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.

tapes or disks of sensor data
PLANNING OPERATION

7. OPERATOR’S WORKSTATION

8. GROUND STATION SETUP

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
