Preliminary
computations:
FAI before
01-JAN-1996
ITRF2005
solution is
2000.0 FAIA
-2282503.1445 -1453417.0242 5756694.5027 -21.07 -4.71 -3.93
Using DORIS
weekly solutions (ign07d02) expressed in ITRF2005 and fixing the velocity to
the above value, we obtain :
2000.0 FAIA
-2282503.1389 -1453417.0336 5756694.5017 -21.07 -4.71 -3.93
statistics
FAIA XYZ 0.0015 0.0017 0.0017 156
so this is
in good agreement with the ITRF2005 value
For FAIA
after 01-JAN-1996
ITRF2005
solution is
2000.0 FAIA
-2282503.1421-1453417.0167 5756694.4958 -21.07 -4.71 -3.93
Using DORIS
weekly solutions (ign07d02) expressed in ITRF2005 and fixing the velocity to
the above value, we obtain :
2000.0 FAI1
-2282503.1412 -1453417.0287 5756694.4949 -21.07 -4.71 -3.93
statistics
FAI1 XYZ 0.0014 0.0017 0.0017 175
so this is
in good agreement with the ITRF2005 value
For FAIB
before the Earthquake (03-NOV-2002)
ITRF2005
solution is
2000.0 FAIB
-2282578.7904 -1453178.9032
5756712.2136 -22.01 -6.23 -7.62
Please note
that the ITRF2005 velocities are different for FAIA and FAIB
Using DORIS
weekly solutions (ign07d02) expressed in ITRF2005 and fixing the velocity to
the above value, we obtain :
2000.0 FAIB
-2282578.7863 -1453178.9126 5756712.2108 -22.01 -6.23 -7.62
statistics
FAIB XYZ 0.0013 0.0016 0.0015 147
so this is
in good agreement with the ITRF2005 value
For FAIB
after the break on 02-NOV-2002
ITRF2005
solution is
2000.0 FAIB
-2282578.7931 -1453178.9379
5756712.1933 -27.85 -10.75 -4.05
Using DORIS
weekly solutions (ign07d02) expressed in ITRF2005 and fixing the velocity to the
above value, we obtain :
2000.0 FAI2
-2282578.7844 -1453178.9430 5756712.1836 -27.85 -10.75 -4.05
statistics
FAI2 XYZ 0.0009 0.0006 0.0007 271
so this is
in good agreement with the ITRF2005 value
Recommendation:
Use ITRF2005 values
