An updated guide to GNSS and INS, and solutions to real-world GPS/INS problems with Kalman filtering Written by recognized authorities in the field, this second edition of a landmark work provides engineers, computer scientists, and others with a working familiarity with the theory and contemporary applications of Global Navigation Satellite Systems (GNSS), Inertial Navigational Systems (INS), and Kalman filters. Throughout, the focus is on solving real-world problems, with an emphasis on the effective use of state-of-the-art integration techniques for those systems, especially the application of Kalman filtering. To that end, the authors explore the various subtleties, common failures, and inherent limitations of the theory as it applies to real-world situations, and provide numerous detailed application examples and practice problems, including GNSS-aided INS, modeling of gyros and accelerometers, and SBAS and GBAS. Drawing upon their many years of experience with GNSS, INS, and the Kalman filter, the authors present numerous design and implementation techniques not found in other professional references. This Second Edition has been updated to include: GNSS signal integrity with SBAS Mitigation of multipath, including results Ionospheric delay estimation with Kalman filters New MATLAB programs for satellite position determination using almanac and ephemeris data and ionospheric delay calculations from single and dual frequency data New algorithms for GEO with L1 /L5 frequencies and clock steering Implementation of mechanization equations in numerically stable algorithms To enhance comprehension of the subjects covered, the authors have included software in MATLAB, demonstrating the working of the GNSS, INS, and filter algorithms. In addition to showing the Kalman filter in action, the software also demonstrates various practical aspects of finite word length arithmetic and the need for alternative algorithms to preserve result accuracy.

Until recently, building interactive web-based mapping applications has been a cumbersome affair. This changed when Google released its powerful Maps API. Beginning Google Maps Applications with PHP and Ajax was written to help you take advantage of this technology in your own endeavorswhether you're an enthusiast playing for fun or a professional building for profit. This book covers version 2 of the API, including Google's new Geocoding service. Authors Jeffrey Sambells, Cameron Turner, and Michael Purvis get rolling with examples that require hardly any code at all, but you'll quickly become acquainted with many facets of the Maps API. They demonstrate powerful methods for simultaneously plotting large data sets, creating your own map overlays, and harvesting and geocoding sets of addresses. You'll see how to set up alternative tile sets and where to access imagery to use for them. The authors even show you how to build your own geocoder from scratch, for those high-volume batch jobs. As well as providing hands-on examples of real mapping projects, this book supplies a complete reference for the Maps API, along with the relevant aspects of JavaScript, CSS, PHP, and SQL.

With the help of the Internet and accompanying tools, creating and publishing online maps has become easier and rich with options. A city guide web site can use maps to show the location of restaurants, museums, and art venues. A business can post a map for reaching its offices. The state government can present a map showing average income by area.Developers who want to publish maps on the web often discover that commercial tools cost too much and hunting down the free tools scattered across Internet can use up too much of your time and resources. Web Mapping Illustrated shows you how to create maps, even interactive maps, with free tools, including MapServer, OpenEV, GDAL/OGR, and PostGIS. It also explains how to find, collect, understand, use, and share mapping data, both over the traditional Web and using OGC-standard services like WFS and WMS.Mapping is a growing field that goes beyond collecting and analyzing GIS data. Web Mapping Illustrated shows how to combine free geographic data, GPS, and data management tools into one resource for your mapping information needs so you don't have to lose your way while searching for it.Remember the fun you had exploring the world with maps? Experience the fun again with Web Mapping Illustrated. This book will take you on a direct route to creating valuable maps.
