1. CubeSat for Ions, Neutrals, Electrons and Magnetic Fields PI Robert Lin, SSL Project Manager Thomas Immel, SSL System Engineer David Curtis, SSL STEIN Scientist Davin Larson, UCB MAGIC Scientist Tim Horbury, ICL Imperial College London CINEMA

2. 9 summer UCB students on CINEMA team. 3 returning now. 4 students from IAUPR and 4 from KHU visited all summer. End of summer review held with all students +4 visiting from KHU with PI Current Mass Budget: 2.7 kg (not including harnessing or thermal materials) Electrical Power – Clyde Space EPS has been tested extensively w/3U battery – 8 Solar Panels constructed, 2 of 10 flight panels now produced. Torque coil and panel have now undergone shake test w/RBSP. C & DH – 3 dsPIC Dev Units, one for each of FSW, EE, and Attitude Control (ACS) groups – FSW 70-80% done Housekeeping, Transmit, Power, Background, I2C, MAG. Next more MAG, CMD and EXEC Radio Communication – S-band downlink patch antenna on 3 rd ETU: Applying for NTIA spectrum assignment. – Helium Radio receiver testing underway. ACS – Simulink control code now converted to C, running on PIC. Debugging issue with k vector determination. – Flight Sun Sensors have been tested extensively, now with new black paint.

3. Spacecraft Structure – Mockup of Chassis complete and in SSL 214. – Many updates have been made in response to antenna placement, torque coil changes, harnessing issues, P-POD fit. UHF antenna going to fabrication. STEIN (SupraThermal Electrons, Ions and Neutrals) – ASIC specification underway. Sensor design and layout complete. Dev boards fabricated and sensors tested by KHU. MAGIC (MAGnetometer from Imperial College) – ETU sensor and test board are complete and being tested. ETA 1 week. – Simplified plan for sampling ADC driven by dsPIC, not FPGA state machine. Other Components – Instrument interface board laid out complete and quoted, Gerber and drill files going to Imagineering October 1. Working parts list with local assembler ETA Oct 15. – FPGA spec, and now VHDL code developed in close collaboration with Imperial College. – S-band dual patch antenna/splitter/coax mechanical and electrical ETU being fabricated for system tests before purchase of Emheiser Radio. – Harnessing issues drove several mm move of avionics stack. – Consideration of high voltage P/S for STEIN to be breadboarded before PCB order.
