Determination of an excavator swing boom angle based on intermittent first interim swing boom angles

A system for determining a swing boom angle of an excavator, wherein the excavator comprises:

• a vehicle frame comprising a cabin,
• a swing boom arranged on the vehicle frame and configured to be rotated relative to the vehicle frame about a vertical rotation axis that an actual swing boom position defines a swing boom angle, wherein the vertical rotation axis is a vertical axis,
• wherein the system comprises:
• a first measuring sensor configured to be mounted on:
• the vehicle frame, or
• the swing boom,
• wherein the first measuring sensor is configured to determine a first interim swing boom angle of the swing boom relative to the vehicle frame about the vertical rotation axis, the first interim swing boom angle being one of a discrete amount of one or more intermittent first interim swing boom angles about the vertical rotation axis, each of the discrete amount of one or more intermittent first interim swing boom angles being spaced from each other by at least a value of one degree,
• a second measuring sensor configured to be mounted on the swing boom and to determine a second interim swing boom angle of the swing boom relative to the vehicle frame about the vertical rotation axis, the second interim swing boom angle being from an indiscrete angle range, a processing unit configured to:
• receive the first interim swing boom angle and the second interim swing boom angle about the vertical rotation axis, and
• determine the swing boom angle by applying at least one of a filter and an algorithm to the first interim swing boom angle and the second interim swing boom angle about the vertical rotation axis.
