A new antenna adapter : was installed on 16 August 2006 to raise the : antenna above the new parapet on the roof. A : new DOMES number and 4-character ID were : obtained, referring to the on-axis point where : the mast meets the adapter. The position of : UNBJ ARP was approximately 0.227 m above UNB1 : ARP with Javad antenna. Antenna changed to : TRM57971.00 on 1 June 2012. Note new : top-of-mast to ARP/BAM value in graphic below. : Previous Javad antenna was likely not : JPSREGANT_DD_E but rather the JPSREGANT_DD_E1 : variant with an estimated 18 mm vertical PCO : with respect to JPSREGANT_DD_E. : Previously, a NovAtel OEMV receiver was : operated as UNBN. However, data from this : receiver was never formally supplied to IGS. It : was used by some research organizations : including the Center for Orbit Determination in : Europe.
