Debugging

Introduction

It is critical to verify the safety and correctness of mission plans in order to avoid property damage, injury, and wasted effort. Dronelink provides virtual and physical debugging tools to make debugging safe, effective, and efficient.

Mission Previewer virtual

The mission previewer displays a millisecond-accurate, simulated mission right in your browser. The simulation is generated using the same flight code that runs during real missions in the native app, which guarantees identical results. Results are typically available within seconds and include an overview window, 2D and 3D flight path previews, and a timeline window. The timeline shows components, commands, and graphs for altitude, distance (from takeoff), horizontal speed, and vertical speed. The timeline also allows auto-playback (at real-time, 2x, 4x) and manual scrubbing, which are synchronized with the overview window and flight path previews.

We recommend opening the mission previewer early and often during mission planning to avoid rework. At a minimum, you should open the mission previewer once before flying a mission in the real world.

Issue Detector virtual

The issue detector is an automated, background process that constantly checks mission plans and components for potential issues while editing. The detector displays correction recommendations for each issue, and includes a link to the corresponding component for easy access.

Verification Missions physical

It is possible to fly a verification mission for any plan by tapping ... > Load Verification Mission in the native app. Dronelink will generate a new mission with the drone pointed forward along the flight path, which allows the onboard sense-and-avoid hardware to operate correctly. If the drone is able to successfully execute the verification mission in this configuration, you are guaranteed of no collisions during the real mission.

IMPORTANT: Your drone must have onboard sense-and-avoid hardware for this feature to function properly.
