Subject: updated coordinates for BELB, CROB, JIUB and others

Dear all,

in case somebody wants to use those, here are some updated 
coordinates for the recent DORIS stations BELB, CROB and JIUB and 
others.

Coordinates are expressed in ITRF2000 at epoch 04APR01

In parenthesis is the number of observed weeks available. This 
computation only the last available 20 weeks

BELB (7 weeks)
    1106058.064 +- 0.005
    -763816.817 +- 0.004
   -6214233.621 +- 0.004
CADB (5 weeks)
    4163471.772 +- 0.013
   -4163826.172 +- 0.013
   -2444514.563 +- 0.010
CROB (15 weeks)
    2719992.115 +- 0.004
    3463401.951 +- 0.003
   -4598608.148 +- 0.004
GAVB (28 weeks)
    4783636.535 +- 0.004
    2140697.614 +- 0.005
    3623255.314 +- 0.005
JIUB (8 weeks)
   -2279839.455 +- 0.014
    5004701.603 +- 0.011
    3219776.011 +- 0.011
MSPB (5 weeks)
   -4467071.238 +- 0.016
    2683028.299 +- 0.016
   -3667004.149 +- 0.014
YASB (24 weeks)
   -2389016.787 +- 0.004
    5043346.257 +- 0.003
   -3078493.325 +- 0.003

velocities estimates were provided by Herve Fagard in the DORISMails 
#306 (BELB), and #283 (JIUB) but not for CROB.

During the recent IDS meeting in early May, it was suggested to have 
a file containing a priori coordinates and velocities in ITRF2000 at 
1-2 cm precision for recent DORIS stations that were not available 
for the ITRF2000 release. This could be a start of such a file.

Best regards
Pascal
