Download or read book Subsampling GPS Receiver Front end written by Carsten Barth and published by Stanford University. This book was released on 2011 with total page 122 pages. Available in PDF, EPUB and Kindle. Book excerpt: Research in RFIC design has recently shifted towards direct conversion and subsampling architectures as an alternative to the conventional super-heterodyne architectures. Bandpass sampling architectures, also called subsampling architectures, exhibit several advantages over super-heterodyne architectures, notably, the complexity of subsampling architectures is significantly lower since no phase-locked loop is required. A direct consequence is that downconversion from RF to IF can be achieved with significant power savings as compared to the super-heterodyne architecture. Another significant benefit of such architectures is the capability for processing multiple signals in parallel. The ability to simultaneously handle multiple carriers makes subsampling architectures particularly well suited for GNSS applications, as downconversion of multiple frequency bands is required in GNSS environments. With the advent of the new civilian GPS signals, L2C and L5, and the onset of the new Galileo signal, a receiver that can process multiple signals without adding complexity, is highly desired. An integrated proof-of-concept subsampling GPS receiver front-end in 130 nm BiCMOS is presented in this dissertation. The receiver achieves a noise figure of less than 3.8 dB, the lowest ever recorded noise figure of a subsampling based receiver.
Download or read book Fundamentals of GPS Receivers written by Dan Doberstein and published by Springer Science & Business Media. This book was released on 2011-10-22 with total page 331 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fundamentals of GPS receivers covers GPS receivers' theory and practice. The book begins with the basics of GPS receivers and moves onward to more advanced material. The book examines three types of GPS receiver implementations: first is the custom design by the author; second is an industry standard design, now part of the open source network; the third relates to the receiver designed by JPL /NASA. Each receiver is unique allowing the reader to see how each design solves the same problems. Chapters discuss carrier phase measurements and GPS time and frequency measurements. The overall text is measurement oriented as opposed to processing the measurements. With a focus on the fundamentals of measurements the reader will be building their intuition for the physical phenomenon at work.

This book was released on 2018-07-23 with total page 118 pages. Available in PDF, EPUB and Kindle. Book excerpt: Master's Thesis from the year 2017 in the subject Geography / Earth Science - Geology, Mineralogy, Soil Science, grade: 1.0, Technical University of Darmstadt (Fachbereich Geo- und Material-Wissenschaften), course: Abschlussarbeit im MSc TropHEE (tropical Hydro-Geology and Environmental Engineering) in Zusammenarbeit zwischen Geologie und Geodäsie (Bau-Ingenieurwesen), language: English, abstract: An introduction into the theory of software defined receivers and especially in such for detecting GNSS signals, acquiring and tracking GNSS satellites, calculating pseudo ranges, positions, velocity and time (PVT) is presented. Basis of the practical work was the open source project SoftGPS, programmed in Matlab and published by (Borre 2007). The Radio Frequency front end (RF-FE) used in this project was no longer available and was replaced by one with different behavior: NSL Stereo (amplifier, mixer, sampler, and A/D converter in two chains). Adaptations, corrections and extensions to the Matlab code were neces-sary to work with the new front end and to get new functions. With Stereo came also new Matlab- and C/C++ code that did not work properly. Parallel to the projected working environment – Ubuntu 16.04 Linux with Matlab 2016a – also Windows 10-64bit and a Windows XP-64bit beta-software from NSL from January 2013 had to be used due to long delays at NSL to provide updated / working Linux versions: the original software from 2012 for Ubuntu 10 was not working in any newer Linux distribution. Finally a version for Ubuntu 14.04-64bit from Jan 2016 was provided after most of the grabbing of different GNSS-signals was already done. Code of (Borre 2007) and of NSL for Stereo RF-FE were thoroughly analyzed and documented. Besides own descriptions also the M2HTML documentation generator and GraphViz (for generating dependency graphs) were used. The software was also changed and expanded to archive demands for more modularity, performance, quality and functionality (C/No calculation, output of correct velocities in UTM coordinates, statistics about positions and velocities, continuous processing, ...). As code release tool, Git was used for a complete change history and to be able to recover old versions of the code. With the Git-Bash, identical (UNIX-like) behavior was achieved on both Linux and Windows platforms. Git is more modern than the system used in (Borre 2007) and integrated in Matlab. Even with only 4 parallel processes (in a notebook) and a processing conditioned by signal to noise ratios C/No the most time consuming tracking was reduced to about a quarter of the initial processing time.
Download or read book A Low Power RF Front End Architecture for an L1 L2CS GPS Receiver written by and published by . This book was released on with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: With the apparition of several new civilian signals in the years to come, there will soon be great demand for multifrequency receivers. As soon as two signals will be available, users will be able to correct the ionospheric error, the main source of error since the SA has been disabled. Multifrequency receivers will also be able to switch between the current L1 C/A code and the new modernized signals to make best use of their individual characteristics. As expected, the improvements in performance will be accompanied by an increase in complexity, more noticeably at the RF front-end. In this paper, we discuss the different solutions to realize an RF front-end for a dual-frequency GPS receiver and propose an innovative solution which has a power consumption comparable with that of a single-frequency front-end.
Download or read book A GPS written by Frank Stephen Tromp Van Diggelen and published by Artech House. This book was released on 2009 with total page 400 pages. Available in PDF, EPUB and Kindle. Book excerpt: Today, increasing demands and expectations are being placed on GPS systems. Assisted GPS (A-GPS) has been developed to provide greatly improved capabilities, helping GPS work better and faster in almost any location. Offering a detailed look at all the technical aspects and underpinnings of A-GPS, this unique book places emphasis on practical implementation. The book reviews standard GPS design, helping you understand why GPS requires assistance in the first place. You discover how A-GPS enables the computing of a position from navigation satellites in the absence of precise time - a topic not covered in any other book. Moreover, you learn how to design and analyze a high sensitivity GPS receiver and determine the achievable sensitivity of a GPS receiver. The book provides detailed worksheets that show how to compute, analyze, and improve the processing gain from the signal strength at the antenna to the carrier-to-noise ratio (C/N0) at the front end, to the signal-to-noise ratio (SNR) after the correlators. This cutting-edge volume discusses special forms of assistance data, industry standards for A-GPS, and government mandates for location of mobile phones. You also find coverage of future global navigation satellite systems and how they can be designed specifically for instant-fixes and high sensitivity. The book features numerous tables, worksheets, and graphs that illustrate key topics and provide the equivalent of a technical handbook for engineers who design or use A-GPS.
