1. EE 491 Project Presentation May07-04 – PDA Based UAS Remote Video Terminal Team Members: Devin Carney Jonathan Farmer Matt Henkes Rene Rios Faculty Advisor: Zhao Zhang

2. Outline ► Project Objective ► Our Client ► Requirements ► Constraints ► Uses and Users ► Technologies Considered ► Technologies Selected ► Possible Difficulties and Troubleshooting ► Resources ► Testing

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

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

5. Requirements ► Budget: $1,000 ► Size: Less than 2 kg ► Operation Time: 2 Hours ► Telemetry data read through RS-232 Input ► Ability to determine own location ► Automatically acquire necessary signals ► Useable in varying conditions

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

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

15. Hardware Architecture

16. Software Architecture

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

18. Possible Difficulties ► Video Capture  Unfamiliar with Flygrabber technology ► Interface of various components  Bluetooth with RS-232, Video overlay ► Battery Life  Possible need for extended-life battery ► GUI Programming  Minimal experience with C#

19. Resources ► Personnel Resources  Estimated amount of time each member will spend on the project

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

21. Resources ► Team Schedule

22. Testing ► Team testing ► Outside user testing ► Advisor testing ► Client testing

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