PRATCHETT chats to Oz from 31,000m above Planet Earth

Andrew Tridgell tunes into LOHAN avionics test flight

Other sensors

Other data grabbed by the Pixhawk includes the mission pitch-roll. Not very significant with regard to the Vulture 2, but a good indication of just what a battering the PRATCHETT payload took.

Tridge explained:

Here's overall roll-pitch graph against altitude (degrees of roll/pitch, altitude in meters above sea level):

The PRATCHETT pitch and roll graph

Here is a zoom into part of the ascent, you can see a typical 20 degree swing, with occasional 50 degree swing. The frequency of the oscillation is between 1 and 2Hz:

Here it is at burst:

Quite a ride. In summary then, we've got a few things to fix, but nothing that's going to give us sleepless nights. We offer the traditional thanks and foaming ales to Tridge and all the Edge team for their magnificent efforts. Onwards and upwards...®


It's also foaming ales and (belated) congratulations to Edge members Emily and Jeremy Allen... Emily and Jeremy Allen
