Daily raw and RINEX format GPS files from field campaign observations at sites in the Antarctic Peninsula and southern South America between 1997 and 2002. Most observations were recorded at a thirty second interval and spanned at least two complete UTC days, using dual frequency GPS receivers and choke ring antennae. The data are archived by UNAVCO and grouped by year.
Use Cases
- Analyze tectonic plate motion based on GPS coordinate measurements
- Study crustal deformation rates based on repeated campaign observations
- Validate satellite-derived geodetic models based on ground-based GPS data
- Assess monument stability based on measurements from stainless steel pins in bedrock
Strengths
- Data spans a five-year period from 1997 to 2002
- Most observations were recorded at a thirty second interval
- Dual frequency GPS receivers and choke ring antennae were normally used
- Data is grouped by year in the UNAVCO archive for organized access
Limitations
- Last updated 2002-12-17 23:59:59.999000; freshness should be verified
- Column-level documentation is absent; field semantics must be inferred after download
- Row count is unknown, which may limit suitability assessment
