Töösisu kirjeldus
The radio system is the voice of the spacecraft. Your mission is to design, build, and tune the high-speed communication systems that allow our satellite to talk to Earth from hundreds of kilometers away. You will be responsible for the entire physical "link," ensuring that weak signals are amplified, interference is filtered out, and our data arrives home intact. The role is voluntary and unpaid, primarily remote with occasional in-person collaboration when required in Tartu Observatory.
Ootused kandidaadile
You will take ownership of the wireless heartbeat of the satellite. Your responsibilities include:
Design the transmit and receive chains, including filters, low-noise amplifiers, and power amplifiers.
Create the Engineering Model schematics and layout for a dedicated radio board using high-frequency design techniques (impedance matching, EMI shielding).
Ensure the radio board is compatible with the rest of the satellite, managing power requirements and data interfaces with the On-Board Computer.
Select and test individual RF components to verify they meet performance specs under stress.
Use advanced tools to measure VSWR, Gain, and Signal-to-Noise Ratio to ensure the hardware is ready for the vacuum of space.
RF is often called "black magic," but we just need someone with a solid grasp of physics and a methodical approach to testing.
We expect:
Plan your work and communicate it with your team leader
Consistent contribution to your tasks - weekly 8 to 10 hours
Timely communication of the task progress
Consistently documenting your development
Võimalused
You will gain:
Experience with PCB tools like KiCad with a focus on high-speed or RF layout.
An understanding of radio fundamentals: modulation (FSK, BPSK), link budgets, and Smith Charts.
Hands-on experience with Software Defined Radio or traditional HAM radio hardware.
Comfort using lab gear like a Vector Network Analyzer and Spectrum Analyzer.
A "test-early, test-often" mindset to catch interference issues before they reach the launchpad.
