3.  Where we were last time  What’s happening now  What we’ve changed  Where we are going  What is in our way  What? (Questions ;))

4.  Peripheral communication - Successful  Data acquisition platform – Recording acceleration data  Kalman filtering – Controls 315 project  Rudimentary algorithms – Integration of the accelerations

5.  Software  Positioning algorithms – rotation and translation  Hardware  Schematic capture  PCB layout and routing  Continuing to order and receive components  Systems  Continuing to analyze hardware requirements as the software development evolves, looking to catch issues early

6.  GE Presentation  Interaction between GPS module and IMU  Ignore GPS when it becomes “Intermittent” – IMU is independent  Use intermittent “good” GPS data to confirm or adjust the IMU data in real time.  Magnetometer  Touch Screen LCD  Battery Charging Capability

7. Live Stream

8.  Positioning algorithm  Gyroscopes  GPS  Magnetometer  Move the PC code to microcontroller

9.  Having the PCB fabricated – subsequently tested.  Adding the gyroscope and magnetometer data to the positioning algorithm  Able to track position with breadboard prototype before spring break

10.  Hardware Debugging  “Measure twice” before fabricating the PCB  Not feasible to expect no errors  Hours to be spent developing the software algorithms  Delays from waiting for parts
