Geomagnetic Information Nodes
The Geomagnetic Information Nodes (GINs) are the collection
points for real-time data within INTERMAGNET. They are connected to the
INTERMAGNET observatories by satellite, computer
and telephone networks. Minute mean observations of the earth's magnetic
field are relayed to the GINs within 72 hours of recording. This time
is substantially reduced when observatories are using satellite communications.
