Satellites orbiting the Earth at an elevation of 25,000 miles relay data
messages from remote collection sites to Reclamation's downlink facility located in Boise, Idaho.
These are the same satellites that provide 'Satellite Weather Images' on the television news.
Hydromet uses the GOES-9 and DOMSAT satellites, and to a lesser degree, the GOES-8 satellite.
NASA provides backup data recieve and retransmission services via the DOMSAT satellite system. DOMSAT
messages and atomic clock time synchronization signals are also received at the Boise downlink
