Dear Mr Belem,

	If you need the coordinates for the stations YKRO and MAS1
to connect your local station to ITRF2005, you could use
the IGS coordinates for the GPS week 1562 (09/12/13 - 09/12/19).
You can find those at:

ftp://cddis.gsfc.nasa.gov/pub/gps/products/1562/igs09P1562.snx.Z

For that week, the two stations of interest have the following coordinates
as extracted from the file "igs09P1562.snx":
   499 STAX   MAS1  A    2 09:350:86390 m    2 .54391922020441787E+7 .3479627E-2
   500 STAY   MAS1  A    2 09:350:86390 m    2 -.1522055393850000E+7 .1407953E-2
   501 STAZ   MAS1  A    2 09:350:86390 m    2 .29534549307874274E+7 .2004772E-2

  1060 STAX   YKRO  A    2 09:350:43192 m    2 .63064399791285284E+7 .4649563E-2
  1061 STAY   YKRO  A    2 09:350:43192 m    2 -.5783807626777582E+6 .1415774E-2
  1062 STAZ   YKRO  A    2 09:350:43192 m    2 .75795651438999665E+6 .1309660E-2

Those are aligned to the IGS realization of ITRF2005 at the epoch
~~ 2009/12/16. If needed, the file also contain the full covariance
information, as well as other auxiliary information.

If your actual solution epoch best match another week feel free
to use either the preceding or the following week.

Best Regards,
Remi,
