The authors present an application of attitude velocity match algorithms useful for attitude keeping of an interceptor navigation and target acquisition system. It operates by comparing computed attitude and velocity from a high-quality launch vehicle inertial measurement unit (IMU) with the attitude and velocity computed using a strapdown payload IMU. The residual attitude and velocity differences measured during launcher boost, divert manuevers to shape the launcher trajectory, and/or freefall are a direct indication of mechanical misalignments, interceptor initial attitude error, and IMU uncertainties, and are used in a Kalman filter to estimate those quantities. A detailed analysis of a transfer alignment and instrument calibration filter for a payload IMU has been carried out. Also obtained was a complete derivation of the attitude/velocity match algorithms. A filter sizing study was carried out, and the sensitivity of the suboptimal filter to the unmodeled error states and the incorrectly modeled measurement noise and errors are evaluated.<<ETX>>","PeriodicalId":422101,"journal":{"name":"IEEE PLANS 92 Position Location and Navigation Symposium Record","volume":"257 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1992-03-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116420027","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}

Thus, what is required in this case is not statically, but dynamically, high accuracy. However, few systems are available to get a fixed position at high accuracy for dynamic maneuvering, and the analysis of the dynamic data requires a position-by-position comparison. A dead reckoning system with excellent accuracy has been used for the comparison to GPS position. The value of the results derived using this approach depends heavily on careful synchronization of time during the tests carried out. The results obtained through the latest dynamic tests and applications for future navigation are discussed.<<ETX>>","PeriodicalId":422101,"journal":{"name":"IEEE PLANS 92 Position Location and Navigation Symposium Record","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1992-03-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127725603","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 material is developed from the analysis of error contour plots, which provide the guidance system errors along the desired approach path due to signal scattering from a surface vehicle. The contour data are generated by executing the microwave landing system (MLS) mathematical model considering an interfering surface vehicle positioned at selected locations on an M*N grid and analyzing the model data as described. Optimal grid spacing is necessary to accurately describe the errors as a function of surface vehicle location while minimizing the simulation time required. A method based on the two-dimensional fast Fourier transform is described to estimate the spatial frequency spectrum of the contour data. Once spectral estimates become available, the optimal grid spacing is obtained using the Nyquist sampling theorem. To further reduce the overall processing time of this task, parallel processing is desired. A technique for parallel implementation on a Symult S-2010 message passing system is presented.<<ETX>>","PeriodicalId":422101,"journal":{"name":"IEEE PLANS 92 Position Location and Navigation Symposium Record","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1992-03-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127617600","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}

Towards this goal, advanced automated en route ATC (AERA) concepts are currently in the research and development phase to provide a gradual evolution of ATC automation capabilities. The airborne flight management systems (FMSs) can provide accurate information on aircraft states needed to meet the automation objectives of advanced AERA concepts. The impact of user-preferred flight paths and altitudes on future ATC operations is analyzed. The results highlight potential fuel savings for the airspace users. Air/ground functional integration and information flow are discussed to minimize data ambiguities, and to reduce duplication of data in the airborne and ground computers. Computer/human interface requirements are also addressed. Key technical issues which must be addressed in order for the ground system to support flexible use of airspace, and increase system capacity in a diverse mix of aircraft operations are identified. The results presented show that FMS-equipped aircraft could realize significant fuel savings if permitted to fly preferred altitudes using step climbs.<<ETX>>","PeriodicalId":422101,"journal":{"name":"IEEE PLANS 92 Position Location and Navigation Symposium Record","volume":"226 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1992-03-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124494901","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 same stations can also be used for the implementation of a differential mode of operation, through the transmission of measurement corrections relevant to the tracked GPS (Global Positioning System) satellites. A combined operation of the stations is implemented in this manner. For civil aviation applications, the system operation can be enhanced with the integration of four multistationary satellites within the GPS space segment. The addition of four multistationary satellites will extend the integrity monitoring and system availability worldwide up to very high latitudes. The adoption of multistationary satellites presents valuable advantages over geostationary satellites.

The data given are from Sundstrand Data Control's RBA-500 accelerometer. The design goal in the RBA-500 has been to achieve minimum cost, size, and weight while relying on good symmetry and crystal matching to provide the common mode error rejection necessary to reach acceptable tactical grade performance. Two force crystals are necessary to reduce errors to reasonable levels. It is noted that various models are available with different accuracies and computational demands, but the microprocessors coming on line should have no trouble handling the task at high sample rates. The chosen model can be massaged to reduce selected errors.<<ETX>>","PeriodicalId":422101,"journal":{"name":"IEEE PLANS 92 Position Location and Navigation Symposium Record","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1992-03-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133783794","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}
