Quick Start

Introduction

The section will take you through an example of planning a new mission and running it. The mission we define for this purpose is a circular mission taking oblique images, starting with general and quick one-time settings, and going thought the three steps of planning, executing, and offloading images. The drone that we use to complete the mission is the DJI Phantom 4 Pro.

Executing the Mission

Before you go to the field to execute the plan, please check the following:

  1. Make sure all batteries for the drone, the remote control, and the tablet are fully charged.
  2. Make sure that your drone is calibrated using the DJI Go application. If the drone is not calibrated, DatuFly will display an appropriate message.
  3. Make sure you have enough free space on the drone’s micro SD card.
  4. Select a takeoff location that is approximately at the same level as the area to be photographed.

Once you go to the area you want to photograph, follow the steps below to execute the planned mission.

  1. Stand in an area with considerable open space and no obstructions above you.
  2. Start the DatuFly application.
  3. Select the appropriate mission to be executed.
  4. If needed you can make last minute changes in the field based on the terrain.
  5. Tap Update Flight Plan.
  6. Start the drone’s remote control, and wait a few seconds to make sure it is functioning.
  7. Start the drone and place it in an open area.
  8. Tap Connect Drone. Several messages are displayed informing you that various functions are being checked. If any of the functions fail, DatuFly will notify you and will provide suggestions about how to rectify the situation.

  9. Once all functions are working properly, the “Safe flight foreseen” notice is displayed (Figure 15).

    The drone will take off and fly to the first point in the circle and starts circulating around the points of interest taking images. Note in Figure 18 that the icon indicating the nose of the drone points to the center of the circle.
