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.
