Timing system: All telemetered stations record WWVB directly. CCU uses a Geotech TG-llO. DUG uses WWSSN standard. FCU uses a
Simplex Model 25. SLC uses a Geotech 19000.

SHORT HISTORY
CCD operated by Southern Utah State Col i ege tor the Dnlverslty 0' utah.
UEO wa"
'"
formerly run by AFTAC and w'" "et up like BMO with a 10-station array. It, equipment and array pattern were
identical to those of HMO.
LOG was owned and operated by the Utah State Agricultural College from 1940 to January 1964 when the University of Utah
assumed responsibility foe the station.
SLU was originally established in 1939 at a slightly different location from the current one.
FGU was operated by USC&GS foe the U,S. Bureau of Reclamation until it was given to the University in July 1970.
Stations along the Wasatch Front were supported largely by USGS grants.
