I can comment that we're making advances in signal processing technology that goes on board, so you can actually get maybe better resolution, more data, better pictures of ships and so on, and better determination of the scene you're looking at.
There have been advancements, but it's not the only technology in the world. Europeans have many SAR radar satellites. We believe we are competitive on the world scale on that, but I would say that over time many hundred millions of dollars have been invested in that technology.
