We are pleased to announce the release of version 1.2 of the GPSTk. This release provides library enhancements and a number of new applications. In addition, we are providing precompiled binaries for Windows, Linux and Solaris. This is the first release under our new development process. In addition, this release coincides with the establishment of a new, TWiki-based website for the GPSTk.

New Features

In the interests of brevity, the changes to the GPSTk since version 1.1 will not be described in this announcement. See the attached ChangeLog for a full description.

Binary Packages

Precompiled binaries are provided as downloadable packages, available through the SourceForge download service. For Windows users, an MSI installation package is provided. For Solaris/SPARC32 and Linux/x386, the packages are 'tarballs' -- gzipp'ed, tar'ed files. Note that the Linux binaries are statically linked, where the Solaris binaries are dynamically linked.

Development Process

Early this year, we established a public repository for the GPSTk on SourceForge using their Subversion service. This is the only repository for the GPSTk code. GPSTk version 1.2 corresponds to Subversion release 351. Interested users, who are willing to compile the GPSTk, can acquire the latest version of the GPSTk using the Subversion utility. More information on the use of Subversion is available through the GPSTk website.

For the last few months we have developed a testing process based on CppUnit. This allows deep testing of individual classes in the GPSTk library. While this testing currently only checks 40% of the library, the plan is to expand coverage with each new release.


In an effort to provide a dynamic website, as well as a means for collaborative development, the old GPSTk website has been retired and replaced with a Wiki (http://en.wikipedia.org/wiki/Wiki). The implementation used for the website is TWiki (http://www.twiki.org). While the current content is similar to that of the older site, with corrections, this content is now easier to modify. Quoting the TWiki site,

"[Using TWiki,] web content can be created collaboratively by using just a browser. Users without programming skills can create web applications."

A detailed guide specific to the GPSTk Wiki is under development. A later posting to gpstk-announce will describe the new website and detail its features.
