ADEA 91501S001

ADEB 91501S002

ADFB 91501S003

 

ADEA and ADEB are in ITRF2005

 

2000.0 ADEA -1941059.6367 1628659.2680 -5833613.5065 0.44 -14.43 -4.84

 

2000.0 ADEB -1940878.4013 1628473.0097 -5833723.0135 0.44 -14.43 -4.84

 

ADFB is a new station #DM533

 

Preliminary computations:

 

For ADFB, the DORISMail provides the following geodetic local tie

 

The vector from ADEB to ADFB is:

dN = 0.000 m dE = -0.001 m dh = 0.404 m.

 

So, ini XYZ

 

ADEB --> ADFB -0.122 0.104 -0.371

 

As ADEB is

 

2000.0 ADEB -1940878.4013 1628473.0097 -5833723.0135 0.44 -14.43 -4.84

 

so, we derive :

 

2000.0 ADFB -1940878.523 1628473.114 -5833723.385 0.44 -14.43 -4.84

 

Using the first available DORIS data (12 weeks), we obtain the following coordinates, if we fix the velocity to ITRF2005

 

2000.0 ADFB -1940878.5221 1628473.1341 -5833723.4057 0.44 -14.43 -4.84

statistics ADFB XYZ 0.0025 0.0024 0.0018 12

 

so this is a good confirmation of our coordinates

 

Recommendation:

 

Use ITRF2005 solution for ADEA and ADEB

 

Derive ADFB from ADEB and use fiirst DORIS data to verify
