BELB 66018S001

BEMB 66018S002

 

DM#393 BEMB new station since 21-FEB-2005

 

BEMB is not in ITRF2005

 

Preliminary computations:

 

Local tie from SIMB is

 

BEMB 66018S002 BELB 66018S001 11.387 -77.812 9.579 0.002

 

BELB position in ITRF2005 is

 

BELB 2000.0 1106058.016 -763816.780 -6214233.653 0.39 -10.18 8.64

 

So, using the tie, we get

 

BEMB 2000.0 1106046.629 -763738.968 -6214243.232 0.39 -10.18 8.64

 

From DORIS solution (tf_070515a), fixing the velocity to ITRF2005, we get:

 

2000.0 BEMB 1106046.6312 -763738.9960 -6214243.2244 0.39 -10.18 8.64

statistics BEMB XYZ 0.0010 0.0010 0.0010 63

 

so this is a good control, difference is (in XYZ-mm) = 2 -28 8

 

From more recent DORIS solution (ign07d02), by fixing the velocity we get :

 

2000.0 BEMB 1106046.6478 -763738.9621 -6214243.2456 0.39 -10.18 8.64

statistics BEMB XYZ 0.0013 0.0009 0.0013 103

 

And for BELB, we have :

 

2000.0 BELB 1106058.0141 -763816.7799 -6214233.6496 0.39 -10.18 8.64

statistics BELB XYZ 0.0033 0.0037 0.0035 7

 

So both ITRF2005 positions (BELB and BEMVB) can be directly adopted

 

Recommendation:

 

BEMB derive ITRF2005 coordinate, using BELB + geodetic local tie with control of recent DORIS results

BEMB 2000.0 1106046.629 -763738.968 -6214243.232 0.39 -10.18 8.64
