Hello-
I wasn't sure how most people would like to see stuff posted. Or if this would interest many people. But in the interests of putting out more information, I created this topic as a place to put information on Venus Express science planning. If you have any ideas about this, let me know. Cheers- Don Merritt -------------------- --

Excellent updates Don, much appreciated.
This detail caught my eye QUOTE This is actually implemented onboard by commanding fake ephemeredes (i.e. with non-real S/C and Earth positions). By proper selection of the fake ephemeredes, the distortion of the Earth pointing guidance computation on-board achieves Earth pointing with the HGA and a tilt angle around the HGA axis. Is this an unusual approach to a problem like this? |
