Discone Antenna Hub 400MHz and up, 70cms, ADS-B by mkarliner - Thingiverse

The Discone antenna is remarkable in that it is capable of receiving and transmitting over a wide range of frequencies with good matching. Because of this, it is a good match for SDR receivers such as the popular RTL-SDR sticks.

Using KSQL, Apache Kafka, a Raspberry Pi and a software defined radio to find the plane that wakes…
Cats behave erratically, but generally display their displeasure by jumping on your face. The post describes how we can use open source streaming solutions (Apache Kafka), KSQL (streaming SQL engine) and a Raspberry Pi to process aircraft movements in real-time to determine which plane is upsetting my cat.

NextGen Reality Check: Problems Persist As FAA Installs Framework | Aviation Week, May 2018
"The infrastructure piece of the FAA’s NextGen air traffic control (ATC) modernization is “nearly complete,” Acting Assistant Administrator Pamela Whitley told an Air Traffic Control Association (ATCA) conference in Atlantic City, New Jersey. Other speakers described a U.S. national airspace system that has ongoing traffic-flow and congestion problems."

"Deployment of the nationwide ground infrastructure for automatic dependent surveillance-broadcast (ADS-B) is complete. DataComm, a capability that enables controllers and pilots to communicate by text messages, is operational at 57 airport towers; it now is being deployed to en route centers. SWIM (system-wide information management)—a data-sharing backbone the FAA uses to make flight, traffic flow, weather and other information available to subscribers—continues to add services, Whitley notes."

ADS-B Exchange – World's largest co-op of unfiltered flight data
Welcome to, a co-op of ADS-B/Mode S/MLAT feeders from around the world, and the world’s largest source of unfiltered flight data.  Thanks to our worldwide community of participants, if the data is broadcast over the air, you can find it here.  This opens up a whole new world of interesting traffic for hobbyists, without materially affecting security for anyone.

Spire Global is expanding cubesat constellation to offer persistent global view -
"Spire Global, the San Francisco-based company that operates 48 GPS radio occultation cubesats, could provide a persistent view of about 97 percent of Earth with a constellation of 150 satellites"

"A constellation of 100 to 200 radio occultation satellites, which provide detailed observations of atmospheric temperature and moisture, could be used in conjunction with geostationary weather satellites like NOAA’s Geostationary Operational Environmental Satellite-16 to dramatically improve the accuracy and spatial resolution of global weather prediction models, MacDonald said."

"Spire also is expanding its ground network. The company has 27 ground stations operating and is pushing to increase that number to 50 because the added ground stations will allow the firm to provide customers with data no more than 30 minutes old"

"In addition to using its spacecraft for meteorology, Spire’s cubesats carry Automatic Dependent Surveillance-Broadcast (ADS-B) payloads for aircraft tracking and Automatic Identification System (AIS) payloads for maritime tracking. “We collect about 10 million ship reports a day,” MacDonald said."

ADS-B Out ‘Non-Complying Emitters’ Occupy FAA | Commercial Aviation content from Aviation Week
"Two years out from its 2020 mandate to equip for automatic dependent surveillance-broadcast “Out” (ADS-B Out) position reporting, the FAA is grappling with a significant number of avionics that were installed improperly. And aircraft operators are lagging in equipping for the requirement, presaging a rush on repair stations as the mandate nears."

"By Jan. 1, 2020, aircraft flying above 18,000 ft. or internationally must be equipped with GPS and Mode S Extended Squitter (1,090 MHz) transponders and lower-flying airplanes in domestic airspace must have GPS and 978 MHz universal access transceivers to regularly broadcast their position—the function called ADS-B Out. Thus far, the FAA has not mandated ADS-B In, the ability to display air traffic on the flight deck, which requires costly software and display modifications."

"In response to a petition by trade group Airlines for America on behalf of its member carriers, the FAA in August 2015 issued Exemption 12555, which allows airlines to operate through 2024 using GPS receivers that do not meet required navigation accuracy and integrity performance standards. But they still must install Version 2 ADS-B Out transponders by the 2020 deadline. "

ADS-B Exchange – World's largest co-op of unfiltered flight data
Home – Serving the Flight Tracking Enthusiast
Welcome to, a co-op of ADS-B/Mode S/MLAT feeders from around the world, and the world’s largest source of unfiltered flight data. Thanks to our worldwide community of participants, if the data is broadcast over the air, you can find it here. This opens up a whole new world of interesting traffic for hobbyists, without materially affecting security for anyone.

In fact, ADSBexchange is proud to collaborate with C4ADS to support its mission to produce data-driven reporting to understand, prevent, and mitigate global c4logoblackconflict. Over the coming months, this partnership will yield more receivers in interesting and unusual global locations, ADSBexchange will have wider coverage and C4ADS will have more data to enhance their mission.

Although you can do it here, this is not the go-to site to track your grandmother’s flight from Cincinnati to Chicago so you can pick her up from the airport. For that, I recommend

ADS-B Exchange differs from typical flight tracking sites in two primary ways. First, all data sent in from the community is, in turn, made available back to the community through various archives and APIs. ( Best of all, for non-commercial use, all of this data is freely accessible to anyone!

How can airlines stop hackers pwning planes over the air? And don't say 'regular patches' • The Register
Via Dale Hatfield

See discussion thread:

"A plane was compromised as it sat on the tarmac at a New Jersey airport by a team of boffins from the worlds of government, industry and academia, we're told. During the hack – the details of which are classified – experts accessed systems on the Boeing 757 via radio-frequency communications."

"A couple of years ago, security researcher Chris Roberts was accused of hacking into the controls of a United Airlines plane in midair via the inflight entertainment system. Roberts tweeted about airplane network security during the flight to Syracuse, New York. He was questioned on arrival by the Feds. However, there is no evidence he accessed flight control systems, and no charges were ever brought.

In 2014, Brad Haines poked air traffic control and ADS-B security, and found various threats to installations."

"Recently designed commercial aircraft – such as Boeing’s 787 and the Airbus Group A350 – were drafted with computer security in mind, we're told, but resisting or preventing cyber-attacks were not on the design criteria list for older aircraft, which still make up the vast majority of airline fleets."

How to Track Government Aircraft 200 Miles Away with a Raspberry Pi « Null Byte :: WonderHowTo
Aircraft equipped with ADS-B are constantly shouting their location into the radio void, along with other useful unauthenticated and unencrypted data. In this guide, we will make an ADS-B receiver using a Raspberry Pi with a software-defined radio (SDR) dongle, which we can use to track aircraft anywhere in real time.
