HEX sUAS SYSTEM DESCRIPTION

sUAS Operating Overview : Prioria's Hex Flyer is a multi

- rotor, vertical take

- off and landing platform. It simplifies users’ installation and enables quick disassembling. Frame arm integrates with ESC and motor. With DJI WKM autopilot system, it can achieve hovering, cruising and other flig ht elements. Hex Flyer can be applied for aerial photography and other

aero

- modeling activities.

The basic airframe T810 is manufactured by Tarot

- RC , leading manufacturer of consumer and commercial grade unmanned aerial systems. The T810 airframe is used e xtensively in TV and film industry as an aerial video/photo platform. Prioria performs all assembly and payload integration.

The sUAS can be operated in fully autonomous flight modes. Creating pre

- planned flight paths to fly in autonomous mode is as simple as clicking on the map to create a pre

- planned flight path. Pre

- mission waypoints, landing zone points, and flight area dimensions can all be entered during preflight, ensuring the sUAS operates only within specified parameters.

Built

- in intelligent fault handling allows the sUAS to detect a system fault while in the air, and to automatically respond with a set command (one such opti on being to fly back to a pre

selected rally point and land )

. Faults that can be detected include: loss of communication, loss of GPS, and low battery levels.

Power

– The Hex and its ground control station are both power e d by a Lith ium polymer rechargeable battery pack. A new battery has a fully charged voltage of approximately 25.1 V.

The Hex ’s battery charge is displayed in real

- time on the ground control station , ensuring maximum flight duration and safety.

Launch and Recovery Procedures The Hex Flyer utilizes vertical takeoff and landing, commanded either via Radio Control Transmitter or Automatic operation via Data Link and Ground Station Software. In RC mode, Pilot uses GPS, Attitude, or Manual modes via RC hand controller to maneuver aircraft for takeoff or landing. To utilize automatic operation, Pilot sets GPS flight mode in RC Controller, then uploads flight plan to aircraft via Datalink. Once upload is complete, pressing "GO" button in GS activates auto takeoff and flight to first waypoint in flight plan. For landing, pilot sets Go Home mode in GS. Once Aircraft is situated over Home waypoint in stable hover, Pilot sets "Autoland" mode. Aircraft then executes slow descent automatic landing.

Takeoff and Landing style/type

– The Hex uses a vertical takeoff and landing style

, commanded either via Radio Control Transmitter or Automatic operation via Data Link and

Ground Station Software. R/C: Pilot uses GPS, Attitude, or Manual modes via RC hand

controller to maneuver aircraft for takeoff or landing.

Automatic: Pilot sets GPS flight mode in RC Controller, then uploads flight plan to aircraft via datalink. Once upload is complete, pressing "GO" button in GS activates auto takeoff and flight to first waypoint in flight plan. For landing, pilot sets Go Home mode in GS. Once Aircraft is situated over Home waypoint in stable hover, Pilot sets "Autoland" mode. Aircraft then executes slow descent automatic landing.

Navigation System

– GCS uses Google Earth Plugin for live map imagery which can also be

pre

- cached for offline use in the field. Waypoints can be created before and during flight operation creating specific locations and sequences for the aircraft.

Maintenance

– The Hex sUAS needs very little maintenance, and operators may perform most required maintenance in the f ield with the field repair kit

Command and Control Systems

- The Main Controller (MC) is the brain of the system

. I t communicates with the IMU, GPS/Compas s, ESC s, and RC transmitter to carry out autopilot

functi onality. The Main Controller has a USB interface for configuration and firmware updates via a PC. The Inert ial Measurement Unit (IMU) consists of one 3

- axis accelerometer,

one 3

- axis gyroscope and a barometer. It is used for sensing the attitude. The GPS/C ompass module is for sensing the position and direction. The LED indicates different states of system. Specially designed for the Controller to convert the higher voltage of the power circuit to the lower voltage required for the receiver etc. It contains two regulated power outputs for the

Prioria Robotics, Inc. Privileged and Confidentialentire Controller system and receiver separately, a battery voltage monitor, and C AN

- Bus

interfaces.

Ground Control Station

Ground Station enables 3

- D Map Way Points Editing, Flight Path Planning, Real

- time Flight

State Feedback and Auto Takeoff and Landing. Working with the autopilot system, DJI Ground Station not only ensures stable performance and safety of the aircraft, easy operation for the pilot, but also allows the aircraft to fly along the flight path set before or modified during the flight mission in the Ground Station software autonomously.

Emergency Procedures and System Failures

Loss of Link

– The sUAS does not need constant signal from the GCS to continue flying. Communications outages are det ected by the system and are reported to the PIC. During the communication outage, the sUAS continues on its pre

- determined flight path until a failsafe is triggered. Once a failsafe is triggered, the sUAS will perform in accordance with the failsafe cond itions uploaded before launch. This is accomplished without input from the operator.
