Facts About the Illinois Observing Nanosatellite (ION) |
ION is…
• The University of Illinois at Urbana-Champaign’s first student-developed
satellite
• The first satellite completely developed in the state of Illinois …as far
as we know
• A fully independent spacecraft
• A double CubeSat (smaller than a shoebox at 4” x 4” x 8”)
• Launching from Baikonur, Kazakhstan using the Russian DNEPR-1 launch
vehicle, a converted ICBM
ION was built…
• Entirely by U of I students including project leadership, design,
development, and testing
• Over the course of four years
• By 100 students across 7 engineering disciplines including Electrical,
Computer, Aerospace, Computer Science, Mechanical, Theoretical and Applied
Mechanics, and General Engineering
• By a combination of undergraduate (3/4) and graduate students (1/4)
ION’s missions include…
• Measuring molecular oxygen airglow emissions in the Earth’s mesosphere
• Performing the first space test of Alameda’s micro-vacuum arc thrusters
• Performing the first space test of Tether Application’s SID processor
board
• Performing Earth imaging using a CMOS camera
• Demonstrating attitude stabilization on a CubeSat
ION has…
• A photometer, a CMOS camera, batteries, solar panels, a processor, memory,
an antenna, a radio, a modem, thrusters, torque coils, a 3 axis magnetic field
sensor, temperature sensors, voltage and current sensors, etc…
• A custom power system, attitude control system, operating system, file
system, and communications protocol
• A ground station on campus with an active antenna tracking system
ION went through…
• Functional testing
• Environmental testing including vibration and thermal-vacuum
• Integrated system operational testing
• A bake out procedure
ION’s space development challenges include…
• Overcoming strict resource limitations on space, mass, power, data
transfer, expertise, and funding
• Protecting components from radiation that causes upsets and erosion
• Avoiding depressurization problems (out gassing) that leads to component
failures and clouded optics
• Adjusting for Doppler shift in communications frequency as the satellite
passes overhead at 8 km/s
• Distributing heat without air convection
Students working on ION learn…
• Specific technical skills in their specialty area
• How to build complex systems like satellites
• To work with engineers from other disciplines
• To work on a large multi-team project
• Teamwork, leadership, formal and informal communication skills
The CubeSat community…
• Has over forty universities registered with plans to develop CubeSats
since about 1999
• Cooperates to launch hardware together and shares technical information
openly
• Has launched six CubeSats so far with 14 planned on the next launch
(including ION)
• Can perform high risk missions that commercial and government
organizations cannot
• Can develop satellites in as little as 1 to 2 years
