The goal of the GPSTk project is to provide a open source library and suite of applications to the satellite navigation community--to free researchers to focus on research, not lower level coding.

The GPSTk suite consists of a core library and a set of applications. The library provides a wide array of functions that solve processing problems associated with GPS such as processing or using standard formats such as RINEX. The library is the basis for the more advanced applications distributed as part of the GPSTk suite.
