Mission planning and control for UAV's

This document summarizes the functions and components of a Mission Planning and Control System (MPCS) for unmanned aerial vehicles (UAVs). The MPCS controls launch, flight and recovery of the UAV. It processes sensor data and controls the payload. Key components include displays for vehicle and payload status, map displays for mission planning, a data link for communication, and computers for interface, navigation and calculations. The MPCS allows operators to plan missions, monitor the UAV's position, control the vehicle and payload, and save sensor data. Modes of control include full remote control, assisted remote control, exception control, and full automation. The document also discusses controlling payloads and missions.
Mission planning and control for UAV's
- 1. UNIT-5 MISSION PLANNING AND CONTROL Suthan R Asst Professor Department of Aeronautical Engg NMIT-Bangalore
- 2. FUNCTIONS MPCS, is the “nerve center” of the entire UAV system. It controls the launch, flight, and recovery of the air vehicle (AV) Receives and processes data from the internal sensors of the flight systems and the external sensors of the payload; Controls the operation of the payload (often in real time); and Provides the interfaces between the UAV system and the outside world
- 3. SUBSYSTEMS AV status readouts and controls. Payload data displays and controls. Map displays for mission planning and for monitoring the location and flight path of the AV. The ground terminal of a data link that transmits commands to the AV and payload and receives status information and payload data from the AV. One or more computers that, at a minimum, provide an interface between the operator(s) and the AV and control the data link and data flow between the AV and the MPCS. They may also perform the navigation function for the system, and some of the “outer loop” (less time sensitive) calculations associated with the autopilot and payload control functions. Communications links to other organizations for command and control and for dissemination of information gathered by the UAV.
- 6. MPCS Process tasking messages Study mission area maps Designate flight routes (waypoints, speeds, altitudes) Provide operator with plan Load mission plan information Launch UAV Monitor UAV position Control UAV Control and monitor mission payload Recommend changes to flight plan Provide information to the commander Save sensor information when required Recover UAV Reproduce hard copy or digital tapes or disks of sensor data PLANNING OPERATION
- 9. AIR VEHICLE AND PAYLOAD CONTROL The remote operators, usually assisted by computers located both on the ground and in the AV, must perform the functions of the aircraft commander, pilot, copilot, radar and/or weapons operator, and any other functions that would be performed by humans onboard for a manned system.
- 10. FUNCTIONS Piloting the aircraft: making the inputs to the control surfaces and propulsion system required to take off, fly some specified flight path, and land. Controlling the payloads: turning them on and off, pointing them as needed, and performing any real- time interpretation of their outputs that is required to perform the mission of the UAS. Commanding the aircraft: carrying out the mission plan, including any changes that must be made in response to events that occur during the mission. Mission planning: determining the plan for the mission based on the tasking that comes from the “customer” for whom the UAS is flying the mission.
- 11. MODES OF CONTROL Full remote control: the humans do all the things that they would do if they were onboard the AV, basing their actions on sensor and other flight instrument information that is downlinked to the operator station and implemented by direct control inputs that are uplinked to the AV. Assisted remote control: the humans still do all the things that they would do if they were on the AV, based on the same information downlinked to them, but their control inputs are assisted by automated inner control loops that are closed onboard the AV. Exception control: the computers perform all the real-time control functions based on a detailed flight plan and/or mission plan and monitor what is happening in order to identify any event that constitutes an exception to the plan. If an exception is identified, the computers notify the human operators and ask for directions about how to respond to the exception. Full automation: the only function of the humans is to prepare a mission plan that the UAS performs without human intervention.
- 12. CONTROLLING PAYLOADS Signal relay or intercept payloads Atmospheric, radiological, and environmental monitoring Imaging pseudo-imaging payloads
- 13. CONTROLLING THE MISSION Loss of the command uplink of the data link Loss of GPS navigation (if used) Payload malfunctions Weather changes Change in flight characteristics (possibly due to structural damage) Something that has been observed with the sensor payload that triggers a task that has a higher priority than the preplanned mission
