Topcon’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 “universal” channels that support all current and planned satellite positioning
signals. Then there’s the micro-tuned, precision antenna capable of receiving all G3 positioning signals with Topcon’s
patented center-mount radio antenna for superior signal tracking and interference reduction.
The GR-3 receiver also
incorporates a unique dual communication system, featuring both cellular and radio technology. Offering a 915 MgHz Spread
Spectrum internal Tx/Rx radio*, the GR-3 can serve roles as either an RTK base or rover system. And by utilizing the optional
internal GSM/GPRS 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
It
is the World’s First G3 (GPS, Glonass, Galileo) capable GNSS receiver, and a clear indication of
Topcon’s technology
leadership in the satellite positioning industry!
- Advanced Rugged System Design
- Optional Internal GSM/GPRS Cellular Communication
- 72 Universal Tracking Channels
- Bluetooth Wireless Technology
- G3 Satellite Tracking (GPS, Glonass, Galileo)
Rugged magnesium I-beam construction for unbeatable strength
& durability, the GR-3 also boasts easily accessible SD card memory and dual hot-swappable batteries for unlimited continuous
operation. Internal Bluetooth wireless technology provides GR-3 users with the advantages of a completely cable-free system
with any Topcon field controller.
Topcon's GR-3 with its wide array of advanced design features
is truly a revolutionary receiver– two steps ahead of any other receiver technology available!
