The Gpstk: Glonass, Rinex Version 3.00 And More

The GPS Toolkit (GPSTk) project is an attempt to bring the power of the open source world to the satellite navigation community. The GPSTk is intended to help eliminate the "black box" nature of many commercial applications, and to enable rapid prototype development for data analysis applications. It is also intended to support software development and systems engineering associated with GNSS data collection systems.Because satellite navigation is ubiquitous, its users employ practically every computational architecture and operating system. Therefore the GPSTk suite is intended to be as platform-independent as possible. This is achieved through use of ISO-standard C++. The principles of object-oriented programming are used throughout the GPSTk code base in order to ensure that it is modular, extensible and maintainable.The software suite consists of a core library, auxiliary libraries, and a large set of advanced applications. The libraries provide the wide array of common functions that applications use to handle data processing associated with GPS. Furthermore, programmers can also access the library code to develop new processing applications.The GPSTk was initially designed and developed in a highly collaborative environment of software engineers and scientists in the Space and Geophysics laboratory (SGL) at the Applied Research Laboratories, The University of Texas at Austin (ARL:UT). SGL decided in 2003 to open-source much of their basic GPS processing software as the GPSTk under the GNU Lesser General Public License (LGPL) version 2.1. The GPSTk's source code and documentation are now hosted on public servers so that project members from multiple academic and commercial institutions can freely collaborate in development.In the last two years, a number of new applications and library capabilities have been added to the GPSTk. New applications have been added to characterize clock stability. New library capabilities have been added to process GLONASS observations and to fully support the Receiver INdependent EXchange (RINEX) version 3 file format. New library code also provides the ability to generate highly customizable plots compatible with LATEX and web browsers. A new library has been added that provides a framework for precise point positioning (PPP).
