Download or read book GPS User Equipment Performance Evaluation written by ITT DEFENSE COMMUNICATIONS DIV NUTLEY N J. and published by . This book was released on 1979 with total page 82 pages. Available in PDF, EPUB and Kindle. Book excerpt: The significance of this research and development project to the Air Force is that it provides for a hot-bench simulation facility to validate GPS (Global Positioning System) User Equipment performance under various flight dynamics and environments and provides a data base for comparison with flight test results. This would also enable systematic evaluation of the performance of the GPS User Equipment in a simulated hostile electromagnetic environment. This simulation includes the generation of: GPS RF signals, jammer RF signals, white Gaussian noise, GPS navigation data, on-board sensor signals (i.e. IMU and altimeter), path loss and antenna pattern. As part of the simulation, error models for various functions and phenomena including IMU, altimeter, ionospheric and tropospheric delay, gravity anomaly, ephemeris, and clock error are included. The simulator precisely couples the changes in RF signals to the physical dynamics of the system (i.e., user, satellite, and jammer motions), including lever arm effects. The GPSE is currently designed to simulate five GPS satellite RF signs and five jammer RF signals. The entire simulation is under computer control in real time, utilizing as the input pre-computed data defining the user flight profile, jammer, and satellite motion.

This book was released on 1999-01-01 with total page 68 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report describes a method where the Global Positioning System (GPS) Precise Positioning Service (PPS) solutions recorded in the field can be reprocessed at a later time with the precise ephemerides without requiring that the observations be saved. The reprocessing with the precise ephemerides improves the quality of the navigation solutions compared with the solutions obtained when the real-time broadcast ephemerides are used. This report continues the investigation of the Precise Absolute Navigation (PAN) technique by exploring its accuracy under highway conditions. Ellipsoid height solutions from survey vehicles traveling at highway speeds have the potential to map terrain heights in a fast, efficient manner. The absolute terrain heights, determined from GPS ellipsoid height solutions, can be used to calibrate remote sensing devices, such as Synthetic Aperture Radar (SAR) images. The performance of PAN is compared with PPS solutions, range-corrected Standard Position Service (SPS) solutions, and relative solutions using smoothed pseudorange. The relative merits of each are discussed.

Military and published by . This book was released on 2018-03-05 with total page 148 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is one of a series of systems engineering case studies prepared by the Air Force Center for Systems Engineering. This case study analyzes the Global Positioning System (GPS). It is a satellite-based radio navigation system. It provides suitably equipped users the capability to precisely determine three-dimensional position and velocity and time information on a global basis. The capability was developed to provide the United States and DoD with worldwide navigation, position, and timing capabilities to support military operations by enhancing ground, sea, and air warfighting efficiencies. However, by presidential directive, it was officially made available to the civilian community in 1983. GPS also provides the capability to conduct time transfer for synchronization purposes through the use of precise time standards. GPS supports a secondary mission to provide a highly survivable military capability to detect, locate, and report nuclear detonations in the Earth's atmosphere and in near-Earth space in real time. The study provides a wealth of technical information about this vital satellite-based system and its complex history. The Department of Defense is exponentially increasing the acquisition of joint complex systems that deliver needed capabilities demanded by our warfighter. Systems engineering is the technical and technical management process that focuses explicitly on delivering and sustaining robust, high-quality, affordable solutions. The Air Force leadership has collectively stated the need to mature a sound systems engineering process throughout the Air Force. Gaining an understanding of the past and distilling learning principles that are then shared with others through our formal education and practitioner support are critical to achieving continuous improvement.

Book excerpt: A Sandia project currently uses an outdated Magnavox 6400 Global Positioning System (GPS) receiver as the core of its navigation system. The goal of this study was to analyze the performance of the current GPS receiver compared to newer, less expensive models and to make recommendations on how to improve the performance of the overall navigation system. This paper discusses the test methodology used to experimentally analyze the performance of different GPS receivers, the test results, and recommendations on how an upgrade should proceed. Appendices contain detailed information regarding the raw data, test hardware, and test software.
