Mission

Four steps

  1. 1

    Map the boundary

    Walk or fly the field edge once. The software stores it.

  2. 2

    Plan the route

    The software lays out passes, swath and height.

  3. 3

    Fly and spray

    The drone flies itself; flow is metered to ±2 %.

  4. 4

    Review the maps

    Coverage and crop-health maps after each job.
