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.
|
||
|
|
|
||
|
|
|
||
|
|
The GPSTk library provides the base functionality for the GPSTk
|
||
|
|
applications and for a number of other independent projects. There are
|
||
|
|
several categories of functions in the GPSTk library:
|
||
|
|
|
||
|
|
1. GPS time. 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. Application framework. Includes processing command lines options,
|
||
|
|
providing interactive help and working with file systems.
|
||
|
|
|
||
|
|
|
||
|
|
The GPSTk 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. Basic transformations. Conversions of time and coordinate systems.
|
||
|
|
|
||
|
|
2. Observation data collection and conversion. Translating receiver
|
||
|
|
specific data formats to RINEX.
|
||
|
|
|
||
|
|
3. File comparison and validation. Differing observations files against
|
||
|
|
a truth source.
|
||
|
|
|
||
|
|
4. Data editing. Systematic removal of observations by satellite, type
|
||
|
|
or time.
|
||
|
|
|
||
|
|
5. Ionosphere modeling. Basic models of the ionosphere.
|
||
|
|
|
||
|
|
6. Autonomous and relative positioning. Navigation and surveying
|
||
|
|
applications.
