EUREF Permanent GNSS Network

The Overview tab contains the following metrics:

Proposed Satellite Systems: Satellite systems indicated in the site log
Meta-data: when the headers of daily RINEX v2 and RINEX v3 (if available) are consistent with the station site log
Documentation
- SL (Site log): when site log has been validated and submitted to the EPN CB
- CL (Commitment Letter): when Commitment Letter has been received by the EPN CB
- SP (Site Pictures): when site pictures have been submitted to the EPN CB
- DL (Data License): data license which has been chosen on M3G
Data
- Quality: when "Average ratio" is larger than 90 % ( between 80% and 90%). Average ratio (%) is the average of the ratios of the number of dual freq. of observations wrt. the number of expected obs. (for RINEX v2 and v3 - if available) taken over the last 28 days with the G-Nut/Anubis software.
- Availability:
  - BEV/BKG: when the % of existing hourly (resp. daily) RINEX (v2 and v3) observ. files over the last 7 days (resp. 28 days) is larger than 90% ( between 80% and 90%).
  - #BRDC: when the number of regional EPN broadcasters receiving the real-time data equal to 3 ( when 1 or 2).
- Latency:
  - BEV/BKG: when the % of hourly RINEX (v2 and v3) observ. files that is made available at the data centers within 10 minutes over the last 7 days is larger than 90% ( between 80% and 90%).
Interested Analysis Centres: Analysis Centres willing to process the data, at least three are required.
Ready: "yes" when the EPN guidelines are satisfied. This means that the station is ready to be included in the EPN.

Data Quality percentages are computed over last 28 calender days with the G-Nut/Anubis software (Václavovic P, Dousa J (2016), G-Nut/Anubis - open-source tool for multi-GNSS data monitoring, In: IAG 150 Years, Rizos Ch. and Willis P. (eds), International Association of Geodesy Symposia, Springer, Vol. 143, pp. 775-782, doi:10.1007/1345_2015_97)

Dual+ frequency obs. count: percentage of number of obs. on at least two frequencies wrt of number of expected obs.
All observations count: percentage of number of obs. wrt of number of expected obs.

Color codes: at least 90%, between 80% and 90%, less than 80%
