Abstract
The present disclosure relates to a system and method for executing safe-return of an Unmanned Aerial Vehicle (UAV) moving along a path having a plurality of communication waypoints in the event of a communication failure. In an aspect, the proposed method can include the steps of detecting, at the UAV, a communication failure; enabling the UAV to return to last healthy communication waypoint location; and based on status of the communication failure, enabling the UAV to return to its home location.
Claims10
A method for emergency path planning for an Unmanned Aerial Vehicle (UAV) in an event of communication failure on account of an obstacle, said UAV moving along a path having a plurality of communication waypoints, each communication waypoint providing communication between the UAV and a home location through a wireless radio link, the method comprising the steps of:
- detecting, by a flight control system of the UAV, a communication failure resulting from loss of wireless radio link communication;
- enabling, by the flight control system, on detection of the communication failure, the UAV to return to a last healthy communication waypoint location, the last healthy communication waypoint location being a communication waypoint out of the plurality of communication waypoints with healthy signal and selected based on one or more factors selected from the group of on-board sensor status/condition and nominal mission parameters comprising total time, total distance, distance travelled, payload weight, payload condition/health;
- and
- waiting, at the last healthy communication waypoint location, by the flight control system, for a defined time period for communication to return before enabling the UAV to return to its home location.
A system configured for emergency path planning fora UAV in an event of communication failure on account of an obstacle, said UAV moving along a path having a plurality of communication waypoints, each communication waypoint providing communication between the UAV and a home location through a wireless radio link, said system comprising:
- a communication module;
- a flight control system operatively coupled with the communication module so as to detect a communication failure and, based on such detection, return the UAV to a last healthy communication waypoint location, the last healthy communication waypoint location being a communication waypoint out of the plurality of communication waypoints with healthy signal and selected based on one or more factors selected from the group of on-board sensor status/condition and nominal mission parameters comprising total time, total distance, distance travelled, payload weight, payload condition/health, wherein the flight control system is configured to wait for a defined time period before enabling the UAV to return to its home location, the detected communication failure resulting from loss of wireless radio link communication.
