"I'm currently working with some pressure sensors for work. I've managed to extract a usable 1mm of water (about 0.01kPa) noise floor out of some Freescale absolute pressure sensors which read from -80 to +150kPa (gauge). That's about…"

Andrew Dunlop replied to Andrew Burns's discussion Ardupilot and Millswood Engineering GCS"Hi Peter,
That is good to hear. I had a quick look at the 2.6 source and it did appear that your telemetry data came from an earlier version. Having said that, there are a number of changes that 2.6 implements that my GCS does not handle. So when I…"
Peter Seddon replied to Andrew Burns's discussion Ardupilot and Millswood Engineering GCS"Andrew,
With the latest 2.6 APilot code the Millswood GCS seems to work correctly - I haven't done a very detailed check but it did cure one of my major problems and the AI now works.
regards Peter"
Peter Seddon replied to Andrew Burns's discussion Ardupilot and Millswood Engineering GCS"Andrew,
I have been struggling to get automatik's GCS to work as well due to telemetry changes in the code. He has recommended I try the latest version of the 2.6 code which maybe closer to the version you used as well. I am about to do so I…"
Andrew Dunlop replied to Andrew Burns's discussion Ardupilot and Millswood Engineering GCS"Ah, I see. Thanks Peter.
Ardupilot telemetry has been significantly enhanced since I wrote the GCS. It doesn't look to difficult to include the new stuff; I'll get onto it once a few other jobs are squared away.
Cheers,
Andrew"
Peter Seddon replied to Andrew Burns's discussion Ardupilot and Millswood Engineering GCS"Sorry for the very long delay.
Here is a file of some data that has come out of my AP.
regards Peter"
Andrew Dunlop replied to Andrew Burns's discussion Ardupilot and Millswood Engineering GCS"Hi Peter,
Have you had any luck getting the GCS to work?
If you are able to save the incoming data to a file it would be instructive to take a look at it.
Cheers,
Andrew"
Peter Seddon replied to Andrew Burns's discussion Ardupilot and Millswood Engineering GCS"I wonder if others have had any problem using this?
I am using Ardupilot 2.6 and a Dell Win 7 laptop.
Here are my problems when on the ground:
1. The heading indicator (artifical horizon) does not respond even to my hand in fornt of the…"

Andrew Burns commented on Chris Anderson's blog post ArduPilot Mega Now Available!"Significantly larger main microcontroller, significantly larger failsafe controller, larger boards which will cost more, many more tracks which would have required a lot more effort to route etc... It's still fairly cheap when you consider the…"
Andrew Burns commented on Chris Anderson's blog post ArduPilot Mega Now Available!"Any news on code? This would be the ultimate low-cost autopilot for the Outback UAV challenge I think assuming the ground control software has a few key features (waypoint upload and real-time gain changing/plotting I would list as the most useful)."
Andrew Burns commented on Chris Anderson's blog post What our cousins in rocketry are doing"Another rocket 'flight computer' being developed by a friend can be found here: http://ausrocketry.com/forum/viewtopic.php?f=32&t=1922

Andrew Burns commented on Jordi Muñoz's blog post ArduPilot Mega Updates, updates!"So there's no differential pressure sensor, this means everything is calculated based on GPS ground speed? How then can the aircraft manage throttle to maintain constant airspeed? And if you don't manage airspeed your gains will always be…"

"Well until you go out to some fair distances a good Omni directional ant is ok.
Its all extra rubbish to pack when you go flying!"
Morli replied to Andrew Burns's discussion Ardupilot and Millswood Engineering GCS"@Gary,
:) , Yep you told earlier 500/1000 M VLOS but "Mobile GCS are forbidden in most places" , I didn't know that :((,
thanks for the info . So do you think ant tracking is good thing to have in GCS or not ?"
ModeratorGary Mortimer replied to Andrew Burns's discussion Ardupilot and Millswood Engineering GCS
"VLOS has been defined as 500m by ICAO Morli, flight to 5km would be BLOS.
In South Africa we are allowed out to 1km VLOS, UK 500m both not above 400'
Mobile GCS are forbidden in most places. As are multi ground stations, the next…"
