The real-time precise products: orbit corrections, clock corrections and code biases are provided by the real-time service (RTS) of the International GNSS Service (IGS). The international GNSS service provides the access to real-time orbit corrections but RTS availability is sometimes disturbed or communication link is interrupted. Unfortunately any correction outage, either due to corrupted ephemeris or loss of communication link, will degrade the precise satellite position. Because it happens that corrections are not available in 100 % or they are sent with a certain latency it is necessary to apply the solution that will extend the application period of corrections until the connection will recover. For this purpose one can extrapolate directly the geocentric corrections. The prediction of corrections can be performed using the polynomial function. In this article, the authors analyze polynomial function using a different polynomial degree when predicting sought quantities. The tests were performed using various degree of polynomial calculation. To analyze this problem the own software was used. The software gets streams with SSR correction from IGS service. The experiment was performed in a several scenarios with several streams for different GPS satellites. The prediction time, accuracy and the degree of polynomial were tested for the best result. The results obtained in various scenarios were compared in order to find the optimal method geocentric corrections prediction. The time and accuracy of the prediction were chosen as the main comparative criteria.","PeriodicalId":243907,"journal":{"name":"2018 25th Saint Petersburg International Conference on Integrated Navigation Systems (ICINS)","volume":"51 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115998202","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}

On the basis of considering pedestrian dynamic model, using MEMS inertial sensors, the structure of pedestrian navigation devices, pedestrian autonomous navigation algorithm and corresponding experimental are designed and researched. In the process of structure design, considering the convenience of pedestrian wear and the abundant information of signal acquisition, the device can be worn in different locations of the human body. The algorithm in this paper can extract the human movement characteristics under different wear mode adaptively, and calculate the pedestrian movement parameters. And then the short-term and high-precision pedestrian autonomous positioning can be realized. In addition, the device developed in this paper was used to perform pedestrian walking experiments. The results show that the developed prototype device wears flexibly, and can satisfy the need of short-term, autonomous and high accuracy localization for pedestrian. This article and its result are available and referable for the institutes researching autonomous positioning technology in indoors, jungle, underground, tunnels and other navigation non-cooperative environments.","PeriodicalId":243907,"journal":{"name":"2018 25th Saint Petersburg International Conference on Integrated Navigation Systems (ICINS)","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125049057","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}

We deduce a mathematical model which describes nonlinear oscillations of the resonator when the control voltage is applied to the electrodes. Various schemes and modes of supplying voltage to the gyroscope sensors are studied. It is shown that reference voltage causes cubic nonlinearity, and alternating voltage causes quadratic nonlinearity of control forces in one mode of the supplying voltage. In another mode, apart from the cubic nonlinearity caused by the reference voltage, there are both the constant component and quadratic nonlinearity. To linearize the resonator oscillations, special supplying voltage modes for the control electrodes are presented. The formed control modes compensate for the nonlinear resonator oscillations caused by the electrostatic sensors. The proposed technique can be used to eliminate nonlinear oscillations and to linearize force characteristics of control sensors for wave solid-state gyroscopes with ring resonators.","PeriodicalId":243907,"journal":{"name":"2018 25th Saint Petersburg International Conference on Integrated Navigation Systems (ICINS)","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131711615","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}
