Experiment on the inverse GPS based ultrasonic positioning system

摘要

This paper describes experiments on the of inverse GPS based ultrasonic positioning system. The principle of the inverse GPS based positioning system that the relationship between transmitters and receivers was proposed, however no that experiment has not been done yet. This paper describes that the experimental setup is manufactured by way of trial using ultrasonic transducer, an A/D converter, and a PC; experimental positioning is carried out in the region of 20-30 cm cube. Relationship between estimation errors and the GDOP is discussed.
