RTK GPS survey equipment is the latest technology available in surveying. This equipment uses a real-time kinematic (RTK) global positioning system (GPS) to locate measurements and important points with less effort and more accuracy.For RTK survey we need two GPS Receivers. one for base other for rover. In here i describe it with photos.
- without external radio unit we are limited to 150m for signals.
- SATEL radio unit powered. and connect the antenna with SATEL radio unit.
- connect the base GPS receiver and radio unit. and also powered the receiver from car battery.
