[Space Intel Report] Interview: ViaSat President and COO Richard A. Baldridge

Q: How long until ViaSat-2 gets to final GEO position?

A: We finished the chemical part of the orbit raising and the current assessment is October arrival on station. Our co-passenger [Eutelsat’s all-electric 172B] wasn’t determined initially, and turned out to have greater mass than most. A lighter co-passenger would have allowed more chemical propellant and a shorter overall orbit raising time. But we’re still happy with the trade-off, given that we’ll have the use of the payload capability for far longer than the difference in the orbit raising time.
