You are correct, this satellite was launched to the south. The LAUNCH
AZIMUTH was 192.0000 DEG.
The orbital element I had posted was for when the satellite was to pass
over africa, the time of separation from the OAM - ORBITAL ADJUST MODULE.
Of course It doesn't matter since the satellite was lost. 
There is always ikonos 2. 
There is one other 1 meter resolution satellite to be launched this year. 

"Nov. 19: Orbital Sciences Pegasus XL with OrbView-3 Earth imaging
satellite staged from Vandenberg Air Force Base, Calif. Launch Time TBD."

So it will still be possible to get high resolution sat photo's.

Now I wonder where that new milstar will be going. I read somewhere it is
going to replace one of the milstar's in orbit. Are will it be in a
different orbital slot.
