Sokkia GSR2700 ISX Base Rover RTK
The GSR2700 IS features simple single-button operation and LED indicators for battery life, satellite tracking status, remaining memory and integer fixed occupation time. Ease of use of the receiver is further supported by voice messages which indicate the receiver status during field operation. The receiver is light weight which together with ergonomic design and cable free operation results in less fatigue and increased productivity.
The GSR2700 IS was designed to fully profit the revolutionary SDR+ data collection software. With SDR+, the GSR2700 IS can be swiftly configured for static, kinematic and RTK use. Or take advantage of the system’s built-in EGNOS and WASS capability to provide real-time positioning without the need for a base station. Because of its flexibility, the GSR2700 IS can be set up for multiple configurations.
Features:
- Cable-free, lightweight and rugged
- Flexible and easy operation
- Multiple configurations
- Powered by new SDR+ data collection software
