Mission: To test the abiliNes of a commercially available compact uncooled microbolometer array to capture and downlink infrared images of Earth’s oceans and atmosphere
Structure [STR] § COPPER will uNlize the CubeSat Kit 1U
Skeleton Structure, Revision D § The top face will be a customized solid
plate
Power [PWR] § Powered by the ClydeSpace 1U
Electronic Power System § Uses 10 W-‐hr Lithium Polymer baZery § Solar panels developed in-‐house will
cover five sides of COPPER to generate 1.5 W of electricity
Thermal [THM] § Requires no acNve thermal stabilizaNon § COPPER will be monitored for thermal
acNvity for troubleshooNng purposes
Ground OperaNons [GOP] § SLU students will operate COPPER when
the satellite is in orbit § CommunicaNon will occur over Santa
Clara University’s network
Command & Data Handling [CDH] § TI MSP 430 and CubeSat Kit Flight Motherboard used for data storage and transfer
§ Pumpkin Salvo Real Time OperaNng System used to manage sobware
CommunicaNon [COM] § Microhard, Inc MHX 2420 2.4 GHz Frequency Hopping Spread Spectrum Modem transfers main data to the ground at 9600 baud
§ Stensat Radio Beacon 430MHz to 440 MHz UHF beacon for quick health snapshot at 1200 baud and tracking
§ Custom patch and UHF antennae developed by AstroDev
Aftude DeterminaNon & Control [ADC] § Passive on-‐orbit stabilizaNon along Earth’s magneNc field lines using permanent magnets and hysteresis material
§ Flir Tau 320 will to face the Earth over the northern hemisphere
Image of IR Earth used from public domain images, property of goes.gsfc.nasa.gov
Payload [PLD] § COPPER is an infrared imaging system, providing the maiden flight for the Flir Tau 320 uncooled microbolometer array
§ Using a Xilinx Spartan-‐3 FPGA with an in-‐house developed hardware design to capture images from the Tau 320
On-‐Orbit OperaNons § Once in orbit, COPPER will image the northern hemisphere
NASA CubeSat Launch IniNaNve § Launch in March 2012 as auxiliary payload on the ELaNa IV mission, which will fly on the Falcon-‐9 CRS-‐2
§ Must be delivered to California Polytechnic State University for tesNng and integraNon ninety days before the launch date
