Abstract

Disclosed is a system that provides drones with established dynamic three-dimensional (3D) geofences (space blocks) to aid in navigation. The system dynamically reserves air space for drone consumption and includes dynamic space booking capabilities, adjustment for environmental factors, allowance for variances in treatment based on drone size, and visualization path mapping for specific data points to drones and unmanned aerial vehicles (UAVs).

Dynamic Three-Dimensional Geofence Mapping for Drones

Drones fly freely, navigate the sky with limited constraints, and can easily collide while fulfilling assigned objectives and deliveries. This potential collision problem is expected to increase as drones concurrently fly within close proximity of one another. As drone traffic increases, the issues associated with crowded air space at lower altitudes within towns, city centers, and metropolitan areas can increase.

The lack of three-dimensional (3D) geofencing space within the sky creates the potential for drones to collide without any rules to follow or system to accommodate higher levels of drone traffic at present and in the future.

A method and system are needed to dynamically reserve air space for drone consumption, including dynamic space booking capabilities, adjustment for environmental factors, allowance for variances in treatment based on drone size, and visualization path mapping for specific data points to drones and unmanned aerial vehicles (UAVs).

The novel contribution to knowledge is a system that provides drones with established dynamic 3D geofences (space blocks) to aid in navigation. A central registration and reservation system manages the booking of blocks based on the physical attributes of the booking drones. The associated system adjusts the block reservations based on environmental conditions. The system has the ability to control and dynamically adjust the size of the geofencing area based on the size of the UAV/ drone. The speed of the drone can dynamically dictate the allocation of space required for the reservation system.

During implementation, drones reserve space blocks for a time when the drone expects to travel through that block. The size of the block is dependent on the drone’s physical characteristics. The system can dynamically designate blocks into units wherein a drone books a number of units dependent on its size. This booking system allows drones to travel safely through a shared space, minimizing the number of accidents. Note that the resulting flight path might not be linear, but zigzag across the flight area. The dynamic booking system also considers environmental conditions, as this. This is needed, for example, to ensure that the system can accordingly adjust the time value of the booking. For example, wind may cause a drone to fly slower than anticipated; therefore, the system needs to adjust the required booking per...
