Backgrounds
MotivationsLower barrier to enter space business by lowering cost
Expand commercial use of spaceExpand market for aerospace industry in Chubu (central Japan) region
Test advanced technologies on orbitImprove performance of future large scientific satellite
Large satellites usually do not use untested technologiesEnhance cooperation between academic and industries in Chubu region
GoalReduce cost by a factor of 100
with “optimized” performance
Cost Reduction of Satellites
MiniaturizationTradeoff with functionalities and performance
Serious optimization of functionalities and performanceOptimum performance can be realized by taking advantage of technological advance
could be comparable with existing large satellitesSmaller imaging sensors → smaller lens and camera systems
Make use of commercial parts (for automobile)Reliable and low costSOC (system on chip) processors with SOI technologies
SOI = radiation hardDevelopment of satellite for commercial use
Standardization of parts and interfaceDesigned for mass productionReduce cost and time for satellite fabrications and assemblies
ChubuSat Instrument Development Projects
Project-based instrument development programNOT predefined laboratory work classMixture of students with different sets of interests, skills and expertise
science and engineering, theory and experimentwork together toward common goal
Hands-on experience on satellite instrument developmentDesign, testing systems and implementationProblem solving skills, project planning and management“Failure teaches success”
Best instruments may be launched into spaceEvaluation at each phase of projects

ChubuSat Project Examples
Satellite bus instrumentsImprovement of communication systems
power efficient, broadbandMission instrumentsNew commercial services using satellites
Microsatellite constellationcomplete coverage of entire Earth with modest cost
Consumer entertainmentArtificial auroraArtificial shooting star
Example: IridiumComplete coverage of entire Earth by 66 satellitesHuge initial cost hurts profitabilityLearn from failures
Microsatellites reduce initial cost by large factorsImproved profitabilityExpand use other than satellite phone
Common services world-wide
Communication Microsatellites
Consumer Entertainments
Expanding market by lower costExample: computer
Mainframe→“mini”computer→personal computer→tablet (smart phone)Invention of microprocessor for calculator
“App” business created by tablet (smart phone)Entertainment like games are major App business
Possible entertainment business with microsatellitesArtificial aurora or shooting star
Events for anniversaries or ceremonies for individuals and companiesSales of satellite pictures
~1000 JPY/pictureNeed to sell 0.5 million pictures
Project Management by Students
Everything will be managed by studentsAdvices and supports by staff membersTask sharing based on each member’s strength
Every member does not have to attend every activityProject theme for D2 students are predefined
Details are still up to studentsPlan another ChubuSat workshop (in cooperation with retreat)
What to discuss today in one hourMeeting datesPresenter for team presentations (can be more than one presenters)D2 (project theme is predefined)
To do listProject timeline
D1Brain storming of possible project themesProject timeline
Last Words…
from International Advisory BoardIndustry requires new employees broad views as well as solid expertise産業界は新人に専門知識だけではなく幅広い基礎知識を要求しているIndustry is looking for smart talents with excellent 5 senses and 6th sense企業が求める人材は、頭だけでなく5感に秀でる人、第6感を使える人
It is necessary to learn from broad experiencesいろいろな経験から学ぶことが必要ChubuSat program is a good example. Learn from your own mistakes (not trivial mistakes)ChubuSatプログラムはよい例、どんどん失敗して学べばよい
Hands on experiment is important. University of Colorado provides opportunities for student to produce something by themselves as well as nominal courseworkHands on experimentが大事。コロラド大では、座学だけでなく自分の手で作れる場を与えている
