Key facts
Contents & fields
Data from a NovAtel GPStation-6 GISTM receiver at Troll station, Antarctica, recording GPS, GLONASS, and Galileo satellite signals. One-minute extended summary messages include the following fields:
- Satellite azimuth/elevation——Azimuth and elevation angles of the satellite
- C/N0——Carrier-to-noise ratio
- Lock time——Signal lock duration
- Code-minus-carrier——Difference between code phase and carrier phase
- S4——Amplitude scintillation index
- σφ——Phase scintillation index
Data are stored as tables in .txt files, each containing data and a header.

Why this is hard to get on your own
When obtaining high-temporal-resolution ionospheric scintillation observations in polar regions, issues such as inconsistent data formats and missing field descriptions are common.
