What is realistically achievable with a 3U cubesat with an ion engine?
Cost of the satellite? Cost of the launch?
Time/cost to develop ion engine?
How many month/years would it take for an ion engine to boost a 3U cubesat from 600 km to 2000 km?
What is the altitude limit for an ion engine? Impractical to slowly cross the radiation belt?
Could a 3U cubesat with deployable solar panels power a 1 watt, 100 kHz, mode U/V transponder?
I would contribute $1000 to a fund raising campaign for a financially and technically viable plan to (for example) launch in 3 years and deploy a transponder in "high" orbit 2 years later.
I probably would not contribute to a fund raising campaign for a whizbang 3U cubesat destined for a 600 km orbit.
