Since then, we've added many new receivers and have seen increased interest in FlightAware's ADS-B Network. With this in mind we updated some aspects and wanted to reshare the content. In addition, we have new posts in the works that go deeper into the technical aspects of ADS-B engineering at FlightAware, so stay tuned! - Eric T. How It Started In the early 2000s, there was an emergence of a new aircraft surveillance technology known as Automatic Dependent Surveillance–Broadcast, or ADS–B. This new technology eventually replaced radar as the main surveillance method for tracking aircraft. Aircraft with ADS-B transponders obtain their location from GPS and broadcast it on the 1090 MHz and 978 MHz frequency, which allow air traffic control (ATC) to receive this data and use the information to manage nearby airspace. The original founders of FlightAware took advantage of this new opportunity and created an ADS-B receiver that could receive and process this raw flight data and forward it to FlightAware over the Internet. As technology developed over time, we’ve engineered more cost effective, performant receiver solutions that allowed us to scale our network to over 35,000 nodes across the world, all of which are hosted by a community of dedicated volunteers. What’s in our ADS-B Receivers? The Hardware The core components consist of a Raspberry Pi Computer, a USB RTL2832U Software Defined Radio (SDR), and a 1090 MHz antenna. We developed our very own line of SDRs, which we call the Pro-Stick and Pro-Stick Plus. While both models have built-in RF amplifiers to maximize ADS-B performance, the Pro-Stick Plus has a built-in 1090 MHz filter to reduce noise in high RF environments. FlightAware provides two ADS-B hardware solutions. The first is an open-source solution, called PiAware, that anyone can build themselves with full autonomy by gathering the hardware and loading FlightAware ADS-B decoding software on it. The other solution is called FlightFeeder, which is manufactured by FlightAware. The FlightFeeder is self-configuring and remotely managed by FlightAware, allowing us to provide software updates and troubleshooting support. http://zh.flightaware.com/squawks/view/1/recently/popular/95210/Blast_from_the_past_FlightAware_s_Terrestrial_ADS_B_Network http://zh.flightaware.com/squawks/view/1/recently/popular/95228/NTSB_rips_Boeing_for_failing_to_produce_key_door_plug_documents Wed, 06 Mar 2024 19:30:14 GMT Interesting read. One wonders what Boeing is trying to conceal if they won't turn over a list of names that worked on the faulty AS Max 9 door. http://zh.flightaware.com/squawks/view/1/recently/popular/95228/NTSB_rips_Boeing_for_failing_to_produce_key_door_plug_documents http://zh.flightaware.com/squawks/view/1/recently/popular/95229/Qatar_Airways_says_goodbye_to_Boeing_747_freighter Wed, 06 Mar 2024 20:34:26 GMT UPS is getting two young planes that are less then 11 years old. http://zh.flightaware.com/squawks/view/1/recently/popular/95229/Qatar_Airways_says_goodbye_to_Boeing_747_freighter
