Dear Colleagues,
The stability of the support of the DORIS antenna at Cibinong has been improved, by building a concrete pillar around the current 3 m tower which was used as a reinforcing structure for this pillar. The pillar is supported by a huge underground pyramid-shaped concrete block: 2.5 m deep, 1.6 m sided base.

The Starec antenna which was initially installed in 1992 has been replaced with a new one. Since the antenna height is slightly different, a new acronym has been assigned to the reference point : CICB.

Transmissions from the former antenna stopped on December 11, and resumed from the new one on December 12.

The DOMES number for the new antenna reference point is 23101S002.

Its approximate coordinates (ITRF97, 1997.0) are:
X =  -1836963.60 m      Y = 6065626.77 m        Z = -716217.29 m
(sigma: 2 cm)

Season's greetings and best regards,

Herve Fagard
