Perspective on Pedestrian Inertial Navigation Systems

This chapter provides a perspective on further development of both the hardware and the software for pedestrian navigation. Hardware development for the pedestrian inertial navigation mainly aims to solve the problem of incorporating different sensing modalities with a reasonable size and weight, such that the overall system is compact, robust, and accurate. Software development for the pedestrian inertial navigation mainly aims to explore algorithms to fully use the collected data, in order to further improve the navigation accuracy and adaptivity without too much computational load. Cooperative localization can be achieved if multiple mobile agents are available in the network, with communication and computation capabilities, jointly processing a relative measurement between each agent to increase their localization accuracy. There are many ways to fully utilize the Inertial Measurement Unit data besides just integrating them into position estimation.
