Flight Mission Execution - Roof Mapping

In this guide we will walk you through executing a roof-mapping flight mission using the Hammer Missions platform. We will cover what to look for on the app, how to prepare and upload a mission, what to monitor / check and options available to you during the flight.

Quick overview: what you will see on screen

When you open the Hammer Missions app on your tablet or RC device you’ll see live telemetry information and camera feed. Key items to check are:

• Correct Drone model connection acknowledgement.
• Number of GPS satellites >11.
• Horizontal distance from home point.
• Live camera feed is working.
• Displayed map area is correct.

Before take-off: review mission parameters and telemetry

Always open the mission parameters (via the cog icon) and review/adjust the drone settings to confirm mission parameters. Typical items to verify:

• Maximum flight distance and maximum altitude for the operation.
• Obstacle handling behaviour and Return-to-Home (RTH) settings including RTH height.
• Correct Camera model, gimbal settings, Image storage destination and you also have the option for manual exposure adjustment, using the on-screen controls.

We recommend that you make any changes now, rather than when the drone is in the air. When you are happy, click the blue Done icon (top right) to return to main flight screen.

Pre-flight checks and uploading the mission

To begin, position the drone at a suitable take-off location and launch Hammer's pre-flight checks, by using the white triangle in the right side green panel. The system will run checks to ensure GPS lock, battery health and other critical parameters are OK.

Once the checks are complete (all items green status), ensure that the flight area is safe and press the Fly button to launch the drone. The mission uploads to the drone and the aircraft will automatically take off and climb to the mission altitude you set. If at any time you need to pause or abort the mission, you can use the pause button on your RC device or use the Red Circle with a square Red dot inside on the Hammer App.

Mission execution: follow the flight and camera operations

When the drone reaches its mission height, it will transition to the start of the mapping grid. The app displays the planned flight path:

• Planned segments start as yellow; once a segment is completed it changes to green, this acts as a simple visual confirmation each pass has been captured.
• A blue arrow icon shows the drone's real-time position as it executes the mission.
• The camera will adjust to the programmed angle and you will hear an audible click as it captures each photo.

Mid-flight control: pause, resume or return home

You’re never locked out once the mission is running — use the controls on the remote or the app to intervene:

• Pause the mission with the pause button on the RC or the red pause icon on the app. Pausing lets you assess or resolve an issue.
• After pausing you can choose to return home, resume the mission (press the play triangle), or perform other actions as required.
• During the mission, monitor the telemetry information: satellite count, altitude, horizontal distance and velocity. Any DJI-generated cautions (wind, sensor issues) appear in the top-left area of the screen or via the orange caution button.

Return and landing

When the mission completes, the drone will automatically return to the original take-off point and descend. For safety reasons, as it reaches the last few feet above the landing point, the drone will pause (in a hover) and you should manually confirm the landing area is clear, then apply "throttle down" input, to finalise the landing sequence.

Field tips and best practices

• Ensure that you have a safe flight area (on the ground and along the flight path) before commencing the flight.
• Double-check RTH altitude so the drone clears nearby obstacles on its return path.
• Use the camera exposure controls as necessary if you feel the auto exposure settings are not optimal.
• Monitor the colour changes on the flight plan (yellow → green) to verify capture coverage as the mission runs.
• Always be ready to pause and take manual control if environmental or operational conditions change.

Conclusion

Executing a flight mission with the Hammer Missions platform is very straightforward. Just follow our workflow, verify flight mission parameters and settings, run pre-flight checks, upload the mission, monitor the flight and camera, use pause/resume or RTH if required. With these steps in mind, you can capture reliable, complete datasets for roof inspections and mapping.
