Overview of Application Research on Inertial Navigation Unit

Abstract

We now widely used in the positioning and navigation system is the global positioning system, but the global positioning system is mainly suitable for outdoor navigation, empty place on the indoor navigation is less satisfactory. Therefore, the main content of this paper is the application of indoor positioning and navigation of inertial measurement unit. Firstly, the basic theory of inertial measurement unit (inertial measurement unit) and its current research status in navigation are reviewed. Then, relevant researches are analyzed and reviewed from the following aspects: its advantages and disadvantages, its combination with other positioning methods, and its application principle. At the same time, it points out the constraints and challenges of inertial measurement unit in navigation application, and puts forward the future prospects.
