GRX1 Scalable GNSS System

The GRX1 GNSS receiver features:
- Fully upgradeable, dual-frequency, 72-channel GPS+GLONASS receiver;
- Triple wireless technologies - digital UHF radio (Rx/Tx), GSM/GPRS modem and Bluetooth module are available as integrated options. This allows an array of data communication choices for RTK correction, both at a base station and at a rover;
- Voice messages notify the users when RTK is fixed or lost, along with other notifications, eliminating a need for repeated visual checks of the controller display; and
- Advanced data storage capability via SD and SDHC memory cards.

The SHC250 data collector features:
- Windows Mobile 6.5 OS;
- 806MHz XScale processor;
- 256MB SDRAM / 1GB Flash memory;
- 3.7 in. VGA touch-screen display;
- Built-in Bluetooth wireless module;
- IP66 dust- and water-protection; and
- SD/SDHC card slot / CF card slot.

The new controller software, Spectrum Survey Field, and the comprehensive GNSS software, Spectrum Survey Office, will also support existing Sokkia GPS receivers.

"This new GNSS system provides unmatched versatility and usability in RTK, network RTK and static applications that require millimeter or centimeter positioning accuracy," Denny Welch, senior vice president and general manager, Survey Business Unit, said.

The new Sokkia GNSS system will be available in early 2010.
