BETB
50305S001
DM#466
BETB new station since 22-OCT-2006
BETB is not
in ITRF2005
The
position/velocity proposed in the DORISMail is (in ITRF2000) and at epoch
2000.5
BETB 2000.5
-6327823.264 785599.310 149786.287 6.5 68.9 29.1 (in ITRF20000)
This can be
transformed at epoch 2000.0 (in ITRF2000)
BETB 2000.0
-6327823.267 785599.276 149786.272 6.5 68.9 29.1 (in ITRF20000)
And then in
ITRF2005
BETB
2000 .0 -6327823.256 785599.282 149786.276 5.79 68.85 31.04
Preliminary
computations:
Using
ITRF2005 plate model, we get the following velocities (DX DY DZ = 9.06 67.21
30.32)
Using the
recent DORIS data (ign07d02) and fixing the velocity to ITRF2005 value, we get
:
2000.0 BETB
-6327823.2918 785599.2682 149786.3038 9.06 67.21 30.32
statistics
BETB XYZ 0.0027 0.0023 0.0013 57
this is
close to the value derived from the DORISMail
