ADSB....Automatic dependent surveillance—broadcast (ADS–B) is a surveillance technology in which an aircraft determines its position via satellite navigation and periodically broadcasts it, enabling it to be tracked. The information can be received by air traffic control ground stations as a replacement for secondary surveillance radar, as no interrogation signal is needed from the ground. It can also be received by other aircraft to provide situational awareness and allow self-separation. ADS–B is "automatic" in that it requires no pilot or external input. It is "dependent" in that it depends on data from the aircraft's navigation system.

ADS–B is being incorporated in various jurisdictions worldwide. It is an element of the United States Next Generation Air Transportation System (NextGen), the Airports Authority of India upgrade plans in line with the ICAO Global Plan Initiatives and Aviation System Block Upgrade (ASBU), and the Single European Sky ATM Research project (SESAR).ADS–B equipment is mandatory for instrument flight rules (IFR) category aircraft in Australian airspace; the United States requires many aircraft (including all commercial passenger carriers) to be so equipped by January 2020; and, the equipment has been mandatory for some aircraft in Europe since 2017.Canada is currently[timeframe?] using ADS–B for limited air traffic control, mainly in the Hudson Bay area.[8] Aircraft operators are encouraged to install ADS-B products that are interoperable with US and European standards, and Canadian air traffic controllers can provide better and more fuel efficient flight routes when operators can be tracked via ADS-B.

What's this happy horse poop on ADSB?

NIKK..Any idea what she's talking about??

Clueless.

Sounds like supplemental tracking.

I wonder if this ADSB can override, say, in a highjacking situation :-)

Interesting info....

NIKK—I checked her page and no one had any info for her either, to her question. Only one responded asking what was going on.

The screen shot has the info for a specific 737 jet on the left. On the right it says there are 7500+ aircraft in the air, but only shows the tracking for 20 of them.

That is basically all I could decipher.
