In view of the existing location algorithm is always in 2-dimension form, Chan algorithm has been concluded in 3-dimension form and a 3-dimension location method based on TOA is proposed. The method transforms the nonlinear location equation into linear form by using initialization estimation coming from two-step weighed least square, then calculates the location estimation. The method is simple and precise. The simulation about it is given to show its theoretic value.","PeriodicalId":326534,"journal":{"name":"2008 ISECS International Colloquium on Computing, Communication, Control, and Management","volume":"261 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-08-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122689803","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}

And then the switching hyper plane is designed by applying the optimal control theory. During the change of parameter is little, 4WS steering performance is carried out by adopting sliding variable structure controller. To improve the steering performance of 4WS, especially state variables convergent velocity, Kalman filter for 4WS is designed. And the robust optimal controller is designed for model and parameter is uncertainty.

We investigate how to evaluate the quality of onboard dual frequency kinematic GPS receiver using in-flight observations, and provide several indices of onboard observation quality evaluation. To come over high dynamic characteristics of onboard observations, we design an efficient method of outlier elimination and cycle slip detection. Then via linear combination of original observations, the kinematic observations noise is extracted, and the observation quality is evaluated. Further more, we provide an algorithm to compute the correlation of different types of observations, and analyze the relation between the observation quality and sightline direction. We achieve a series of reliable quality evaluation results by experiments on the data from CHAMP satellite and provide reasonable explanation. The results of CHAMP data analysis contribute to better understanding of receivers and applications of GPS.","PeriodicalId":326534,"journal":{"name":"2008 ISECS International Colloquium on Computing, Communication, Control, and Management","volume":"89 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-08-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133380111","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}

In the paper, we propose an energy-aware multicast routing algorithm for WSNs. The algorithm is based on geographic routing, and defines the multicast region as rectangle that has smallest area but covers all destination nodes, where an access point is selected as a gateway. The whole routing process includes two phases. The first phase is to seek a minimal energy path from the sink to the access point based on the idea of dynamic programming. The second phase is to search for a broadcast tree between the access point and the destination nodes in the multicast region. Experiments indicate that our algorithm has better performance on energy expends and success rate of tree setup.","PeriodicalId":326534,"journal":{"name":"2008 ISECS International Colloquium on Computing, Communication, Control, and Management","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-08-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134568877","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}
