GR-3
Topconâ s GR-3 receiver, the next generation of system design and tracking technology, is now available with a completely new digital UHF radio system utilizing DSP technology. This technological advancement delivers far greater reliability and performance than older analog UHF technology of the past and sets new standards for performance, accuracy and innovative design.
GPS receiver design has taken a quantum leap forward with the new GR-3. It starts with 72 â universalâ channels that support all current and planned satellite positioning signals. Then thereâ s the micro-tuned, precision antenna capable of receiving all G3 positioning signals with Topconâ s patented center-mount radio antenna for superior signal tracking and interference reduction.
The GR-3 receiver incorporates a unique dual communication system, featuring both cellular and radio technology. Offering a 915 MgHz Spread Spectrum internal Tx/ Rx* or Digital UHF radio, the GR-3 can serve roles as either an RTK base or rover system. And by utilizing the optional internal GSM/ GPRS/ CDMA modem communication system via the easily accessible cellular SIM card slot, a user can extend their range far beyond radio capability or utilize both receivers as rover systems off a fixed base station or a network system.
* 915 MgHz Spread Specturm radio technology is not approved for use in Europe or Asia
