They use multilateration, but there's no GPS synced clocks needed. They use ADS-B messages with position as reference and uses the relative arrival times of those messages to model the clock characteristics of each receiver. That way all you need is an inexpensive receiver (like a RTL-SDR) and with enough receivers in an area you'll get pretty good position estimates of aircraft only transmitting Mode S messages. This is the most popular mlat server software, used by ADS-B Exchange among others: https://github.com/adsbxchange/mlat-server

I have a receiver that I use to feed the ADS-B Exchange network. In return I get an API key that I use to power a collection of twitter bots that tweet whenever they detect, in realtime, aircraft circling over various metro areas: https://twitter.com/SkyCirclesLA https://twitter.com/SkyCirclesSF https://twitter.com/SkyCirclesDC The bots have detected police and news helicopters and fixed wing aircraft, military aircraft (https://twitter.com/SkyCirclesSF/status/1227832420918935552), blimps (https://twitter.com/SkyCirclesLA/status/1213310909302493184), autogryos (https://twitter.com/SkyCirclesLA/status/1216464781869121536), power line inspection helicopters (https://twitter.com/SkyCirclesLA/status/1210280545952776193), and helicopters filming race cars (https://twitter.com/lemonodor/status/1228100397337702400).

mpletely uncensored, global aircraft tracking network. And it's powered by a considerable amount of specialized open source software. Even the multilateration client (https://github.com/adsbxchange/mlat-client) and server (https://github.com/adsbxchange/mlat-server) code that can determine an aircraft's position even when it's not broadcasting its coordinates, using the time-of-arrival information from multiple receivers, is online. tar1090 (https://github.com/wiedehopf/tar1090) is a much more efficient replacement for the old Virtual Radar Server front-end that is currently under development, and can be tried at https://tar1090.adsbexchange.com/
