Hi everybody

Paparazzi's microjet won the JMD04 MAV event ( )

During the event, we had contact with industrials who told us they were
interested in manufacturing our board. Maybe the end of the nightmare for those
of you who don't enjoy soldering iron :)

We've received PCBs and assembled the new version of the controller board
(v1.2.1) - The servo driver reset bug is fixed and the board seems to behave
well on the desk - We'll let you  know how it does in flight in the following

We've tagged the version that we used for the trophy (jmd-04 ). You should be
able to safely upgrade from the previous tagged version (emav-04). Most
noticable difference is the use of UTM in place of GWS84. You'll have to setup
your GPS receiver to output the correct messages. Maybe we could add our
receiver configuration in the CVS ?

You will also need a patched version of ivy (the network software bus)
while the guy at make a new release with the patches we sent them.

We're setting up a debian package repository and let you know when it's done.

We intend to break everything in the CVS head in the following days to add
groung station support for several aircraft at once, so you'd better stick to
the jmd-04 version for now.

During the flight competition, we once again had trouble with radio jamming. We
really need a checksumed rf transmission. I will call Multiplex once more to
ask for their PCM specifications. If they refuse once again to disclose it, I
want to define and implement a new "open" PCM protocol, eventually with low
throughput data in it. We could use a commercial HF module (maybe even a
frequency synthesys once) and connect it to the laptop. Then fly using a
joystick or a simulator transmitter.

Do you have idea about a suitable protocol or know the interface of a commercial
HF module ?
