Litton Aero Products has recently completed flight testing a prototype of their latest INS/GPS (Global Positioning System/inertial navigation system) system mechanization in which the LTN 2001 GPS PR and DR measurements are sent directly to the LTN-92 INS Kalman filter by means of an ARINC 429 interface. The advantage of this approach is that individual satellite measurements are used independently in the INS Kalman filter. These measurements are therefore uncorrelated, and can be correctly modeled in a single, integrated INS/GPS Kalman filter which optimally combines information from both systems. Yet, the GPS sensor is an independent unit which is not embedded in the INS. For civil aviation, this PRDR mechanization makes possible a delayed, integrity-assured integration algorithm. This mechanization was flight-tested in Litton's Cessna Citation aircraft and also in Boeing's Advanced Avionics Test Bed aircraft.<<ETX>>","PeriodicalId":422101,"journal":{"name":"IEEE PLANS 92 Position Location and Navigation Symposium Record","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127738309","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}

Recent inertial measurement unit (IMU) development experience has shown that common components and design philosophies can meet the requirements of diverse missions. IMUs and attitude reference units (ARUs) built for hypervelocity projectiles, tactical missiles, precision munitions, and space interceptors have used these common approaches successfully. Each mission has major unique driving requirements: hypervelocity vehicles demand small diameters and have very tight form factor requirements, tactical missiles demand low cost, precision munitions require g-hardness for gun launches, and space interceptors demand low weight. A ring-laser-gyroscope-based cluster dither system approach, appropriately tailored to each application, provides integrated, self-contained, and testable IMUs and ARUs which meet the requirements for all these missions. The authors have examined the system architecture for building IMUs for each of these applications while stressing the common features which achieve the critical needs of each mission.<<ETX>>","PeriodicalId":422101,"journal":{"name":"IEEE PLANS 92 Position Location and Navigation Symposium Record","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126945471","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 FAA's Satellite Program Office is developing a satellite approach testbed at the FAA's Technical Center (FAATC) in order to determine the feasibility of precision approaches using only GPS (Global Positioning System) augmented with wide-area differential GPS corrections. The differential corrections will be broadcast from a single geostationary satellite and will be applicable for precision approaches by all users in the contiguous USA. The authors will describe the wide-area differential GPS concept, and report on the development and test results from the application of wide area differential GPS for precision approaches at the FAATC Satellite Approach Test Bed. The technical issues addressed are possible accuracies with wide-area differential GPS, accuracies versus number of required monitor locations, and techniques for real-time ionospheric and tropospheric corrections.<<ETX>>","PeriodicalId":422101,"journal":{"name":"IEEE PLANS 92 Position Location and Navigation Symposium Record","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124576339","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}
