Community Seafloor Global Navigation Satellite Systems - Acoustic (GNSS-A) Transponder Surveying Software Workshop
Abstract¶
This workshop is a short course developed as part of the Near-trench Community Geodetic Experiment, supported by the National Science Foundation, intended to provide an introduction to analyzing Global Navigation Satellite Systems - Acoustic (GNSS-A) data. This workshop will provide a practical introduction to GNATSS, an open-source software for processing GNSS-A data for seafloor horizontal positioning, including how to install and use the software to process GNSS-A data.
Learning Goals:¶
Building strong understanding of GNSS-Acoustics for precise point positioning with a focus on the newly collected data associated with the Community Experiment, including:
- Deployment strategies
- Instrument operations
- Data collection and standards
- Data access
- Processing data using the new GNATSS software
Network with other researchers who share common interests
