Beschreibung
Zusammenfassung:	A system for proximity sensing on a marine vessel includes a main inertial measurement unit (IMU) positioned on the marine vessel at a main installation attitude and a main location, a first proximity sensor configured to measure proximity of objects from a first sensor location on the marine vessel, and a first sensor IMU positioned on the marine vessel at the first sensor location and at a first installation attitude. A processor is configured to receive main IMU data from the main IMU and first IMU data from the first sensor IMU, wherein the main location of the main IMU on the marine vessel is known and at least one of the first sensor location and the first installation attitude of the first sensor IMU are initially unknown, calibrate the proximity measurements based on the main IMU data and the first IMU data, and output a calibration completion alert.
