This is a repository of GNATSS processing examples and test data sets. It was developed for a GNSS-A short course in conjunction with the Near-Trench Community Geodesy Experiment, funded by NSF.
Global Navigation Satellite Systems - Acoustic (GNSS-A) is a seafloor geodetic technique that combines acoustic ranging of an array of seafloor transponders with GNSS in order to position points on the seafloor with ~cm level horizontal accuracy.
GNATSS is an open-source software for processing GNSS-A data for seafloor horizontal positioning. For more information on how to install and run GNATSS, click here.
The Near-Trench Community Geodetic Experiment is an NSF-funded project tasked with expanding our offshore geodetic coverage of the Cascadia and Alaska subduction zones as well as building the seafloor geodetic user base by making these data freely available and developing tools for their analysis.

The exercises hosted in this repository may be accessed via GitHub Codespaces - "a development environment that's hosted in the cloud". In order to access the Codespace, you need to register an account with GitHub.
Exercises may be run via Jupyter notebook or on the command line interface. An overview for them is also hosted at gnatss-workshop.readthedocs.io.

GitHub currently gives every user 120 vCPU hours per month for free, beyond that you must pay. So be sure to explicitly stop or shut down your codespace when you are done by going to this page (https://github.com/codespaces).
