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

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
