In recent years, smart agriculture using ICT, IoT, and robotics technology has been attracting attention. In our related works, the pear pollination works technology using drones has being developed. The drones flies in pear fields, finds flowers for pollination, and then sprays pollen with high precision. In order to achieve these tasks, drone flight accuracy by positioning is required. Conventional outdoor drones fly using global navigation satellite system (GNSS), which receives signals from satellites and estimates their own position.
However, conventional positioning methods have an error of several meters to tens meters from indicated route. When flying the drones in the pear field, since it needs to fly through narrow spaces between trees with an accuracy into tens centimeters or less, flight control is very difficult. Therefore, in our study, in addition to GNSS position information, real time kinematic (RTK), which performs positioning correction at the ground station, is used to achieve positioning within a few centimeters in the pear field. In this paper, we explain the principle of positioning, and report on the development of a positioning system using RTK and the flight experiment of a drone. |
