Template Notes:

• You can reformat this template to fit your design, but you must cover all the information requested on the following slides

• This template contains all of the information you are required to convey at the CoDR level. If you have questions, please contact me directly:

CoDR

Template Notes:

• The Goals of the CoDR are to Confirm that:– Science objectives are understood and

well-defined– Preliminary mission requirements are

defined and traceable to science objectives– Understand concept of operations– Technology dependencies and alternative

strategies for achieving science objectives

CoDR

Mission Overview: Mission Statement

• Mission statement• Break mission statement down into

your overall mission requirements• What do you expect to discover or

prove?• Who will this benefit/what will your

data be used for?

6

CoDR

Mission Overview: Theory and Concepts

• Give a brief overview of the underlying science concepts and theory

• What other research has been performed in the past?– Results?

7

CoDR

Mission Overview: Mission Requirements

• Project requirements derived from mission statement– Break down into mission objectives, system

level objectives (example on following slide)• Minimum success criteria

– What is the least amount of data you can collect that will still constitute a success?

CoDR

Example of Mission Requirements:

• The payload shall conform to the requirements set forth in the RockSat-X User Guide

• The system shall measure the numerical density of charged particles in the upper atmosphere from 30±5 km to 50±5 km

• The system should measure the numerical density of charged particles in the upper atmosphere from 30±1 km to 50±1 km

Shall is legally binding and indicative of minimum success

Should are an ideal metrics of performance that would lead to better science/performance, but are not required for minimum success.

Mission Overview: Concept of Operations

• Based on science objectives, present a diagram of what the payload will be doing during flight, highlights areas of interest

• Example on following 2 slides

Mission Overview: Expected Results

13

• This is vital in showing you understand the science concepts

• Go over what you expect to find– Ex. What wavelengths do you expect to

see? How many particles do you expect to measure? How well do you expect the spin stabilizer to work (settling time?)? How many counts of radiation? etc

2013

CoDR

Design Overview

14

• Utilization of heritage elements (designs/features used on previous flights) defined. How will you be modifying them for your specific mission?– Will you be using stacked

configuration, makrolon, same type of sensor as a previous flight?

• Major technology dependencies: what kind of sensors will you need?– What do the capabilities of the sensors

need to be? (ex. For an optical sensor, what wavelengths should it be able to detect? This is based on project requirements)

CoDR

Design Overview: Functional Block Diagrams

• Functional block diagram– Shows how systems interact with each other– Mechanical – will show how payload is

configured, especially if there are sensors external to the payload

– Electrical – shows how data will be recorded, stored

• Example on following slide • I will spend a lot of time on this diagram with

each team and it will be referred to all the way up until launch so make it good

CoDR

Design Overview: Payload Layout

• Initial drawings / layout on deck• Preliminary idea of how and where things will be mounted• Show where electronics boards (~how many?), sensors,

power will be mounted– A little more organized than functional block diagram (actually

shows standoffs, spacing between elements, etc)

18

This is NOT required at the CoDR level. If you can include this, you are ahead of the game!

CoDR

Design Overview: RockSat-X User’s Guide Compliance

19

• Rough Order of Magnitude (ROM) weight estimate• Estimate on payload dimensions (will it fit in the

payload space?)• Deployables/booms?• How many ADC lines?

– Do you understand the format?• Asynchronous use?

– Do you understand the format?• Parallel use?

– Do you understand the format?• Power lines and timer use?

– What do you know so far?• CG requirement

– Do you understand the requirement• Are you utilizing high voltage?

CoDR

Design Overview: Shared Can Logistics

20

• Who are you sharing with?– Summary of your partner’s

mission (1 line)• Plan for collaboration

– How do you communicate?– How will you share designs

(solidworks, any actual fit checks before next June)?

• Structural interface – will you be joining with standoffs or something else (again, be wary of clearance)?

Management

21

• Team organization chart• Preliminary schedule for the

semester• Monetary budget• Team mentors (industry, faculty)?

Don’t let the schedule sneak up on you!

2013

CoDR

• Restate mission• Issues, concerns, any questions• Plan for where you will take your design

from here?– Anything you need to investigate further?– Are you ready make subsystem and lower level

requirements to come up with a rough-draft design for PDR?
