8.10 SemiDyna

Due to the influence of crustal movement, the actual position of the reference point used for measurement on Earth will deviate from the coordinate values represented by the measurement results over time. In order to maintain the unified accuracy of position information (latitude, longitude, elevation) for a long time, [SemiDyna] can correct the distortion caused by uneven crustal movement during the measurement calculation process.
