What's that CubeSat Satellite stuff anyhow? (WHY2025)

CubeSats are small satellites comprised of 10x10x10cm "units" and range in size from very small 1U or smaller PocketQubes to 24U beasts. What can be achieved with such a satellite platform and why? I will go in to a brief history with examples from customers and amateur radio CubeSats. During my 20 years working with CubeSats, starting with designing parts of the Delfi-C3 student satellite in 2005, I have seen many missions and I have been involved in the design of quite a few CubeSats. Often, people ask me "what can you do with such a small satellite" and that prompted me to create this talk!
