It has been suggested that probably very few users of
IGS GLONASS orbit products (file types iglWWWWD.sp3)
fail to also use at the same time the associated GPS
orbits for the same week WWWW and day D (files
igsWWWWD.sp3).  So as a convenience to users it is
proposed to change the contents of the igl files to
include *both* GLONASS *and* GPS orbits together.  The
associated igs sp3 files would not be changed in any
way.

We therefore plan to implement such a change starting
with the release of Final products on 01 October 2009.

If any igl users object to such a change or the proposed
implementation date, please contact us to explain how
this would present a problem for you, at:

igs.acc @ noaa.gov

Thanks.
