16-years-old kid created Starlink prototype and made $300,000
It capture the signal from satellite, and works anywhere
SpaceX tried to shut him down, but the kid was already covered.
Here's how he made it using nothing except Claude:
He's not stealing internet from Starlink.
He's using the radio beacons SpaceX broadcasts as a free positioning system that works when GPS doesn't.
Every Starlink satellite emits a constant beacon.
With a small dish and a $35 radio, you can pick them up and triangulate your location anywhere on Earth, even where GPS is jammed or blocked.
The US Army is testing the same concept.
The kid built a portable version and sold it to hikers, sailors, and emergency crews.
Step 1.
Order the hardware.
RTL-SDR Blog v4 USB receiver ($35)
Small Ku-band parabolic dish (~$50)
Ku-band LNB downconverter ($20)
Raspberry Pi 5 (8GB)
Bias-tee adapter
5000 mAh USB battery
Total around $180.
Step 2.
Flash Raspberry Pi OS Lite to the SD card and boot the Pi.
Step 3.
Install the SDR tools in Terminal:
sudo apt update
sudo apt install rtl-sdr gnuradio python3-numpy
Step 4.
Mount the LNB at the dish focal point.
Connect LNB to bias-tee, bias-tee to SDR, SDR to Pi via USB.
Step 5.
Open Claude Code and paste this prompt:
Write me a Python program that captures Starlink satellite beacons through an RTL-SDR and uses them for positioning.
Hardware: RTL-SDR Blog v4 Ku-band LNB parabolic dish.
Requirements:
Scan Ku-band downlink frequencies for Starlink beacons.
Identify each satellite using public TLE data from
celestrak.com.
Use Doppler shift from at least 3 satellites to compute position.
Output latitude, longitude, and accuracy to a small OLED screen.
Use pyrtlsdr, skyfield, numpy.
Add comments so I can tune the math.
Step 6.
Run the program.
The Pi locks onto satellites overhead and shows your coordinates with around 10-30 meter accuracy.
No GPS, no cell signal, no internet needed.
The kid 3D-printed a case, branded it as "GPS backup for hikers and sailors," and sold 350 units at $899 each.
Cost per unit: $180.
Profit per unit: $719.
His customers are wildfire crews, bush pilots, backcountry skiers, and yacht owners.
SpaceX has no legal issue with passive reception of public beacons.
The kid's lawyer confirmed it in advance.
