Dear Colleagues,

A number of you have voiced concern over the quality of data from the 
North Liberty, Iowa (NLIB) GNSS station.  The station has a broken dome 
and an aging AOA choke ring antenna which needs to be replaced.  In 
order to upgrade the equipment, a new mounting system had to be 
designed.  This has been a complex problem for a number of reasons.  We 
have been working on this issue for the past few months and are 
currently waiting for the second prototype to be fabricated.  Our hope 
is to upgrade the station by mid to late October.  We apologize for any 
inconvenience this has/or may cause.

Maintenance and operations of the NLIB station is a collaborative effort 
supported by JPL, UNAVCO, and the National Radio Astronomy Observatory, 
North Liberty Iowa with funding provided by NASA's Earth Surface and 
Interior Focus Area - Science Mission Directorate.

Best Regards,
Victoria Andreatta
