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 that use that library. The library provides common routines such as those developed in satellite navigation texts. The applications support greater depth of functionality to support research and development. The applications are almost entirely console based (i.e., without a graphical user interface). They can be grouped functionally into a number of categories: basic transformations of time and coordinate systems, observation data collection and conversion, file comparison and validation, data editing, ionosphere modeling, and autonomous and relative positioning. New applications have been added to the suite over the last year. One new application, DDBase, can be used to generate baseline solutions with millimeter level accuracy. The library has been enhanced in the last year and low level input and output capability for BINEX data has been added. Future contributions to the library include support for the Receiver Independent Exchange Format (RINEX) Version 3 format.
