Abstract:	The GPS Toolkit, or GPSTk, is an open source project that provides a software suite to the GNSS community. The goal of the project is to free researchers to focus on research, not lower-level coding. The suite is composed of a library and a suite of applications built on the library. Since the GPSTk was last presented at the ION GNSS 2006, the project has grown in scope and user base. Metrics provided by service providers SourceForge and Google quantify that growth. To accommodate the increase in demand and code complexity, the documentation system has been replaced with a community-managed website or wiki. The project has customized the wiki to support documentation commonly associated with GNSS software development. Because the project is open source, new contributions are key to its success. The library has been reorganized to preserve contributions that are experimental or application specific. The new organization preserves usability and stability of the library’s core functionality. The core library has been modified as well. Data structure and almanac processing classes have been added. New applications have also been contributed. This includes two suites of applications, one that simulates tracking the GPS signal and another that analyzes range residuals.
