What is all of this?
Automatic dependent surveillance-broadcast - Mode-S
With a $10 DVB-T card, $6 of RG6 coaxial cable, a $35 Raspberry Pi B+, and a massive $20 µSD card I can track flights in real time which happen to venture near my house. Because of this, my friends tell me I have an AWACS system in my extra bedroom.
You only need a few things to get started:
If you're still after more:
- You can make some kind of 1090 MHz Antenna, λ=257mm
- Then test the range of the antenna
- Try a Low Noise Amplifier(LNA) and filtered dongle, flightaware - prostick
- Experiment with gain/error correction settings on the SDR
- Move everything off to a Raspberry Pi
- Try to make a shorted quarter-wave (λ/4) stub filter
- Try a sawtooth filter and Low Noise Amplifier(LNA)
- Read some random things I wrote discovering this
