AB: Applied Research Laboratories, The University of Texas at Austin (ARL:UT) has established an open source software project called the GPS Toolkit, or GPSTk. In this poster we present an overview of the GPSTk focusing on structure, functionality, licensing, and applications of interest to the geodetic community. The GPSTk distribution is currently available for download on SourceForge. The GPSTk software distribution consists of source code for a core library, a test suite and a collection of applications. The GPSTk code has an object-oriented design and is written in ANSI C++. We intend the GPSTk to be platform independent; and it has been installed and tested successfully under Linux, Solaris and Windows. The code is released under the terms of the Lesser GNU Public License (LGPL). The functionality supported by the GPSTk, includes reading and writing observations to standard formats including RINEX, algorithms defined in the GPS signal-in-space interface control document (ICD-GPS-200), navigation solutions such as receiver-autonomous integrity monitoring (RAIM), atmospheric delay models, and P-code generation. We will provide a variety of examples of applications developed from the GPSTk, including a QA tool for GPS data, and generation of ionospheric total electron (TEC) values and vertical TEC maps from dual frequency GPS measurements. We will also discuss extensions under development, including applications to relative positioning, and will outline intended future development directions.
