1. Preliminary Design Review Metro State College of Denver Matthew Hanley, Daniel Bass 14 November 2008

2. User notes: –You may reformat this to fit your design, but make sure you cover the information requested in this template. –This template is the barebones of what is needed.

3. Mission Overview What is your objective –The objective our mission is to build a payload that will create an interest in the program at the Metro State College of Denver –This payload is going to take gyroscopic and acceleration measurements, as well as digital still photographs, and store them for later analysis

4. Mission Overview Cont. What do you expect to prove, discover, or learn from your experiment? –We expect to learn how to integrate a payload into the standard payload canister, as well as integrate with other payloads in a canister and rocket body –We expect to learn more about the behavior of a rocket in flight through the data we collect

5. Mission Overview Cont. Brief overview of underlying science/theory –We plan to emulate the payload we learned to build at the RockOn work shop in 2008 with some minimal configuration changes Changes include implementing a set of gyroscopes, and a digital still camera, and media storage

6. Mission Overview Cont. What other related research/experimentation has been done in the past? –This payload was built in the DemoSat IV mission as well as built for the RockOn Workshop in 2008 Results? –This mission has produced accurate reliable data in the past, that we used to correlate real time video of the payload using acceleration, gyroscopic motion and mathematics

7. Mission Overview Cont. Mission Requirements –We only require space to implement our payload in addition to an optical port to take digital still photographs –Our payload will also need to have a small sensor array as close to the central axis of the vehicle as possible

8. Sub System Requirements What subsystems do you have: power, C&DH, thermal, etc. –Power- Lithium polymer batteries –C&DH- PIC, logic control, SD card storage –Digital Still Camera with integrated SD card storage –Accelerometer and Gyroscope array

9. Sub System Requirements What requirements do you have for each subsystem. –Digital Camera- will need to be secured to the platter in alignment with the optical port. –Gyroscope array will need to be as close to the center of the vehicle as possible

10. Sub System Requirements -What requirements do each subsystem impose on each other. -Power Subsystem -Power subsystem shall supply 3 volts during the entire flight to C&DH -Power subsystem shall remain at environmental temperatures during the flight -C&DH -C&DH will require power the entire flight -Digital Still Camera (DSC) -DSC will require perfect alignment with the optical port -The arming system will arm the DSC and internal code will operate the DSC

11. Sub System Requirements (cont) Accelerometer and Gyroscope Array –This array will take the readings and send them back to C&DH to be stored –This array will be operated by C&DH

12. Sub System Requirements Which requirements are design drivers? –Power –Optical port alignment

13. Special Requirements (Multiple Slides) -I don’t believe we have any special requirements at this time

14. Overall Design Command & D.H. Gyros Lithium Polymer Batteries G Switch Accelerometers Digital Still Camera with integrated Media Storage Digital Storage Media

15. C&DH Design Microcontroller Gyroscopes (x,y) G-switch activation Gyroscope (z) Accelerometers (x,y) Gyroscope (z) Digital Still camera SD Media Storage

16. Drawings Drawings and Schematics are in process and will be done soon

17. Commands and Sensors (Multiple Slides) -What states can your payload be in? -Active, Active/Safe, Idle… etc. -Active and Active/safe, it will take data until it is full or runs out of memory

18. Commands and Sensors -The key items that we are looking for are data flow diagrams and budgets -Memory budgets - we are going to use two 1GB SD Cards -How many samples, how long, do you have enough memory? -Sample at 100hz, for 12 hours will give us 3MB of data -Where is data stored? SD Cards -How does the data get there? Through the PIC and some wires -What commands queue data acquisition? G-swtich activation

19. Test Plans (Multiple Slides) -What type of testing can be performed on your payload pre-flight? -100% runtime testing can be done -What is required to complete testing? -Complete construction of the hardware -Support Hardware -Will produce a can and purchase the incidentels -Software -in-house

21. RockSat Payload Canister User Guide Compliance (Could be one slide) Update Chris and I on User Guide Compliance since CoDR –Mass, Volume Estimated fraction of allotment vs. assigned fraction –Mass fraction may come in at 800grams, allotted 1.4Kg –Volume is going to be a challenge, allotted 2.35” height we are going to use aprroximatley 2.75 “ with the camera mounted to the plate –Payload activation? What have you planned for? G-switch How does it comply with Wallops “no volt” requirement –completely –Rocket Interface Shorting wires

22. Shared Can Logistics Plan (Could be one slide) Update Chris and I on RSPC sharing logistics since CoDR –Institutions/Universities in can University Northern Colorado, Colorado State University –Plan for collaboration on interfacing –Suppose to set up a meeting to collaborate Know relative locations in can –Especially important for payloads needing ports We need to be in the middle of the can to align the camera with the optical port, or at least the camera does, and the rest of the package can go somewhere else in the can –Structural interfacing to each other To the top and bottom bulkheads –We don’t have a problem using the standard can bolt pattern with the standoffs

23. Management –Updated Organizational Chart Matt Hanley, Project Leader Daniel Bass, Team Member –Updated Schedule- our schedule will follow the Colorado Space Grant Consortium schedule that was provided –Updated mass/monetary budgets We are still planning to spend $500.00 and still going to use about 800 grams

24. Conclusions –Issues and concerns Becoming more concerned with how integration between can users is going to work and placement inside may become a challenge –Closing remarks I can’t thank you all enough for the hard work you put into this for all of us. Thanks
