Available in PDF, EPUB and Kindle. Book excerpt: With the initiation of the navigation accuracy prediction algorithm used to estimate the amount of GPS solution (location and time) error for receivers, the capability to accurately predict solution errors due to the major GPS error sources is growing. Although some sources of error within the GPS solution have been previously analyzed, modeled, and/or accounted for within various modeling efforts, a formal evaluation of the seven major error sources that distort GPS activity has not been officially conducted up until this point. This research offers a logical assessment of all the major GPS error sources and their definitive impact on the end user. This research describes the major error sources in the GPS solution, which includes error sources from the spacecraft propagation of the signal through space, and receiver errors for a representative family of receivers. Once we define these error sources, we prioritize these sources with respect to benefit-to-cost ratios. We base the benefit-to-cost ratio on an error's accountability to the modeling effort required. This research recommends a prioritized order of future enhancements for error source implementation and improvements in future GPS accuracy prediction models, with a complete explanation of the tradeoffs associated with each improvement.

This book was released on 1983 with total page 167 pages. Available in PDF, EPUB and Kindle. Book excerpt: A Triservices study, currently in progress, will develop representative test and training range instrumentation configurations based on NAVSTAR Global Positioning System (GPS) technology, evaluate performance capabilities, and develop cost information. During the early phase of the study a collection of GPS documentation was established for reference purposes. This documentation along with experience from other GPS projects at WSMC provided the basis for the report. This report provides information that should be useful to range analysts developing and evaluating GPS-based instrumentation concepts at the test and training ranges. Some of the subjects are not thoroughly developed and may require further work. Subjects addressed include definition of performance evaluation terms, Doppler data processing, use of pseudo-satellite ground stations, two and three dimensional solutions, receiver and translator configurations, and vehicle dynamics effects on receiver operation.

Download or read book Detection of GPS C A Code Self Interference An Evaluation of Monitors written by Jessica A. Belzer and published by . This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Global Positioning System (GPS) self-interference is a pressing challenge in GPS safety-of-life applications. The need for mitigation of self-interference is increasing in importance with the growing number of global satellite navigation systems (GNSS) and satellites in orbit. Self-interference induced errors have previously been considered to originate from receiver-tracked satellite signals. The error can also originate from untracked or unhealthy ghost satellites and flex power events. Self-interference often occurs in short duration events that produce minimal error effects on a GPS receiver. However, worst-case scenario events can occur over several seconds. To use GPS for safety-of-life applications such as aircraft precision approaches, the navigation solution for a user must be robust to worst-case error sources of relatively low probability. In recent years, flex power capability has been added to the GPS constellation. Flex power events can change the transmit power of GPS L1 C/A satellite signals, increasing cross-correlation between signals that would otherwise produce a negligible error event. As a result, self-interference has become more difficult to predict. A safety-of-life application of interest in this research is the use of GPS in the Ground Based Augmentation System (GBAS) for commercial aircraft precision approaches. To maintain a high-accuracy, high-integrity solution, self-interference errors must be detected or mitigated, and separated from errors caused by other sources. This research identifies the requirements of a self-interference detection or mitigation solution for the GBAS Approach Service Type D (GAST D) environment. This dissertation investigates three existing GBAS monitors for their ability to detect self-interference on the pseudorange measurements. These include the Code Carrier Divergence (CCD) monitor, the DSIGMA, and the Bias-Value (B-Value) monitor. Evaluation of the monitors is also relevant to their potential for misidentification of error under their existing applications. A novel Frequency Domain Cross-Correlation (FDCC) detector is also proposed. Monitors are evaluated based on their response to a worst-case self-interference event. GBAS GAST D accuracy and integrity requirements are used as a metric to gauge the performance of the monitors. All monitors were found to respond to self-interference on the pseudorange measurement. The CCD monitor, DSIGMA, and B-Value monitor using smoothed measurements are not recommended to be applied to detect self-interference in the GBAS GAST D environment. The B-Value monitor using unsmoothed pseudorange measurements and the FDCC detector were demonstrated as feasible monitors for application in the GAST D environment for detection of the error based on the performance metrics. Results show the B-Value monitor requires a minimum of three receivers placed in a diverse geometry. The FDCC detector detects self-interference based on its characteristic frequency modulation, offering early, self-interference-specific detection without siting constraints.

This book was released on 2012-12-06 with total page 336 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is dedicated to Dr. Benjamin William Remondi for many reasons. The project of writing a Global Positioning System (GPS) book was con ceived in April 1988 at a GPS meeting in Darmstadt. Dr. Remondi discussed with me the need for an additional GPS textbook and suggested a possible joint effort. In 1989, I was willing to commit myself to such a project. Un fortunately, the timing was less than ideal for Dr. Remondi. Therefore, I decided to start the project with other coauthors. Dr. Remondi agreed and indicated his willingness to be a reviewer. I selected Dr. Herbert Lichtenegger, my colleague from the University of Technology at Graz, Austria, and Dr. James Collins from the United States. In my opinion, the knowledge of the three authors should cover the wide spectrum of GPS. Dr. Lichtenegger is a geodesist with broad experience in both theory and practice. He has specialized his research to geodetic astron omy including orbital theory and geodynamical phenomena. Since 1986, Dr. Lichtenegger's main interest is dedicated to GPS. Dr. Collins retired from the U.S. National Geodetic Survey in 1980, where he was the Deputy Director. For the past ten years, he has been deeply involved in using GPS technology with an emphasis on surveying. Dr. Collins was the founder and president of Geo/Hydro Inc. My own background is theoretically oriented. My first chief, Prof. Dr. Peter Meissl, was an excellent theoretician; and my former chief, Prof. DDDr. Helmut Moritz, fortunately, still is.
