DM#474
HBMB new station since 22-NOV-2006 + (HBKB = HBLB)
HBMB not in
ITRF2005
Preliminary
computations:
Geodetic
local tie from SIMB is
HBMB
30302S008 HBKB 30302S006 -0.138 -0.075 0.075 0.001
HBMB
30302S008 HBLA 30302S005 -11.971 2.687 -26.814 0.002
So, we have
HBMB
HBLA in
ITRF2005 is
HBLA 2000.0
5084641.470 2670349.993 -2768497.791 0.03 19.92 16.41
So, we
derive
HBMB 2000.0
5084653.441 2670347.306 -2768470.977 0.03 19.92 16.41
DORIS-derived
position (tf_070515a) using fixed ITRF2005 from HBLA gives
2000.0 HBMB
5084653.4912 2670347.2740 -2768470.9840 0.03 19.92 16.41
statistics
HBMB XYZ 0.0067 0.0077 0.0051 6
There is
just 6 weeks of DORIS but the difference is quite significant.
Requires
further investigation XYZ/mm +187 +43 -82
With more
recent DORIS data (ign07d02) and fixing the velocity to ITRF2005, we get
2000.0 HBMB
5084653.4663 2670347.3021 -2768470.9889 0.03 19.92 16.42
statistics
HBMB XYZ 0.0022 0.0024 0.0017 46
so it is in
good agreement with ITRF2005
