1 Scope

My first QSO via QO-100 took place on 01.03.2019 with DF6NM at the portable station of my friend Severin DL9SW. Since then I wanted to acquire the capabilities to transmit to the satellite myself and receive it's signals.

In summer 2022 I met a trainee in my company who wanted to learn about satellite communication, and given that I am working in a satellite project for Airbus, it was apparent that there was a chance to build it.

In fact such a project gives me quite a number of topics that I can teach to our trainees:

  • Requirements Engineering
  • Mechanical Planning
  • Electrical Planning
  • Electrical Engineering fundamentals
  • RF Engineering fundamentals
  • Electrical Safety
  • Specifics of Satellite Radio Communications
  • Electrical Measuring
  • Software Defined Radio
  • Microcontroller Programming
  • Embedded Systems / Embedded Linux (Raspberry Pi)
  • Linux System Programming
  • Networking
  • GUI Design / Browser Engineering
  • Quality Assurance (IVV)
  • Practical Radio Operations

So this project is rather fruitful.
