It uses a PIC18F2550 to decode ADS-B pulses received by a modified SAT tuner and demodulated by an Analog Device AD8307 log amplifier.
It is spited it in three parts.
- A home made receiver front end which converts the 1090MHz carrier pulse modulation signal to a low frequency logical signal.
- A µprocesseur decoder which decodes the logical signal and converts it to its hexadecimal representation, or more.
- A Windows program that will display the basic data send through the decoder serial output."; function tShowHide(id, show) { var s = document.getElementById("desc"); if ((s.innerHTML.length<=212 || show==1) && show!=2) { s.innerHTML = fDesc[id]; if (document.getElementById('m1')) document.getElementById('m1').style.display='none'; if (document.getElementById('m2')) document.getElementById('m2').style.display='none'; if (document.getElementById('more_txt')) document.getElementById('more_txt').style.display='inline'; } else { s.innerHTML = ''; } }
