned satellite launches in the foreseeable future. Combined with Topcon’s new Pocket Layout software for construction, the GR-3 can be used for one-man layout projects.
