Looking at the DORIS time series, I suggest to put a break at 21-JAN-2002, just
in case the antenna is not exactly back at the same place after the corrosion.
Only 1 position was computed in ITRF2005.
Position in
ITRF2005 was :
2000.0 ASDB
6121161.5600 -1563943.1888
-872613.0551 -4.38 -13.24 10.89
When
looking at DORIS results before 20-JAN-2002 and fixing the velocity I get :
2000.0 ASDB
6121161.5577 -1563943.1891 -872613.0598 -4.38 -13.24 10.89
statistics
ASDB XYZ 0.0028 0.0036 0.0023 140
so there is
an excellent agreement
When
looking at DORIS results after 20-JAN-2002 and fixing the velocity, I get
2000.0 ASD1
6121161.5746 -1563943.1813 -872613.0557 -4.38 -13.24 10.89
statistics
ASD1 XYZ 0.0012 0.0012 0.0009 280
so there
seems to be no need to estmate a different position after the break; We can use
the ITRF2005 position and velocity before and after the break.
Recommendation:
