  1. TCSP – Design Constraint Analysis

  2. Design Constraints • Primary Constraints • Weight • - Component Size • Power Consumption • Secondary Constraints • Navigational Accuracy • Interfacing

  3. Microcontroller • Freescale MC9S12A64CFUE • HCS12 Architecture • QFP 80 package • 2x SCI, SPI, I2C, 8ch PWM, 8ch Timer • 64K Flash, 4K RAM • 59 I/O pins

  4. Navigation • Garmin 15L GPS Module • < 3m Position • < 5m Altitude • Small, uses external antenna • Hitachi HM55B Compass Module • 5.5 degree accuracy • Previously used • Cheaper than other modules

  5. Camera • HP Photosmart R707 • Can already control • Can be mounted to plane and balanced • Free

  6. Plane Upgrades • Mega 16/15/4 Brushless Motor • Fits in existing motor slot • Recommended by many RC plane • enthusiasts • Upgraded Battery • Lithium Polymer • 1100 -> 3300 mA-hr
