Global navigation satellite system used in real time kinematics.
In the photo, the receiver is mounted on a tripod and a tribrach (the leveling base). This setup suggests it is currently acting as a "Base Station." 1. The Base: It sits over a known point and stays perfectly still, receiving signals from satellites.
2. Correction: Because satellite signals can be slightly distorted by the atmosphere, the Base calculates the error.
3. Transmission: It sends "correction data" via the radio antenna (the black whip hanging down) to a second, mobile unit called a "Rover" carried by a surveyor.
4. Result: This allows the Rover to achieve incredible accuracy—often within 1 to 2 centimeters.
