This paper investigates the capability of the existing GPS constellation to meet FAA RAIM (receiver autonomous integrity monitoring) requirements for en route civilian flights over the continental United States (CONUS). The analysis shows that the current GPS constellation does not meet the FAA en route requirements when the effect of expected satellite failures requiring replacements are considered. An enlarged constellation, with either 5 additional satellites in a 0/spl deg/-inclination plane or 6 additional satellites distributed in the 55/spl deg/-inclination planes, will achieve the (1-10/sup -5/) RAIM availability requirement. The sensitivity of RAIM availability to various system parameters was also studied. These include: receiver masking elevation angle, horizontal navigation error limit, aiding baro-altimeter measurement error, and probability of missed detection. Reducing the allowable elevation angle to 0/spl deg/, which may be permissible for en route flights, significantly improves availability provided by the current 24 satellite constellation from 0.9976 to 0.9905.","PeriodicalId":125963,"journal":{"name":"Proceedings of 14th Digital Avionics Systems Conference","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1995-11-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134209545","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 NCOSEKAWG Interim Model has been under development for the past year and a half, with its initial release in April 1994. The NCOSEICAWG Interim Model is a preliminary attempt to assess systems engineering capability with respect to a subset of the requirements defined by the CAWG for this purpose. The NCOSE/CAWG Interim Model can be viewed as filling a void, since the CAWG believes that a complete Capability Assessment Model for Systems Engineering that satisfies all requirements defined by the CAWG for such a model currently does not exist. The paper also presents a synopsis of the background leading up to the development of the NCOSEKAWG Interim Model and a description of the planned activities focused on both improving and offering a degree of validation to the NCOSEKA WG Interim Model and its supporting documents. A key feature of the improvementhalidation activity is a series of CAWG facilitated Systems Engineering Process Assessments (SEPAs) at selected companies.","PeriodicalId":125963,"journal":{"name":"Proceedings of 14th Digital Avionics Systems Conference","volume":"81 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1995-11-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129003659","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}

It was envisioned that a number of enhancements of the modern cockpit would use the mode-S data link. At the time of the development of the mode-S transponder, it was also envisioned that the mode-S transponder would receive a high level of penetration into the secondary radar transponder population because of mandated installation of modes. The mode-S data link is often suggested as an appropriate data link but there are some concerns about the data capacity of the mode-S system. The mode-S system already shares the 1030/1090 MHz frequency pair with ATCRBS transponders and TCAS. Since there is only one frequency pair, every user, world-wide, shares these frequencies. The mode-S system is first, and foremost, a part of the air traffic control radar system and the data link is a secondary operation. Under no circumstances should the data link portion of the mode-S system jeopardize the primary function of the transponder. It was determined that a surveillance system would be an important tool to analyze the amount and type of activity on the 1030/1090 MHz frequency pair. This tool, essentially a recording receiver, would be useful in assessing the potential problems of adding additional loading on the 1030/1090 MHz frequency pair. The receiver design is described and the results of activity tests are presented and compared to previous tests.","PeriodicalId":125963,"journal":{"name":"Proceedings of 14th Digital Avionics Systems Conference","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1995-11-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127503187","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}
