Tohoku University Technology: Satellite positioning method, device, system and construction equipment: T19-444
Positioning process continues even if the object posture is changed
Currently, satellite positioning method using signal emitted from satellite is known to determine the location of an object. Construction equipment such as backhoe and dump truck changes its position and posture. For example, a dump truck changes its posture with the angle of his cargo bed change. As a result, construction equipment with such changing position and posture may not be able to continue the position determination process. This invention is able to continue the process of determining one object's position even if this object changes its posture. In determining the position of an object using signal emitted from satellite, the invention determines the position of the object without using signal emitted from invisible satellite that may not be able to receive direct waves when the object's posture changes. This improves the accuracy of position information even when one object's posture changes.
