CINEMA

GENERAL NOTES

• 11 UCB currently students on CINEMA team.• In collaboration with students at KHU, visiting students from Puerto Rico.• Magnetometer from ICL• Started a Seminar class devoted to CINEMA• Current Mass Budget: Around 2.7 kg, harnessing and redesigns• Thermal Model: Analytical at SSL, FEA from KHU, check with Solidworks• Launch Provider: Still backup on NPP launch, alternatives

SUBSYSTEMS• Electrical Power

• Progress• Building Flight Panels• Vibration and Thermal Cycling of panels• Testing of Battery/ EPS

• Issues• Clean Room facilities• Interference with torque coils• Cracked Cell during Thermal Cycle

• Next Steps• Finish Flight Panels• Build High Voltage Power Supply

• C & DH• Progress

• Reviewing Commands• FSW

• Issues• Narrow down the amount

• Next Steps

SUBSYSTEMS• Radio Communication

• Progress• ETUs of both S-band and UHF antennas• NTIA Application

• Issues• NTIA process moving slowly• Problems connecting Coaxial Cable to Whip Antenna

• Next Steps• Finish NTIA Frequency Assignment• Purchase Radios/ Antennas• Redesign Whip Antenna

• ACS• Progress

• Torque Coils tested, new wire• Sun Sensors tested, refab of flight parts• Finishing simulation

• Issues• Varying settling times in simulation

• Next Steps• Integration of ACS and Flight Software• Speed up settling time• Assemble Flight Parts

SUBSYSTEMS• Spacecraft Structure

• Progress• ETU built, being used for harnessing, stack integration• Holes drilled into it as needed

• Issues• Hard to machine

• Next Steps• Slight redesign to make fabrication more precise.

• STEIN (SupraThermal Electrons, Ions and Neutrals)• Progress

• New detector/ ASIC• Issues

• Changes caused by the new hardware• Next Steps

• Addressing these

SUBSYSTEMS• MAGIC (MAGnetometer from Imperial College)

• Progress• Single axis ETU complete• Triple axis ETU in testing

• Issues• Behind Schedule

• Next Steps• Integrate with flight software

• Other Components• Instrument Interface Board is being assembled.• FPGA code fully simulated, waiting to run on the board.• Harnessing done in Solidworks, working with the mockup chassis
