Subject: Network/ station renovation at Krasnoyarsk

DORISMail version 1.1
Subject: No 0641 : Network/ new point at KRASNOYARSK 
#### END HEADER ####

Dear colleagues,

The DORIS station "Krasnoyarsk" (Russia) has been down since late 2005. The
necessary site renovation and equipment replacement were not carried out
because of delays in paperwork (custom clearance of equipment…).

After this very long wait, the equipment was eventually installed in late
October 2009. 

The beacon is now a third generation one.

The antenna has been moved to a new support in order to improve its
stability. The antenna is now supported by a 1 meter high, 30 cm sided very
rigid metal tower, set on top of a 50 cm sided concrete block, standing on a
corner of the terrace roof of the building. This new location is about 20 cm
away from the former one.

The acronym for the new reference point is KRBB and the transmissions from
the new beacon and new antenna position started on October 24, 2009.

Please find below the installation characteristics and the coordinates of
the new reference point resulting from the geodetic connection to the former
antenna KRAB:
