Mission OverviewObjectives / GoalsMeasure rocket speed and spin rateDetermine the rockets motion and flight pathDesign a stable platform to achieve clear images during flightSuccessfully retrieve the flight data wirelessly (post-flight)Obtain basic knowledge and understanding of the design requirements and obstacles in real world applicationsDesign Overview: Mechanical

Solid Works model of both UW, UM and Augsburg payload systemStabilized PlateOptical PortMotorPower SupplyCameraMain Sensor / Processor BoardUM PayloadAugsburg PayloadDesign Overview: Structure

Design Overview: StructureDesign and Testing:Based on last yearSolidworks AnalysisPlanned Vibrations Testing

Structure deformed under 25g vertical loadDesign Overview: Electrical

1.SYS.1 or 1.SYS.2 ComplianceDesign Overview: ElectricalPlate Stabilization:Data is extracted from two peripheral accelerometersAcceleration data is converted to velocity via the trapezoid ruleThe processor then compares current and new rocket velocitiesVelocities are converted to steps per second and transmitted to the motor controllerDesign Overview: Final

Expected ResultsBenefitsProvide Future Rocksat Groups:Stabilization system for experimentsAccurate data of flight parametersHigh quality clear images for future flightsAllow expansion for wireless transmission data post-flightFabrication: Mechanical

Final Integration

Lessons LearnedWhat did we learn from this experience:Do not procrastinateCommunication is key for a smooth payload integrationWords of wisdom for next years groups:Do not underestimate the size of projectInvolve underclassmenKeep constant communication with other group(s) in canisterHardest part:Coordinating presentations and reports for both groupsProgrammingIntegrating systems togetherWhat would we change:Less electrical design
