AJAB

JoG: AJAB
should not be used for ITRF2005, too few data
IDS :
AJAB should not be used for ITRF2005, too few data
ITRF: AJAB
is not in ITRF2005
Preliminary
computations:
No AJAB
data left in computation. Need for other source of information, for example
transforming previous DPOD2000 (ITRF2000) coordinates/velocity into ITRF2005
Position in
dpod2000_2 in 1997.0 was
AJAB 1997.0 4696990.16 723981.10 4239679,21 -12.9 19.7 10.9
So in ITRF2000 at epoch 2000.0 we get
AJAB 2000.0 4696990.121
723981.160 4239679.243
-12.9 19.7 10.9
When
transforming from ITRF2000 into ITRF2005, I get
AJAB 2000.0
4696990.103 723981.156 4239679.246 -12.77 19.58 12.79
Reprocessing
the 5 weeks of AJAB data (Februray-March 2002) and fixing the velocity to the
above values, I obtain at epoch 2000.0
2000.0 AJAB
4696990.1210 723981.1692 4239679.2237 -12.77 19.58 12.79
statistics
AJAB XYZ 0.0158 0.0190 0.0123 5
This is an
excellent agreement, knowing that I test the position outside the observation
period.
Recommendation:
No change for AJAB; should not be used; retain JoG coordinates
