EPN station tracking performance:

The plots below show only the last year of the data quality information. The full history of the data quality information can be viewed here (be patient: it needs time to load).
The monthly skyplots are available here.
The comparison with other stations is available here.

The plots below present the long-term tracking performance of PDEL00PRT (Ponta Delgada, Portugal). The numbers are obtained using the G-Nut/Anubis software (versions 2.2.1, 2.2.4 and 2.3.0 beta), developed by the Geodetic observatory Pecný, Czech Republic. Input files are the daily RINEX 2 and RINEX 3 (if available) observation files. Only healthy satellites are taken into account (even if tracking unhealthy satellites is still recommended). For RINEX 2, only and GPS and GLONASS data are considered.

Warning! Several G-Nut/Anubis software versions are used:
  • Before 2019-03-05: version 2.2.1
  • Between 2019-03-05 and 2019-09-01: version 2.2.4
  • After 2019-09-01: version 2.3.0 beta
