Topcon Releases New GR-3 Receives

Topcon Europe Positioning B.V. (The Netherlands) has introduced the new GR-3 system, an all-inclusive RTK GNSS satellite receiver for all existing and planned satellite constellations.

The GR-3 is designed to withstand a fall on a range pole (two-metres) and comes with a ‘bulletproof’ warranty to back it up.

GR-3 has 72 universal channels that can track up to 36 satellites simultaneously.

The GR-3 has a completely integrated, cable-free base and rover design. In addition to Paradigm G3 technology, the unit features:

• optional internal GSM/GPRS SIM card modem for cellular connectivity.
  
• ergonomic design includes a ‘quick-snap’ pole mount, reducing the likelihood of damage while affixing it to or removing it from the pole.
  
• dual, ‘hot-swappable’ battery packs, operation time more than 12 hours.
  
• an additional battery pack utilises off-the-shelf AA batteries.
  
• dual-function design–each unit can be a base or rover.

The GR-3 also has an optional cellular communication system with an easily accessible cell phone card slot. This capability extends the range beyond normal radio limits and provides increased functionality with RTK networks. Additionally, the unit is equipment with Bluetooth wireless technology for a completely cable-free operation with Windows CE field controllers and other compatible devices.
The GR-3 is powered by a lithium ion rechargeable battery pack mounted on the exterior of the unit for easy access. The batteries, which cover the SIM and SD Media Card slots, shield them from the elements; the batteries can be ‘hot-swapped’ during operation without loss of signal or position lock. An extra battery housing is included and accepts AA batteries for emergency operation, making the GR-3 the first RTK receiver on the market to accept off-the-shelf batteries.
