YES2 Post Flight Analysis v2

A public version of the post flight data analysis is now available, see attachment. It does not yet include the GPS and accelerometer data. Analysis of this data could lead to a significant improvement of the estimate of Fotino's fate and potential landing site. Also we are currently analyzing the exact cause of the failure of the OLD signal registration in the second stage (*).

(*) It was so far demonstrated that the problem was present in the flight model at time of delivery, but NOT in the engineering model, so it is probably related to an electronical patch that was installed shortly before delivery on the flight model only and tested due to time constraints only till 4 m/s compared to the max. velocity of 13 m/s in YES2 flight. Ilias has performed some breadboard testing suggesting that thermal (heating) effects related to this patch may be to blame, but this is yet unconfirmed. IMTsrl is testing the electrical interface on the OBC board. A test will yet be performed at Delta-Utec to make demonstrate the software was indeed able to deal with the velocity (as it was in the engineering model) so that the problem can be narrowed down to the electrical interface hardware.
