  2. Our Client Todd Colten Engineering Team Lead Lockheed Martin Sky Spirit UAS

  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

  11. Technologies Considered RVT Position Manual coordinate entry GPS Video Input Video capture cards Wireless (802.11b) Telemetry Input USB inputs RS-232 Bluetooth Various PDA units

  12. Technologies Selected • PDA Dell Axim X51v - Built-in 802.11b - Bluetooth Capability -Dual channel - 480x640 Resolution - 3.7” Display

  13. Technologies Selected • Video Input Slingbox AV - Video capture - S-Video/RCA inputs - Wireless streaming

  14. Technologies Selected • GPS USGlobalSat BT-338 - Bluetooth Receiver - 72 hour battery life - Fast warm-up time

  15. Technologies Selected • RS-232 Transmission Bluesnap Bluetooth Dongle - Serial port profile - Simple interface

  16. Software Architecture

  17. Graphical User Interface (GUI) • Simple Interface • Easy to understand • Video display • Data overlay • Landscape or Portrait

  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.
