Given the difficulty to access this remote area, the local tie survey will be carried out later. For the time being, we consider that the coordinates are unchanged. > to summarize: > The transmissions from the former antenna location (ADFB) stopped on May 30, 2011 > ADFB DOMES 91501S003 > ITRF2005 Epoch 2000.0 > X= -1940878.523 m Y= 1628473.114 m Z= -5833723.385 m > SigX = 0.001 m SigY = 0.001 m SigZ = 0.002 m > The ITRF2005 velocities for this site are : > VX = 0.00044 m/y VY = -0.01443 m/y VZ = -0.00484 m/y > SigVX = 0.0003 m/y SigVY = 0.0003 m/y SigVZ = 0.0003 m/y > > The transmissions from the new antenna (ADGB) began on May 30, 2011 > Remaining in the expectation of the survey > ADGB DOMES 91501S004 > ITRF2005 Epoch 2000.0 > X= -1940878.523 m Y= 1628473.114 m Z= -5833723.385 m > SigX = 0.005 m SigY = 0.005 m SigZ = 0.005 m > The ITRF2005 velocities for this site are : > VX = 0.00044 m/y VY = -0.01443 m/y VZ = -0.00484 m/y > SigVX = 0.0003 m/y SigVY = 0.0003 m/y SigVZ = 0.0003 m/y > > SigX, SigY and SigZ only changed > Best regards, Pascale FERRAGE _____________________________________________________ CNES - International DORIS Service (IDS): http://ids-doris.org/ DCT/ME/OT- Bpi 612 Phone : 33 - (0)5 61 28 30 66 18, avenue Edouard Belin Fax : 33 - (0)5 61 28 25 95 31 401 TOULOUSE CEDEX 9 Email : Pascale.ferrage@cnes.fr _____________________________________________________
