Radiation hardening is a method of designing and testing electronic components and systems to make them resistant to damage or malfunctions caused by ionizing radiation (particle radiation and high-energy electromagnetic radiation), such as would be encountered in outer space, high-altitude flight, around nuclear reactors, particle accelerators, during nuclear accidents or nuclear warfare. Most radiation-hardened chips are based on their commercial equivalents, with some manufacturing and design variations that reduce the susceptibility to radiation damage. Due to the extensive development and testing required to produce a radiation-tolerant design of a microelectronic chip, radiation-hardened chips tend to lag behind the cutting-edge of developments.
For what it's worth, computer hardware flown in space is specially radiation hardened and redundant.
Is it possible to have a version of ArduSat as a means for two-way communication ? I found a number of projects that do satellite tracking. I didn't understand how could one just 'connect' to a satellite and communicate two-way without any fee involved. Perhaps, the fee part was implicit but, then, I got curious. Can I have "my own" satellite and the satellite tracking code ?Yes, I am a satellite n00b, so, please do feel free to throw manuals at me.
