The NavCore V commercial GPS (Global Positioning System) receiver engine is a high-performance receiver designed to provide the system integrator with the core GPS capability to support a variety of products. NavCore V system tests have been conducted with Rockwell satellite simulators and with live GPS satellites. The response of the system has been characterized over a variety of test stimuli and operating conditions. The results confirm the advantages of incorporating high-performance GPS receiver technology into the commercial environment. Significant performance advantages are demonstrated as compared to sequential GPS receivers, which often have slow signal acquisition and sluggish performance during dynamic maneuvers.<<ETX>>","PeriodicalId":422101,"journal":{"name":"IEEE PLANS 92 Position Location and Navigation Symposium Record","volume":"32 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":"133312287","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 Strategic Defense Initiative Organization (SDIO) has sponsored Adroit Systems' development and testing of an attitude determining system (ADS) based on GPS (Global Positioning System) satellite signal interferometry. The relative phase difference of the GPS carrier is measured between a pair of antennas spaced 1 m apart to determine the antenna baseline pointing vector. The system requires only three satellites to operate once the position of the antenna is ascertained. Double differencing is used to eliminate RF bias and drift between antennas. The second generation of this ADS was delivered in 1990 to the USA Army Engineer Topographic Laboratory for evaluation. This Adroit ADS can calculate and update pointing information each second. Accuracy was demonstrated in Army tests to approximately 10 milliradians in one second, and below 1 milliradian with a 300 second sample time.<<ETX>>","PeriodicalId":422101,"journal":{"name":"IEEE PLANS 92 Position Location and Navigation Symposium Record","volume":"100 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":"122828380","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 general topography of this mountainous area is described, together with the specific topographic features and tree coverage characteristics of the 2000 km of roads tested on the mainland and on Vancouver Island. The configuration and characteristics of the Loran-C Canadian West Coast chain along the roads used are described. The portable vehicle-mounted LORCAL (Loran Calibration at the University of Calgary) system used to collect and analyze the Loran-C and GPS signals along road profiles is described. The performance of Loran-C is analyzed in terms of signal to noise ratios, field strength, and time difference distortions, as measured by differential GPS. These distortions, which can reach several hundred meters over distances of less than 20 km, are analyzed in terms of topographic features. The possibility of using these time-independent distortions to calibrate Loran-C for use along the above roads is discussed. Masking of GPS signals due to topographic features and tree coverage along the roads is analyzed. A comparative analysis of Loran-C and GPS is presented in terms of signal availability and accuracy.<<ETX>>","PeriodicalId":422101,"journal":{"name":"IEEE PLANS 92 Position Location and Navigation Symposium Record","volume":"24 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":"117111115","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 author describes the aided inertial system developed for an air-launched supersonic low-altitude target (SLAT) missile. Designed for the US Navy to test ship defense systems, the vehicle was required (worst case) to fly accurately for long ranges without any position updates after launch. The crux of the problem was to design a prelaunch alignment filter that would minimize the inertial attitude errors at launch and thus the end-of-flight position errors due to boost acceleration. A filter sizing and tuning study was performed, and predicted accuracy was studied based on covariance analysis. These results have been compared with navigation performance measured during actual flight tests. The effects of different range-based tracking systems on overall navigation accuracy have also been investigated.<<ETX>>","PeriodicalId":422101,"journal":{"name":"IEEE PLANS 92 Position Location and Navigation Symposium Record","volume":"8 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":"127331501","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}

According to this approach, if one wants to determine whether some SV has a bias and, if so, how much, it should be included as a state to be estimated; under reasonably general conditions, a single SV bias is observable. In a 5-SV snapshot example, both conventional and extended RAIM form five different solutions, with each SV taking its turn in succession as the suspected bias source. Whereas conventional RAIM excludes the suspect SV from the solution, extended RAIM retains it while including the bias as a fifth unknown to be determined.<<ETX>>","PeriodicalId":422101,"journal":{"name":"IEEE PLANS 92 Position Location and Navigation Symposium Record","volume":"20 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":"134240781","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}
