LEO satellite link (telemetry)
Advanced60 min
A telemetry link with a low-Earth-orbit satellite: very long distance, low power and Doppler shift.
What you get
A telemetry frame received across 1000 km, after correcting the Doppler shift.
Parts (simulated)
- Built-in RF/SDR lab
- Space channel model
- Doppler corrector
Nothing to buy: every component here is simulated in the browser.
Project steps
- 01Set the distance and transmit power.
- 02Observe free-space loss in the link budget.
- 03Introduce Doppler shift from the passing satellite.
- 04Choose a robust modulation and a suitable rate.
- 05Check the integrity of the received frame.
What you learn
- Free-space path loss
- Doppler effect
- Robustness vs throughput
- Telemetry framing
