INDEPENDENT METHOD OF DEFINING SHIP ACTUAL COURSE IN BASE WATER AREAS AND DEVICE TO THIS END Russian patent published in 2009 - IPC G01C23/00 

FIELD: physics, measurements.

SUBSTANCE: invention relates to defining the ship actual course in the base water basin. The proposed method comprises the steps that follow. The scanning (rotary) magnetic field with a preset rotary speed is induced at the first reference station. The module of the vector of induced magnetic field is measured at the second reference station, while the vector of induced magnetic field and its projection on the ship midplane direction are measured at the ship. The representative magnitude of the results of measurements of, for example, vector of the induced magnetic field module for a scanning cycle is defined for the interval of its measurement at the second reference point. The induced magnetic field magnetic moment is intermittently varied. The time interval between the moments of measurements of representative magnitude of induced magnetic field at the reference station and ship is measured at the ship and the magnetic field projection on the ship midplane direction is recorded. Now, the obtained data is used to define the ship actual course. The proposed method is embodied by the device designed in an appropriate way.

EFFECT: reduced time of getting ship navigation complex ready for operation and correction of ship course determined by above complex.
