  1. A Minimal Size, Weight, and Power (SWAP) System Metadata Generation for Remotely Piloted Vehicle Sensors Team 4 Isaac Hoffman Carrie Fox Dan Toussaint PengXu Jared Jonckheere Facilitator: Dr. John Deller Sponsor: Air Force Research Lab

  2. Outline • Introduction • Background • Design Specifications and Descriptions • Design Solution • Risk Analysis • Project Management Plan • Summary

  3. Introduction • Current systems for RPVs not accurate enough • Video not synced with data • Data corresponds to RPV not sensor • Goal • Collect data and output it accurately • Allow for synchronization of the data with video • 150 grams and 75 cm3 • 5 Watts

  4. Background • Data Collecting and Processing • GPS • Needs minimum of four satellites for 3D position • IMU • Used to determine velocity and orientation • Computer-on-module(Gumstix) • Kalman Filter to integrate data

  5. Frequency of Data Output: • 30 Hz is the video frame rate • Size • The system must be small enough to fit in a storage bay on the RPV • Weight • RPV must be below max takeoff weight • Affects flight range • Power • Must fit in power budget of existing system • Allowable G range for IMU • Higher ratings decrease the effect of vibration on readings Objectives and Specifications

  6. Easy to read/write software • Linux and Robotic Operating System • Correct data output format • Key Length Value (KLV) • Motion Imaging Standards Board (MISB) • 601.4 • 902.10 • Proper enclosure to reach target specification • Small and lightweight • Durable Objectives and Specifications

  7. Proposed Design Solution • GPS and IMU Communication • Communicate with sensors. • Kalman filter • Interpolates location between GPS updates using IMU data. • KLV Data Output • Outputs data in KLV format over interface to existing system. • Control • Negotiates output rate with existing system. Controls processing rate of internal nodes.

  8. Proposed Design Solution • GumstixOVERO FE COM with Pinto TH board • 1.75 W power consumption • 76.2mm x 23mm x 8mm • 12.2 grams • Analog Devices ADIS16360 • 50 mW power consumption • 32 mm x 25 mm x 27 mm • 16 grams • MCPro EasyGPS Board with the LEA-6S • 114 mW power consumption • 17x22.4x2.4mm • 2.1 grams

  9. Risk Analysis • Temperature • Weather Interference • Software • Physical

  10. Project Management • Tasks divided into five subgroups • One team member in charge of each group • Electrical engineers in charge of hardware • Computer engineers in charge of software

  11. Budget • Two sources of funding • Air Force Budget (Max $3000)

  12. Budget • ECE Department Budget (Max $500) • Total Estimated Cost - $1008

  13. Summary • Intro/Background • Objectives and Design Specification • Proposed Design Solution • Risk Analysis • Project Management • Budget
