Data available at SONELTGDE

                (Norwegian Mapping Authority)

The Norwegian Mapping Authority provides RINEX data from these stations 
to SONEL: 

- AND1 (Andenes tide gauge)
- FROC (Froeya/Mausundvaer GNSS)
- HONS (Honningsvaag GNSS)
- TGDE (Tregde tide gauge)
- VAR1 (Vardoe tide gauge)
- VIKC (Vikna GNSS/Roervik)


Data are delivered in daily files, 30-second data rates with a 25 day 
delay. The data are intended for non-commercial research or education 
use only. Commercial use is not allowed. 

Please inform Norwegian Mapping Authority by email 
 if these data are used in published research. 

The data are provided as-is, free of charge for the intended uses. The 
Norwegian Mapping Authority gives no guarantee of and assumes no 
responsibility for the accuracy, completeness or usefulness of any data. 
In particular, VAR1 is known to have an annual north-south oscillation. 

SONEL also collects data from NMA GNSS stations published via EUREF and 
IGS. Different conditions apply to these stations. 

Contact NMA Control Centre for positioning services at 
 for questions or further info.
