What is GPSTk? -------------- The goal of the GPSTk project is to provide an open source library and suite of applications to the satellite navigation community--to free researchers to focus on research, not lower level coding. GNSS users employ practically every computational architecture and operating system. Therefore the design of the GPSTk suite is as platform-independent as possible. Platform independence is achieved through use of the ANSI-standard C++ programming language. The principles of object-oriented programming are used throughout the GPSTk code base in order to ensure that the code is modular, extensible, and maintainable. The GPSTk suite consists of a core library, auxiliary libraries, and a set of applications. The GPSTk provides a wide array of functions that solve processing problems associated with GNSS such as processing or using standard formats such as RINEX. The libraries are the basis for the more advanced applications distributed as part of the GPSTk suite. The GPSTk is sponsored by Space and Geophysics Laboratory, within the Applied Research Laboratories at the University of Texas at Austin (ARL:UT). GPSTk is the by-product of GPS research conducted at ARL:UT since before the first satellite launched in 1978; it is the combined effort of many software engineers and scientists. In 2003 the research staff at ARL:UT decided to open source much of their basic GNSS processing software as the GPSTk. GPSTk Core Library ------------------ The GPSTk core library consist of the most robust, broadly useful, and platform independent code in the GPSTk. It provides a number of models and algorithms found in GNSS textbooks and classic papers, such as solving for the user position or estimating atmospheric refraction. Common formats are supported as well, such as RINEX or SP3. There are several categories of functions in the GPSTk library: 1. Time Representation. Conversion among time representations such as MJD, GPS week and seconds of week, and many others. 2. Ephemeris calculations. Position and clock interpolation for both broadcast and precise ephemerides. 3. Atmospheric delay models. Includes ionosphere and troposphere models. 4. Position solution. Includes an implementation of a Receiver Autonomous Integrity Monitoring algorithm. 5. Mathematics. Includes Matrix and Vector implementations, as well as interpolation and numerical integration. 6. GNSS data structures. Data structures that contain observations mapped according to epochs, satellites, sources and types of observations. Appropriate processing classes are also provided, including a complete 'Precise Point Positioning' (PPP) processing chain. 7. Application framework. Includes processing command lines options, providing interactive help and working with file systems. A more detailed description of the functionality provided by the GPSTk library can be found in the Doxygen documentation on the GPSTk website. The GPSTk Core Library and its associated test programs can be built independently of building the GPSTk Applications or Auxiliary Libraries. The GPSTk Core Library source code contains no dependencies outside of the GPSTk Core Library and Standard C++ and will build cleanly on all supported platforms. GPSTk Applications ------------------ The libraries are the foundation for applications within the GPSTk suite. 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. 1. RINEX utilities - The RINEX utilities provide a set of applications that can be used to examine, manipulate, and plot RINEX observation files. 2. Positioning - The positioning applications include two different applications that perform standard pseudorange-based positioning and two that implement differential phase-based solutions. 3. Residual analysis - A residual analysis application computes two types of measurement residuals using a single receiver or two receivers in a zero baseline configuration. 4. Ionospheric modeling - The ionospheric modeling applications utilize the two frequency TEC estimate from the RINEX utilities and compute a model of the ionosphere. 5. Signal Tracking Simulation - These utilities simulate the tracking of GPS C/A and P-code. 6. Basic transformations - Conversions of time and coordinate systems. 7. Observation data collection and conversion - Translating receiver specific data formats to RINEX. 8. File comparison and validation - Differing observations files against a truth source. 9. Data editing - Simple editing like systematic removal of observations by satellite, type or time and more advanced editing like cycle slip detection and correction. 10.Autonomous and relative positioning - Navigation and surveying applications. The GPSTk applications are dependent on the GPSTk libraries. However, the GPSTk Applications may also contain external dependencies. Some applications may not build or run successfully on all the supported platforms.
