[IGSSTATION-4894] WLSN: receiver and antenna change

[David Maggert]

Dear Colleagues,

The USGS replaced the receiver and antenna at the Mt. Wilson (WLSN) IGS 
station back in April 2011.  Upon installation of the new antenna on 
April 29th, 2011, there was trouble placing the antenna onto the mount 
properly which caused the antenna height to be 13mm higher than the 
previous antenna.  On June 7th, 2011, the top base plate was machined 
and the Topcon antenna was properly installed on the antenna mount and 
the antenna resumed its original antenna height of 0.061 meters.  An 
updated site log has been posted at the IGSCB.

Data publication will resume tomorrow and 02-MAY-2011 until 29-APR-2012 
data will be published.  Unfortunately, the USGS is currently unable to 
download the data from the receiver on a daily basis.  They are working 
to restore this capability.

This station is operated and maintained by the USGS.

Best Regards,
David Maggert
