Compared to the non-compensated (100) VRG with uniform radial width, the smaller frequency split (Δf) of 9 Hz was obtained in the compensated one with non-uniform radial width and optimized suspending beams in simulations. By using electrostatic tuning with multiple electrodes, we realized mode-matching in the as-fabricated compensated VRG with Δf of 126 Hz. Then, considering the dimensions, parameters of read-out circuit and mode-rotation caused by electrostatic tuning, a theoretical model of scale factor is derived. This model adequately considers effect of mode-rotation and dimensions on scale factor of a VRG, especially its radial width, ring radius and capacitance gap, which well explained the reason for the measured values of scale factor and bias stability.","PeriodicalId":244190,"journal":{"name":"2020 IEEE International Symposium on Inertial Sensors and Systems (INERTIAL)","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121633393","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper analyzes the influence mechanism of EGE on precession angle (θ) drift and proposes a simple novel method of EGE compensation for whole-angle mode CVG. It is demonstrated that this method can compensate EGE and characterize the damping asymmetry of CVG with high Q factor (million-order) conveniently. Additionally, the drift of the precession angle can be effectively suppressed after compensating EGE. Finally, the approach in this paper is also widely applicable to other inertial sensors equipped with multielectrodes, which may be useful for further researches on inertial sensors with high accuracy.","PeriodicalId":244190,"journal":{"name":"2020 IEEE International Symposium on Inertial Sensors and Systems (INERTIAL)","volume":"72 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117152151","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The idea is aiming at unfolding inertial sensors’ signal processing domain to the customers for integrating external information into the inertial sensor’s signal processing part to improve the performance of the inertial sensors and the integration system. The implementation of the software-defined gyroscope (SDG) reported in this paper is the first attempt to use the software architecture to process the signals inside the inertial device. Such a structure would bring lots of benefits, including performance improvement of inertial sensors and flexible signal processing parameter adjustment. By employing the Allan Variance method, this paper reveals the relationship between the signal processing process and the random characteristics of inertial sensors, which is critical for applications such as GPS/INS integrated systems. We show that different signal processing strategies would result in different stochastic error characteristics for the inertial sensors. Thus, we believe that the contribution of this paper can be good guidance for more advanced integrated system designs using software-defined inertial sensors.","PeriodicalId":244190,"journal":{"name":"2020 IEEE International Symposium on Inertial Sensors and Systems (INERTIAL)","volume":"71 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123270021","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Our approach enables, for the first time, the fabrication of curved electrodes at the micro-scale. The SiS device provides large overlap area and nearly uniform gap with large capacitance for better frequency tuning capability, reduced operating voltages, improved capacitive sensitivity and reduced temperature sensitivity as compared to other electrode architectures.

The developed method is a fast, direct and memory-efficient approach to the problem. The method uses statistical information from the time series of gyroscopic sample data and combines it with the desired fractional accuracy of the gyroscopic offsets. We show that by using the statistical information contained in the time series the process of calculating the gyroscopic offsets can be significantly optimized. We applied the method proposed in this paper to existing data used in generic algorithms. We have been able to speed up the calibration of gyroscopic offsets significantly. For the data used to benchmark against in this publication our proposed algorithm was about 50 times faster. The method also works on-the-fly in that the statistical information needed is updated every time a new measurement is available. This implies that our suggested method is also very memory efficient making it especially useful when re-calibration needs to be done often or on-chip. We have developed and published a C/C++ code which enables the application of our method to various possible application scenarios.","PeriodicalId":244190,"journal":{"name":"2020 IEEE International Symposium on Inertial Sensors and Systems (INERTIAL)","volume":"72 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127358824","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
