Do you need help with any of the software topics listed here?

• Request Support for:

• Software Bugs on software in this section have been found, you have the problem(s) well documented, and you would like to report them.

• Feature Enhancement — Perhaps you would like to request or suggest new functionality for a particular software at UNAVCO.

For various pre-processing or post-processing of GPS/GNSS and TLS data:

• TEQC (Translation, Editing and Quality Checking) — GPS/GNSS format translating, correct GPS/GNSS metadata, time window or perform other filtering, and/or GPS/GNSS quality check.

• GPS/GNSS Pre-processing Tools —Hatanaka, Trimble's runpkr00, and other pre-processing tools for various tasks

Data management sofware subsystems for regional geodesy data managers are available.

• GSAC — Geodetic Seamless Archive Center, a free, open-source software package that provides web services for discovery, sharing, and access to geodetic data and metadata associated with site-located instruments.

To assist all levels of users, visualization and mapping tools are available through UNAVCO. These applications allow users to display data for individual or small groups of data points in a variety of ways.

• GPS Velocity Viewer allows exploration of PBO-site geodetic plate velocities, or your own geodetic velocities, in various reference frames.

• Jules Verne Voyager — a Java applet to access server-side map creation with editions for virtual exploration of:

• Earth and PaleoEarth,

• the Global Strain Rate Model,

• and other worlds.

• 
  

Modeling software, written by community members, allow users to test geophysical models that would give rise to various observations, such as GPS/GNSS site motions.

Geodetic utilities provide supporting information associated with geodetic positioning.

• Plate motion calculator calculates rigid plate motions at one or more specified locations on Earth using one or more plate motion models.
