Zhelamsky M. V. The first domestic magnetic positioning system

Commissioning and startup results for the first domestic magnetic positioning system are discussed. The system is intended for measuring linear position and orientation of a moving object in the fixed coordinate system. It accomplishes two basic tasks: target search under minor linear displacement range, and navigation, i.e. measuring linear coordinates of an object moving away from its original position. The system structure and the communications between its components are described as well as its performance data and experimental results obtained at linear displacement of the receiver and its movement along a circular trajectory. The paper concludes about the necessity of  individual system calibration for attaining ultimate positioning accuracy. Future works to be executed after system startup are listed.
