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.
