If you have Save telemetry log after each flight turned on you will no longer be prompted as to where to save the log each time the vehicle disarms. If this setting is turned on, QGroundControl will automatically upload a plan to the vehicle when it connects. The plan file must be named AutoLoad.

You can now specify a save path which QGC will use as the default location to save files such as Parameters, Telemetry or Mission Plans. Previous version of QGroundControl saved missions, geo-fences and rally points in separate files.

QGC now save all information related to a flight plan into a single file called a Plan File with a file extension of. The new Plan Toolbar is displayed at the top of the PlanView.

It shows you information related to the currently selected waypoint as well as statistics for the entire mission. When connected to a vehicle it also shows an Upload button, which can be used to upload the plan to the vehicle.

The Mission Settings panel allows you to specify values which apply to the entire mission, or settings you want to control right at the beginning of a mission. This is the first item in the mission list on the right of the screen. This specifies the default altitude for newly added mission items.

If you update this value while you have a mission loaded it will prompt you to update all the the waypoints to this new altitude. This allows you to set the flight speed for the mission to be different than the default mission speed.

The camera section allows you to specify a camera action to take, control the gimbal and set your camera into photo or video mode.

When planning a mission the firmware being run on the vehicle as well as the vehicle type must be known in order for QGroundControl to show you the mission commands which are appropriate for your vehicle.

If you are planning a mission while you are connected to your vehicle the Firmware and Vehicle Type will be determined from the vehicle.

If you are planning a mission while not connected to a vehicle you will need to specify this information yourself. The additional value that can be specified when planning a mission is the vehicle flight speed.GitHub is home to over 40 million developers working together to host and review code, manage projects, and build software together.

I have a 3 axis gimbal that's operated by a second TX providing ppm into the main radio and mixing etc and the gimbal is capable of emitting a mavlink heartbeat but I've not yet got this connected up in such a way that I've been able to see the mavlink data from it in qgroundcontrol.

The gimbal setup tool has a cool little widget that allows you to recentre any axis or the whole gimbal, and it has positions like 'look down' and 'look forwards'. This nicely compliments the relative positioning control of the gimbal we have via the 2nd tx if it is possible I'd probably go for this option if it would work Gimbal control is now more easily support in missions daily build but still not gimbal controls to use while just flying manually.

So at this moment there is no way to control a Mavlink Storm32 gimbal thru manual controls on the radio transmitter? I try to search a step by step instructions to setup the serial port for controlling the Storm32 but with no success.

This all works just fine using the pots on my transmitter which are mapped to channels 10, 11, and 12but I would like to be able to control the gimbal using mavlink commands set from mavproxy 1.

I thought this seemed like the obvious solution for trying to control, for example, the gimbal tilt…. In all cases, I get the following response:. Are you using the mount feature? I can control the gimbal fine with the RC. Under the action tab I select MAVlink target from the drop down and hit set mount.

QGroundControl v3.2 Release Notes (Detailed)

Am I missing some other step. It differs in the way it is handled inside ArduPilot. The gimbal module sends a command that is executed immediately without the need to save it.

Thanks for the timely reply. Just looked at mission planner. It looks like do-digicam-control sets the parameters of the camera, which is not what I need.

I am trying to command the actual gimbal to move during an auto mission. Yeah, me neither. Sorry for not being clear. What I meant is that there might be a bug in the way we handle these commands when used in a mission.

If you have a log where you try to use the servo command it may be possible to see if the output value changed or not.

Also, if you are using the mount settings, you need to change the mode to MAVLink targeting you can do that with the gimbal module too. Maybe test the module first to see if it does what you expect or not. Well, I have at least solved the mystery of why the servo set If I reset the corresponding parameters to 0I am able to control the gimbal with servo set as expected.

If you set the respective RCx to zero will it still work with the remote control? I want to control the gimbal with the RC on non auto mission and mission planner ti command it to the set parameters when flying auto missions. When your mission is complete you will once again have manual control.

Use the mount control commands is in some ways a little less convenient that being able to set a single servo output to a particular value, but it ends up being more flexible.

Thanks for the reply. The method you described is how I currently have my gimbal set up. I missed the mavlink targeting action the first few times I tried it but eventually figured that one out. When the mission is over, the mount mode returns to RC targeting and I can once again use the transmitter to control the gimbal.

Thanks for posting the details of your set up. Mine is similar. I saw in another post you use qControl as your GCS so the gimbal set up may be different from mission planner. I am using servo and wondering if I need to use Alexmos serial to get it to work via mavlink on auto missions.

Tomorrow, I will continue to debug the code to find the real reason. Controlling camera servos via mavlink commands? Is this a problem with my APM configuration? Or am I just not doing this the right way?QGroundControl is an app to configure and fly a PX4 based autopilot.

It is cross platform and supports all major operating systems:. A context menu will open on the side to adjust the waypoints. Click on the highlight transmission icon to send them to the vehicle. Switch to the flying tab.

The mission should be visible on the map. If the vehicle is already in flight it will fly to the first leg of the mission and then follow it. Switch to the setup tab. Scroll the menu on the left all the way to the bottom and click on the parameter icon. Parameters can be changed by double-clicking on them, which opens a context menu to edit, along with a more detailed description.

It is also use to configure the GeoFence and Rally Points if these are supported by the firmware. The screenshot above shows a simple mission plan that starts with a takeoff at the Planned Home position Hflies through three waypoints, and then lands on the last waypoint i. It shows you information related to the currently selected waypoint as well as statistics for the entire mission.

The Planned Home shown in Plan View is used to set the approximate start point when planning a mission i. It is used by QGC to estimate mission times and to draw waypoint lines. The altitude for the planned home position is set in the Mission Settings panel. The main tools are described below.

While active, clicking on the map will add new mission waypoint at the clicked location. The tool will stay active until you select it again. Once you have added a waypoint, you can select it and drag it around to change its position. The tool displays an!

The Pattern tool simplifies the creation of missions for flying complex geometries, including surveys and structure scans. Mission commands for the current mission are listed on the right side of the view. At the top are a set of options to switch between editing the mission, GeoFence and rally points. Within the list you can select individual mission items to edit their values.

You can change the type of the command by clicking on the command name for example: Waypoint. This will display the Select Mission Command dialog shown below. By default this just displays the "Basic Commands", but you can use the Category drop down menu to display more e. To the right of each command name is a menu that you can click to access to additional options such as Insert and Delete. The list of available commands will depend on firmware and vehicle type.

Examples may include: Waypoint, Start image capture, Jump to item to repeat mission and other commands. The Mission Start panel is the first item that appears in the mission command list.

It may be used to specify a number default settings that may affect the start or end of the mission. Set the default altitude for the first mission item added to a plan subsequent items take an initial altitude from the previous item. This can also be used to change the altitude of all items in a plan to the same value; you will be prompted if you change the value when there are items in a plan.

The Planned Home Position section allows you to simulate the vehicle's home position while planning a mission.

Setup View

This allows you to view the waypoint trajectory for your vehicle from takeoff to mission completion. This is only the planned home position and you should place it where you plan to start the vehicle from. It has no actual impact on flying the mission. The actual home position of a vehicle is set by the vehicle itself when arming.

The section allows you to set the Altitude and Set Home to Map Centre you can move it to another position by dragging it on the map.The diagrams use the standard PX4 notation and each have an annotated legend. The code is implemented as a library which is used in the fixed wing position control module.

As seen in the diagram above, TECS receives as inputs airspeed and altitude setpoints and outputs a throttle and pitch angle setpoint. These two outputs are sent to the fixed wing attitude controller which implements the attitude control solution. It's therefore important to understand that the performance of TECS is directly affected by the performance of the pitch control loop. A poor tracking of airspeed and altitude is often caused by a poor tracking of the aircraft pitch angle.

Simultaneous control of true airspeed and height is not a trivial task.

Codeigniter libraries

Increasing aircraft pitch angle will cause an increase in height but also a decrease in airspeed. Increasing the throttle will increase airspeed but also height will increase due to the increase in lift.

Therefore, we have two inputs pitch angle and throttle which both affect the two outputs airspeed and altitude which makes the control problem challenging. TECS offers a solution by respresenting the problem in terms of energies rather than the original setpoints. The total energy of an aircraft is the sum of kinetic and potential energy. Thrust via throttle control increases the total energy state of the aircraft. A given total energy state can be achieved by arbitrary combinations of potential and kinetic energies.

In other words, flying at a high altitude but at a slow speed can be equivalent to flying at a low altitude but at a faster airspeed in a total energy sense.

PixHawk Masterclass: Camera triggering and mission planning

We refer to this as the specific energy balance and it is calculated from the current altitude and true airspeed setpoint. The specific energy balance is controlled via the aircraft pitch angle. An increase in pitch angle transfers kinetic to potential energy and a negative pitch angle vice versa.

The control problem was therefore decoupled by transforming the initial setpoints into energy quantities which can be controlled independently.

qgroundcontrol gimbal control

We use thrust to regulate the specific total energy of the vehicle and pitch maintain a specific balance between potential height and kinetic speed energy. In level flight, initial thrust is trimmed against the drag and a change in thrust results thus in:.

As can be seen, is proportional toand thus the thrust setpoint should be used for total energy control. Elevator control on the other hand is energy conservative, and is thus used for exchanging potentional energy for kinetic energy and vice versa.

To this end, a specific energy balance rate is defined as. The attitude controller works using a cascaded loop method. The outer loop computes the error between the attitude setpoint and the estimated attitude that, multiplied by a gain P controllergenerates a rate setpoint.

The angular position of the control effectors ailerons, elevators, rudders, Furthermore, since the control surfaces are more effective at high speed and less effective at low speed, the controller - tuned for cruise speed - is scaled using the airspeed measurements if such a sensor is used.

The feedforward gain is used to compensate for aerodynamic damping. Basically, the two main components of body-axis moments on an aircraft are produced by the control surfaces ailerons, elevators, rudders, - producing the motion and the aerodynamic damping proportional to the body rates - counteracting the motion.

In order to keep a constant rate, this damping can be compensated using feedforward in the rate loop. The roll and pitch controllers have the same structure and the longitudinal and lateral dynamics are assumed to be uncoupled enough to work independently. The yaw controller, however, generates its yaw rate setpoint using the turn coordination constraint in order to minimize lateral acceleration, generated when the aircraft is slipping.

The objective of this section is to explain with the help of equations why and how the output of the rate PI and feedforward FF controllers can be scaled with airspeed to improve the control performance. We will first present the simplified linear dimensional moment equation on the roll axis, then show the influence of airspeed on the direct moment generation and finally, the influence of airspeed during a constant roll.
