The approach is alternative to the conventional one when an INS-type AHRS is used to provide attitude and heading data in order to transform the velocity components to the geographical frame. The new approach which was named Indirectly Correctable Pendulum (ICP) uses two techniques: one — is the construction of one-channel inertial vertical based on two vector observation. In doing so one vector is the specific force vector and the vertical is constructed in the plane that contains true vertical and the second vector regardless of its nature. The natural frequency of the inertial loop is defined by the nature of the second vector and can differ from the Schuler one. The second technique includes the compensation of the motion induced disturbances in the tilt angles generated from the accelerometer outputs but provided in the position components using the log data and the motion acceleration component generated in the inertial vertical channel. As a result the higher navigation accuracy and/or the reduced amount of gyros as compared to the conventional solution can be achieved.","PeriodicalId":237642,"journal":{"name":"2018 IEEE International Symposium on Inertial Sensors and Systems (INERTIAL)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125877208","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}

Piezoresistive accelerometer is one of the wildly used types of sensor on the market with normal air package. However, when it is used in high impact environment, its fragile sensitive parts might get damaged. In this paper, we tried to use non-conducting liquid instead of air to fill the package shell of piezoresistive accelerometer. Its sensitivity and measuring range were analyzed when the package shell was filled with glycerinum, cyclohexane and silicon oil, respectively. Its resonant frequencies with glycerinum, cyclohexane and silicon oil package were also analyzed. The conclusion is that the liquid package is more suitable than air package for the piezoresistive MEMS accelerometer in harsh environment.","PeriodicalId":237642,"journal":{"name":"2018 IEEE International Symposium on Inertial Sensors and Systems (INERTIAL)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129883389","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 stations, specifically designed and assembled, are equipped with a triaxial MEMS accelerometer, and gyroscope and GPS. In this paper we present the characteristics of the station and of the network.

Inherently matched SAWGs were built on Y-cut Lithium Niobate (LN). Differently from all prior SAWG demonstrations, a large mass formed by periodically placed Au pillars were made to vibrate in-plane (and not out-of-plane) so as to measure rotation orthogonal to the gyroscope surface. Two cavity sizes were investigated. The larger cavity SAWG provided better performance. The experimental data agree well with theoretical expectations, hence validating our models.","PeriodicalId":237642,"journal":{"name":"2018 IEEE International Symposium on Inertial Sensors and Systems (INERTIAL)","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129714029","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}

It is shown how, even with discrete electronics, it is not trivial to isolate this contribution from electronic-related components, due to unavoidable electronics tolerances and drift. A method that involves the use of multiple (at least two), nominally identical boards, pre-characterized in terms of temperature drift, is shown to be effective in identifying sensor-related drift components with an accuracy as low as sub-50 μg/K. At the same time, the developed board reaches high-resolution performance, in order to clearly highlight the Brownian noise limit (40 μg/√Hz) in the tested consumer-grade accelerometers.","PeriodicalId":237642,"journal":{"name":"2018 IEEE International Symposium on Inertial Sensors and Systems (INERTIAL)","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130807192","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 manuscript mainly focuses on low-power architectural aspects, on the sensitivity of the transduction principle against process and temperature variations, and on critical aspects related to the analog-to-digital conversion and the signal demodulation.

Being the direct counterpart of C.F.
