7 Problems & Solutions

8 Untested hardware and software lead to crashes.
Problem Untested hardware and software lead to crashes.

9 Solution Simulate flight before actual flight to ensure success.

10 Problem Old trainer cockpits that aren’t useful anymore and don’t have a purpose.

11 First-person cockpit flight
Solution First-person cockpit flight simulator capable of training pilots.

12 Problem Weak connections between UAV and ground control station make communication difficult.

13 Solution Azimuth-elevation antenna tracking system allows for stronger connection and better communication with UAV and Ground Control Station.

14 Constraints

15 Technical Constraints First Person Cockpit
Movement Detection Controls should be read with miniscule degrees of change Compact Design Hardware components must fit inside of the cockpit with room to move controls

16 Technical Constraints Antenna Tracker
Antenna Accuracy Tracking system must ensure the antenna keeps UAV in range of the main lobe Operating Distance Operate within line of sight and have an unobstructed view Tracking Mechanics Gimbal must cover a range of 360̊ azimuth and 90̊ elevation within 40 seconds

17 Practical Constraints Sustainability
The connections and software used for the product will not constrict the systems ability to add new devices. Must not be specific to the Xipiter team and must allow for minimal hardware to adapt for the new devices. This implementation will add versatility to the system.

18 Practical Constraints Economic
Cockpit system: upgrade. HITL: open source software. The antenna tracking system: compatibility with the Xipiter team. Working with the Xipiter team gives additional access to parts.

19 Approach

23 Approach Ground Control Station
Mission Planner Popular open source software Xipiter team uses when planning missions Compatible with Pixhawk

24 Approach Flight Simulator
FlightGear X-Plane Mac, Windows, and Linux support Weather modeling and real world airports Allow system failures Aircraft customization or creation [5] 2.0 GHz quad core processor 2-4 GB RAM MB video card compatible with OpenGL 2.1 or higher Allow UDP connection to JSBSim Price: $ [6] Aircraft customization or creation [7] 3.0 GHz quad core processor 16-20 GB RAM 4 GB video card compatible with DirectX-11 Allow UDP connection to JSBSim [8] Price: $ [9]

25 Progress

26 Timeline August September October November December Research
Order Parts Hardware Assembly Software Development Testing Finalize Prototype Finishing up research of all 3 parts done ordering parts Assembling the last bit of hardware antenna tracker Finishing up HITL and Antenna Tracker software Testing cockpit has been successful HITL making progress Finalize prototype by beginning of December

27 Cockpit Hardware Progress
Have successfully simulated flight using all controls use carbon fiber to connect controls to pots have wired switches

28 Cockpit Hardware Progress
Used terminal blocks to create common gnd/pwr Coded the leonardo Now operates as joystick Calibrated input Close up of pots used L bracket epoxy arm to pot arm connected to “moving mechanical parts” rudder throttle 1&2 yoke

29 Antenna Tracker Progress
Gimble uses 2 servos repurposed boat winch servos can handle torque tested servos they still operate correctly attached top portion to gear correctly waiting on PixHawk Ubiquiti Nanostation M5 highly directional working with Xipiter for operation/testing

30 Software Progress Have simulations of the UAV and Antenna tracker working Using mavproxy, jsbsim, ardupilot on ubuntu side sending information to Mission Planner Windows side acts as our ground station good interface and information displayed in usable format
