20:30, 18 August 2025 Aircraft-navigation-signal-ADSB.png (file) 101 KB Jesternofool Time domain display of an aircraft Mode S or ADS-B transmission. Such transmissions are roughly 120 usec long and consist of 1 usec long bursts encoded with pulse position modulation (PPM) modulated onto the carrier using on-off keying (OOK). 1
20:27, 18 August 2025 Aircraft-navigation-signal-ModeAC.png (file) 73 KB Jesternofool This is a Mode A or Mode C transmission. It's a roughly 21 usec transmission consisting of up to 14 bursts. This was captured with a RTL-SDR at 2.4 MHz, then upsampled to 24 MHz to smooth out the time domain display. 1
