  "textContent": "The invention relates to a system for determining a swing boom angle 2 of an excavator 1, wherein the excavator 1 comprises a lower part 3, an upper part 4 comprising a cabin 5, the upper part 4 being arranged on the lower part 3 and configured to be rotated relative to the lower part 3 about a first rotation axis 7 and a swing boom 6 arranged on the upper part 4 and configured to be rotated relative to the upper part 4 about a second rotation axis 8 that an actual swing boom position defines a swing boom angle 2. The system comprises a first inertial measurement unit (IMU) 12 configured to be mounted on the swing boom 6 and to generate first IMU data, wherein the first IMU 12 comprises at least one acceleration sensor and a processing unit. The processing unit is configured to receive the first IMU data, determine a direction of a centripetal acceleration acting on the first IMU based on the received first IMU data when the upper part 4 rotates about the first rotation axis 7 relative to the lower part 3 and determine the swing boom angle 2 based on the direction of the centripetal acceleration.",
