3. Outline ► Project objective ► Requirements ► Constraints ► Uses and users ► Technologies considered and selected ► Milestones ► Difficulties and troubleshooting ► Resources ► Testing

4. Definitions ► RVT - Remote video terminal ► UAS - Unmanned aerial system ► GPS - Global positioning system ► PDA - Personal data assistant ► RS-232 - Serial profile standard for serial communications ► SIP - Soft input panel

5. Project Statement ► To design and construct an inexpensive prototype remote video terminal (RVT) that is capable of displaying video as well as important telemetry data from an unmanned aerial system (UAS)

6. Requirements ► Budget: $1,000 ► Weight: less than 2 kg ► Operation time: 2 hours ► Telemetry data read through RS-232 input ► Ability to determine own location ► Automatically acquires necessary signals ► Useable in varying conditions

7. Constraints ► Screen size and resolution ► Processor speed ► GPS refresh rate and accuracy ► Bandwidth of signals

8. Considerations ► Assumptions  Signals are provided without error  Data are provided in proper form  GPS data is correct and accurate ► Limitations  Weight limit  Screen size (viewable area)  Wireless (Bluetooth) range

9. Intended Uses ► Search and Rescue ► Military surveillance ► Farm observation ► Security Source: http://www.pcsar.org/images/index/main_picture_w520_h390.jpg

10. Intended Users ► Military personnel ► Search and Rescue personnel ► Farmers ► Law enforcement officers Source: http://www.meridianmagazine.com/exstories/images/Marine%20Taggart.jpg

18. Research Required ► C# Programming for Windows Mobile 5.0 ► Soft Input Panel (SIP)  Win32 Programming ► Video Display and Connectivity ► Transmission of RS-232 Signals ► Bluetooth Connectivity

19. Milestones ► Importing Telemetry Data  Host PC to PDA  GPS to PDA  Range and bearing processing ► Importing Video Data  Streaming to PDA ► Integration  Combine data into GUI

20. Evaluation

21. Risks Encountered ► Video Capture  Flygrabber incompatibility ► Interface of various components  Interfacing with C# language  GUI display via input panel ► Battery Life

22. Risk Management ► Alternate video capture solutions  Slingbox AV  Wireless video ► Evaluate power consumption  Extended-life batteries available  Specification Sheets ► C# Programming Sources  Independent sources  Microsoft database

23. Resources ► Personnel Resources  Amount of time each member has spent on the project

24. Resources ► Financial Resources  Amount of budget spent on selected components

25. Resources ► Initial Team Schedule

26. Resources ► Final Team Schedule

27. Testing ► Team testing ► Outside user testing ► Advisor testing

28. Suggested Follow-On Work ► Create “All-in-one” final product ► Incorporate security measures ► Ensure compatibility with military standards

29. Commercialization ► Viable ► More rugged ► Security implementation ► Signal compatibility  Military vs. Civilian ► Possible Cost ~ $1000  Further development necessary

30. Lessons Learned ► Communication  Team, advisor, client ► Budgeting  Time and money ► Documentation ► Programming languages and APIs

31. Summary ► After considering many technologies, the team decided upon several components that provide both simplicity of design for the team and value for Lockheed Martin. ► These combined to create a successful RVT that will meet the various needs of Lockheed Martin.
