750,000 messages per second! Imagine if each node knew where it was and all of its nearest neighbors. The receivers could filter and not send messages that are coming from planes closer to their neighbors! Distributed filtering of redundant messages FTW!
- sorenjan 4y agoYou need messages from multiple receivers for MLAT, I think they use messages with known plane positions to calibrate the MLAT solver since the receivers doesn't have a high quality common time source. Plus proximity doesn't mean you can see airplanes that are behind buildings, at low altitude, etc.
- phkahler 4y agoWhat is MLAT in this case? The planes transmit their location in the ADS-B message. They are filtering a lot of redundant message receptions from multiple receivers. I would assume the messages also include altitude and heading information, so locations can be predicted between message receptions.
- sorenjan 4y agoMLAT is multilateration, where they use the difference in time of arrival to multiple receivers with known locations to estimate the positions of planes that doesn't transmit their location using ADS-B but only use older Mode S. This is mostly small or military planes. https://flightaware.com/adsb/mlat/ https://flightaware.com/adsb/mlat/
