Abstract:

In complex scenes such as combat and disaster relief, it is difficult to obtain external signals and locate. Due to its characteristics, inertial system has become an indispensable method of autonomous positioning in complex scenes, but there exist accumulated errors for inertial devices, which cannot meet the requirements of long-range positioning accuracy. Ultrasonic ranging is less influenced by the environment and has a low cost, which has become an important way to assist inertial devices in pedestrian positioning. At present, inertial and ultrasonic combined navigation are mostly theoretical research and simulation verification, and a small number of realizable systems are not convenient for subsequent research and experiments. In view of the above problems, a double full binding positioning system is realized based on Mti-G710 micro-electromechanical systems (MEMS) of Xsens company and DJIN1002 ultrasonic module of DAKOTA company, and field tests are conducted to verify the feasibility of the system.

Key words: double feet munted, micro-electromechanical system (MEMS), ultrasonic module, pedestrian positioning, system implementation
