NEDA operational control : is provided by RDAAC : Acquisition/Analysis Center (Moscow, Russia). : RDAAC is also IGS Operational Center for NEDA. : ******************************************* : The GPS reference mark consists of : 5/8-11" diameter, vertical stainless steel rod. : It is glued into the concrete parapet at : the southwestern corner of the roof of : Seismic Station Yakutsk. This is 2-story : building made from prefabricated concrete. : The rod is driven into the parapet to a depth : of 100 mm; its top end is 100 mm above : the surface of the parapet. : Vertical datum : of the rod. Antenna is attached to the rod : with the UNAVCO compact leveling mount. : The antenna and choke ring assembly are : protected with the SCIGN hemispherical dome. : Mark YAKT is located 37 m to the west of : IGS mark YAKZ (IERS DOMES No. 12353M001). : YAKT was reoccupied several times : since 1996 and showed much smaller seasonal : horizontal fluctuations compared with YAKZ. 2.
