Measurement of MEMS gyroscope parameter changes
Raichl, Petr ; Beneš, Petr (referee) ; Kunz, Jan (advisor)
The thesis is aimed on determination of parameters of MEMS gyroscopes with Allan variance. In the introduction, there is principle of gyroscopes described. The first part describes deterministic and stochastic parameters. Methods for determining these parameters are also described. In the practical part, stochastic parameters of two gyroscopes are determined with Allan variance. In the next part, thesis describes determination of changes of stochastic parameters after vibrations and shocks.

Modeling of Inertial Sensors
Trličík, Jakub ; Klusáček, Stanislav (referee) ; Beneš, Petr (advisor)
This master thesis deals with measurement and modeling of MEMS inertial sensors. This paper describes basic principles of inertial sensors along with their most often errors. The next part shows results from inertial sensor market analysis, which enabling a selection of sensors to be measured. The following two chapters present methods for inertial sensor modeling and testing. The biggest part of text is dedicated to presentation of measurement results showing us static measurement of Allan variance, Earth rotation, temperature dependent bias and dynamic measurement of gyroscope sensitivity testing over temperature. In the last part of the thesis is presented a design of sensor error model by autocorrelation function and Allan variance and also an evaluation of achieved results.
