Abstract

Inertial sensors have found widespread use in various applications. Recently, we have proposed an inertial navigation system based only on Micro-Electro-Mechanical Systems (MEMS) technology. The motivation for implementing such a system was to determine with high accuracy the user position inside a building without the use of any additional systems or infrastructure. In this paper we propose a compensation method for the gyroscope angular rate data based on the ambient temperature. As a result, the errors were reduced while the accuracy of the system increased. Furthermore, by using an additional barometer sensor, the navigation solution can be computed in 3D coordinates.
