Thayer School’s Modular Approach to Micro-Satellite Design

Student Initiated Project Fall 1999, idea presented to develop small satellite for HAM radio communications Effort expanded to become ongoing program of spacecraft design at Thayer School Currently 8 students

DARTSat Student Team Members

Deployment Vehicle

System Level Specifications 10 cm Cube prior to deployment Weight < 2 kg Approximately 1 year orbital life Battery/Solar Cell power system Satellite to Ground direct communication Standardized Bus capable of operating generic experiments/modules.

DARTSat Services Bus A functional base module providing –Control and Data Handling –Power –Radio/Communications Approximately 2/3 total mass and volume of satellite

Opportunity Opportunity for student and faculty to conduct research/experiments in a Low- Earth Orbit space environment. –Faculty research –Graduate research –Student B.E. projects Continuing design and testing opportunities for CPR module.

Structural Design Stresses Modularity

Possible Payloads Auroral Research Low Earth Plasma Environment Mapping Unique GPS Applications Zero Gravity Micro-Machine Testing Distributed Research and Communications Constellations High School Designed Learning Experiences (no mice!!!)
