  22. Things to Think About:

  23. Things to Think About: - Work effectively as a team - Remember center of gravity during drop while designing - Good designs can be ruined by how it’s dropped - Design must be strong enough to survive the trip to the scale

  24. And the Winners ARE? Colorado Space Grant Consortium

  25. Fall 2009 Team Video

  26. Announcements: - HW 03 Due Thursday - Proposals and Presentations are due 9/16/10 - Passwords

  27. Request For Proposals Colorado Space Grant Consortium

  28. What is an RFP? - There is a lot of money out there - There are a lot of ideas - Request For Proposal bring them together - Most satellites were at one time an RFP - Most of you will write or help write a proposal in your job - Now is your time to practice

  29. SEE RFP

  30. To Recap RFP: - Final weight shall not exceed 850 grams - Shall image the Earth or the Balloon during flight and shall record internal and external temperature - Must have an additional experiment http://www.parallax.com/html_pages/resources/custapps/app_nearspace.asp Chapter 8 - Must follow all the guidelines while writing proposal - Why and How – this is your plan and foundation for project - Using screen shots…

  31. So... - Take the ideas you came up with individually during the HW#2 - Start with these in your team and expand them during HW #3 - But…Keep It Simple Stupid (KISS Principle) - Start now! - You are writing a proposal not a request for proposal - Proposals September 16, 2010 - Launch is November 6, 2010 (60 days)

  32. What You Get… Plus - Foam core and insulation - Flight batteries - Hot glue and Al tape - Flight tube and flag - Switches

  33. Presentation: Presentation Templates - Final presentation should cover same items in final report

  34. Final Written Report: Design Document Template - You will write you team’s final report throughout the semester with our Design Document revisions - team video

  41. Requirements Colorado Space Grant Consortium

  42. Requirements:

  43. Requirements: -

  44. Requirements Definition Marcin Pilinski Chris Koehler Colorado Space Grant Consortium

  45. Requirements Level Anatomy of Requirements Mission Statement (aka Mission Goal) A very general description of the problem being addressed by the system. G Step 1: General definition. Subjective description and a few numbers Mission Objectives 3 to 5 general statements elaborating the Mission Statement. O Objective Requirements Quantify each objective: when, what, where, for how long 0 Step 2: Numbers and ranges. Focus in on defining the problem. System Requirements The system as a whole must perform to this set of specifications in order to meet the objective requirements, mission objectives, and mission statements 1 Subsystem Requirements Each subsystem must perform to these specifications in order to meet the criteria defined above. This part is done separately for each subsystem i.e. power, mechanical, computer, science, thermal. Step 3: Subsystems. Repeat step 2 for every subsystem, tracing from system requirements. 2

  46. An Example from Class: Icarus Goal (G1) The BalloonSat Aquintus shall ascend to an altitude of approximately 100,000 feet to carry out scientific experiments that will measure tilt of the satellite, forces acting upon it, wind speed, and solar energy to better understand the conditions in which high altitude observatories would be in. Goal (G1) The BalloonSat Aquintus shall ascend to an altitude of approximately 100,000 feet to carry out scientific experiments that will measure tilt of the satellite, forces acting upon it, wind speed, and solar energy to better understand the conditions in which high altitude observatories would be in. Goal (G1) The BalloonSat Aquintus shall ascend to an altitude of approximately 100,000 feet to carry out scientific experiments that will measure tilt of the satellite, forces acting upon it, wind speed, and solar energy to better understand the conditions in which high altitude observatories would be in. O1 (comes from G1) Construct BalloonSat to improve understanding of HA conditions at X-100,000 ft for under $YYY dollars by MM/DD/YYYY. O2 (comes from G1) Measure tilt in one axis and forces in the range of X mN to YmN as a function of altitude in the range of X-100,000. O3 (comes from G1) Measure wind speed perpendicular to one face of the BalloonSat and solar energy as a function of altitude.
