"All the documentation is at http://canberrauav.readthedocs.io/en/latest/. Note the documentation is all quite old now, so may not be useful!"

Stephen Dade replied to Najam ul saiqb's discussion mavproxy module
"Take a look at http://ardupilot.github.io/MAVProxy/html/development/mavcustmod.html for an example of a MAVProxy module. Note the "init" function must return an instance of the module. For example "return ModuleName(mpstate)".…"

Stephen Dade replied to Eddi Maevski's discussion Arducopter 3.1.5 on APM 2.5 FC (clone) - missing parameters
"I think the Autotune_axes were added in after version 3.2.1 The wiki covers the latest version of Arducopter (3.4.4), so if you're using an older version the documentation will noty be accurate."

Stephen Dade replied to Ilya's discussion Connection APM2.6 to Raspberry Pi 3 with Mavproxy
"It's a bug in MAVProxy - you can't load waypoints via the --cmd="wp load mission.txt". There's a bug report at https://github.com/ArduPilot/MAVProxy/issues/142"

Stephen Dade replied to Nithin S's discussion About running python script in mavproxy
"Mission Planner (like all GCS's) sends heartbeat messages to the UAV. Not sure if there's a way to disable it. Why do you require Mission Planner between the UAV and MAVProxy? MAVProxy can talk directly to the UAV. I had a quick look at…"

Stephen Dade replied to Nithin S's discussion About running python script in mavproxy
"You can use events in Python to run a specific function when data is received over serial or UDP, instead of checking continuously. It's more complex to build this way though. You can get MAVProxy to automatically load your module on startup by…"

Stephen Dade replied to Nithin S's discussion About running python script in mavproxy
"That is definitely possible. You will need to write a MAVProxy module to do so. I recommend starting with a copy of the serial module (linked in my previous reply) and editing it from there. There's some documentation on developing MAVProxy…"

Stephen Dade replied to Nithin S's discussion About running python script in mavproxy
"The best way would be to create a MAVProxy module, based on the serial module (https://github.com/ArduPilot/MAVProxy/blob/master/MAVProxy/modules/mavproxy_serial.py)."

Stephen Dade replied to Tamir Y's discussion The purpose of MAVLink
"The site http://qgroundcontrol.org/mavlink/start has a list of flight controllers that use mavlink. Yes, you should be able to mix different flight controllers with different ground stations. One note though, some flight controllers have a few…"

Stephen Dade replied to Kasyap M's discussion GCS-UAV heartbeat requirement
"The wiki has undergone significant changes in the last 4 years! Hence the changed link. Try: http://ardupilot.org/copter/docs/gcs-failsafe.html http://ardupilot.org/copter/docs/failsafe-battery.html"

Stephen Dade commented on Mark Omo's group Outback Challenge
"We're all good for our D3 hours. Currently sorting out our final comms payload and ground station. 5 mavlink streams per UAV is a good level of redundancy!"

Stephen Dade replied to James Pike's discussion Mavproxy cmd_rc actually blocks rc commands - how should this be used
"That is expected behaviour. Use self.module('rc').cmd_rc([3, 0]) to reinstate the RC access to the channel. See the documentation at http://dronecode.github.io/MAVProxy/html/uav_configuration/system.html#rc"

Stephen Dade replied to Thomasss's discussion GPS position updates in Loiter mode
"Switching from stabilize to loiter the APM will query the GPS library for it's current position. The GPS library will return the position stored in it's memory. That current position will be between 0 to 20ms old. The APM won't…"
Jul 25, 2016
Stephen Dade replied to Thomasss's discussion GPS position updates in Loiter mode
"For the APM software, the general architecture is that the different sensor collection and position/orientation functions are in separate libraries (Object Orientated and all that...) and their state is read by the high level navigation…"

Cobham have recently released their "Aviator 200 UAV" - a satellite datalink system specifically made for small UAV's.

Although you'll likely need deep pockets to afford one, it shows that the satellite communications industry has realised there is a market for small UAV's that require…

Pixhawk (and APM) Power Consumption

Posted on September 10, 2015 at 5:10am 10 Comments

For most people running electric vehicles, it has always been assumed that the motor(s) will always use far more power than the flight controller and associated control systems.

However, for those people running internal combustion engines (or gliders, balloons, etc) for long duration flights the…
