KETB new station since 11-APR-2007
IDS KESB
break on 01-JAN-2004
ITRF KESB
break on 01-JAN-2004
KETB is not
in ITRF2005
Preliminary
computations:
KESB in
ITRF2005 (before the break) is:
KESB 2000.0
1406334.550 3918142.337 -4816185.054 -5.73 -0.10 -5.84
KESB in
ITRF2005 (after break is called KES1) is
KES1 2000.0
1406334.522 3918142.353 4816185.043 -5.73 -0.10 -5.84
So the
break is significant (3 cm in X)
From
geodetic local tie, we have
KETB
91201S005 KESB 91201S004 -0.069 -0.197 0.240 0.001
In
ITRF2005, we have
KESB 2000.0
1406334.550 3918142.337 -4816185.054 -5.73 -0.10 -5.84
So, we
obtain
KETB 2000.0
1406334.619 3918142.534 -4816185.294 -5.73 -0.10 -5.84
DORIS
solution (tf_070515a) using ITRF2005 fixed velocity is not yet possible (no
data yet)
Using more
recent DORIS data (ign07d02)
2000.0 KETB
1406334.6067 3918142.5539 -4816185.2663 -5.73 -0.10 -5.84
statistics
KETB XYZ 0.0028 0.0017 0.0014 35
good
agreement
Need
further investigation
