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 flight 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 extensively 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 option being to fly back to a preselected rally point and land). Faults that can be detected include: loss of communication, 

loss of GPS, and low battery levels.

Operating Manual –

Power – The Hex and its ground control station are both powered by a Lithium polymer 

rechargeable battery pack. A new battery has a fully charged voltage of approximately 25.1V.

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 field with the field repair kit 

Command and Control Systems - The Main Controller (MC) is the brain of the system. It 

communicates with the IMU, GPS/Compass, ESCs, and RC transmitter to carry out autopilot 

functionality. The Main Controller has a USB interface for configuration and firmware 

updates via a PC. The Inertial 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/Compass 

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

entire Controller system and receiver separately, a battery voltage monitor, and CAN-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 detected 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 conditions uploaded before launch. This is 

accomplished without input from the operator.
