Dear colleagues,

The macromodels documents for Spot2, Spot3, Spot5, and Envisat have been update= d on the IDS ftp:

Spot2 and Spot3  = ftp://ftp.cls.fr/pub/ids/satellites/macromodels/spot2mod.pdf = and ftp:/= /ftp.cls.fr/pub/ids/satellites/macromodels/spot3mod.pdf

* There was a typo on the diffuse reflectivity coefficients correspondin= g to the visible spectrum , the correct values are 0.07 (instead of 0.7)

* Angle between solar array and Xs axis:  the correct value is 17 deg (instead of 5 deg)

Spot5  ftp:/= /ftp.cls.fr/pub/ids/satellites/macromodels/spot5mod.pdf<= /span>

Update with the alignment operation of the solar panel in January 2008<= /span>

An angular bias on the orientation of the array on its rotation axis was added in 3 steps:

On Jan. 15: an angle of +25=B0 with respect to the origin posit= ion was applied

On Jan. 17: an 2nd additional angle of +10=B0 was applied<= /o:p>

On Jan. 22: a 3rd additional angle of +5=B0 was applied

 

Thus , the current angle is +40=B0 with respect to the origin position after Jan 22 2008

Envisat: ftp://f= tp.cls.fr/pub/ids/satellites/macromodels/en1mod.pdf

The axes convention have been added in the document (at the end), it is the same convention as for Spot:

 +Xs is along the satellite main direction (-Xs is pitch axis)

+Ys is transverse. -Ys =3D  velocity direction  (-Ys = is roll axis)

+Zs is radial pointing outwards the Earth, ( +Zs is yaw axis )
