Claim 0:
1. A system for measuring a water-filled structure, the system comprising:
a measurement device comprising,
a sensor carrier with a first end arranged below a surface of water when the measurement device is in a state of use,
a second end arranged above the surface of water when the measurement device is in the state of use,
at least one measurement sensor arranged on the first end of the sensor carrier and configured to measure the water-filled structure by capturing measurement data, and
an acceleration sensor and a GNSS receiver configured to receive GNSS signals from satellites in a global navigation satellite system;

a tachymeter positioned outside of the water-filled structure and configured to be aimed at the measurement device; and
a control unit configured to determine at least one of: (1) a current position of the measurement device; and (2) an orientation of the measuring device, using measuring data from the acceleration sensor, the GNSS signals received by the GNSS receiver, and the measuring data captured by the tachymeter,
wherein the control unit is further configured to match the at least one of the current position and the orientation, to the measurement data.
