The author describes a flight test performed in Japan using a GPS (Global Positioning System) navigation system. A low-cost C/A code GPS navigation system (Pioneer AVIC-1) which consists of a three-channel sequential receiver and map display was installed on an experimental aircraft together with VOR/DME airborne experiment and a baro-altimeter. The data collected are position, velocity vector, and DOP derived from GPS and bearing, distance, altitude from VOR/DME/ALT during the entire flight. Fixed-point continuous observation on GPS data was also performed for 24 hours. The flight test results obtained show very high accuracy and smooth track trajectory compared with VOR/DME position data during approach and departure. The continuous observation results indicate that the two-dimensional position fix error and height error of GPS are 25 to 30 m (2* rms) and 70 to 90 m (2* rms), respectively.<<ETX>>","PeriodicalId":422101,"journal":{"name":"IEEE PLANS 92 Position Location and Navigation Symposium Record","volume":"27 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":"129381423","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 resulting single data stream is that of carrier phase measurements with both data noise and bias uncertainty strictly defined. With this analytical formula the single stream of equivalent GPS measurements can be efficiently formed by simple numerical calculations without any degradation in data strength. The formulation for the optimally combined GPS data and their covariances are given in closed form. Carrier phase ambiguity resolution, when feasible, is improved due to the preservation of the full data strength with the optimal data combining process.<<ETX>>","PeriodicalId":422101,"journal":{"name":"IEEE PLANS 92 Position Location and Navigation Symposium Record","volume":"23 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":"128134388","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}

Currently, an estimate of the state is computed using the method of least squares on data consisting of network structural data and a sufficient set of bus voltage magnitude and power flow measurements. It is shown that, using GPS (Global Positioning System) time to synchronize measurements, the measurement data set can be augmented with accurate voltage phase measurements. By incorporating accurate phase measurements from buses at major substations in the power network, more accurate state estimates can be computed. More importantly, however, bad measurements can be isolated more easily and removed from the estimation process altogether, yielding an even more accurate state-estimate. Accuracies of 1 mu s are easily achieved for synchronization via GPS time, giving relative phase measurement accuracies of sigma =282 mu rad. A GPS receiver and synchronization system would be very small and potentially inexpensive, as the prices of GPS receivers are decreasing rapidly.<<ETX>>","PeriodicalId":422101,"journal":{"name":"IEEE PLANS 92 Position Location and Navigation Symposium Record","volume":"84 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":"127732294","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 discusses the methodology of AT&T's approach to synchronization of its telecommunication network using Global Positioning Satellite (GPS) receivers in its Primary Reference Clock (PRC) systems. Each PRC utilizes a triad of GPS and rubidium references along with special analysis software. The result is an ultrastable, verifiable, digital timing signal which is typically one hundred times better than the CCITT G.811 requirements. This system provides timing signals without having a track satellites continuously. Statistical processing of data using a triple point array of GPS and dual disciplineable rubidiums ensures stable output signals. The AT&T synchronization network thus operates plesiochronously, considering the multiple PRC sites located throughout the continental United States. However, these PRCs are all operating synchronously via the GPS satellite system.<<ETX>>","PeriodicalId":422101,"journal":{"name":"IEEE PLANS 92 Position Location and Navigation Symposium Record","volume":"2371 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":"130430997","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 usual techniques of satellite attitude determination, such as utilizing inertial guidance components, are fairly expensive, especially if high accuracies are required for the mission. The authors explore a lower-cost alternative yielding equal or better accuracies, reliability, and repeatability. The approach under consideration utilizes the Global Positioning System (GPS) with either multiple antennas for one or more receivers spaced appropriately on the outer surface of the spacecraft. Consideration has also been given to supplementing GPS with the Global Navigation Satellite System (GLONASS) in order to increase the number of satellites visible at all times. The effects of this combination are discussed not only in terms of coverage but also to whether accuracy is enhanced or degraded due to the inherent characteristics of GLONASS. It has been demonstrated by simulation that satellite attitude determination using GPS is feasible, practical, and cost-effective for a variety of missions.<<ETX>>","PeriodicalId":422101,"journal":{"name":"IEEE PLANS 92 Position Location and Navigation Symposium Record","volume":"3 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":"127452772","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}
