Quebec GNSS Station Network Data in RINEX Format

GNSS data from a network of 18 stations across Quebec, capturing signals from GPS, GLONASS, and Galileo constellations. Data is provided in the Receiver Independent Exchange Format (RINEX) version 2.11 and is accessible for the last 366 days.

Use Cases

• Analyze RINEX observation files from 18 stations to model ionospheric conditions affecting signal accuracy.
• Process GNSS station data with known NAD 83 (SCRS) coordinates to perform differential corrections for centimeter-level positioning.
• Use time-series data from the continuous network to assess signal availability and accuracy variations across GPS, GLONASS, and Galileo constellations.

Strengths

• Data is collected from 18 dedicated GNSS stations on geodetic points free of obstacles.
• Uses the standardized RINEX 2.11 format compatible with most GNSS processing software.
• Provides real-time data access via cellular telephony for centimetric positioning work.

Limitations

• Data availability is limited to the last 366 days, restricting long-term temporal analysis.
• Sample data and specific column structures for the RINEX files are not provided in the description.
• Real-time data accuracy depends on variable factors like telephone coverage and ionospheric conditions.
