JavaScript must be enabled in order for you to use Google Maps. However, it seems JavaScript is either disabled or not supported by your browser. To view Google Maps, enable JavaScript by changing your browser options, and then try again.

All stations proposed to the EPN should follow the procedure for becoming an EPN station and guidelines for EPN stations and operational centres.

Data Quality (based on TEQC)

0°: % of dual frequency GPS data above 0° of elevation
(at least 90%, between 80% and 89%, less than 80%)
15°: % of dual frequency GPS data above 15° of elevation
(at least 90%, between 80% and 89%, less than 80%)

Availability (adopted data flow for the station data)

Daily: data available (%) during the last 28 days
(at least 90%, between 80% and 89%, less than 80%)
Hourly: data available (%) during the last 28 days
(at least 90%, between 80% and 89%, less than 80%)
RT: data available (%) during the last 7 days
(at least 90%, between 80% and 89%, less than 80%)

Latency

Hourly: % of data with latency below 10 minutes during the last 7 days
(at least 90%, between 80% and 89%, less than 80%)
RT: data latency (%) during the last 7 days
(below 3 s, between 3 s and 4.9 s, more than 5 s)

Documentation

CL: commitment letter available at EPN CB
SL: correctly formatted station log available at EPN CB
SP: station pictures (and short comments) available at EPN CB
NC: national ETRF coordinates available at EPN CB

Meta-data

Daily: station log and header of RINEX observation file are consistent
RT: station log and RTCM messages are consistent

Relevance to EPN

The EPN Coordination Group will evaluate the benefits of a proposed station to the EPN (see EPN Guidelines). Possible added-values are :

D: densification station (no existing EPN station within a radius of 300 km)
R: offering GLONASS (Russian satellite system) data in addition to GPS
E: offering GALILEO (European satellite system) data in addition to GPS
C: collocation with a relevant instrument

Data

AC: antenna (+radome) has absolute calibration values known to IGS/EUREF
DQ: GNSS data quality responds to EPN standards (cut off, obstructions, ...)
