Something was shaking the accelerometer pretty hard at 40 Hz. Very unlikely it was on the whole vehicle. We'll take Henry's and Doug's suggestions and see what NASA has to say about sensor isolation.

We don't know any of that yet. What number we give it will depend on how much we change. If enough of the proposed KISS IV mods make it into the next flight test, we'll probably just go ahead and call it KISS IV. Otherwise, KISS III.I, IIIa, IIIb, III.5? Who knows. We're not much interested in names at the moment. -R -- [EMAIL PROTECTED] "The only time an aircraft has too much fuel on board is when it is on fire." -Sir Charles Kingsford Smith _______________________________________________ ERPS-list mailing list [EMAIL PROTECTED] http://lists.erps.org/mailman/listinfo/erps-list
