ADS-B in, ADS-B out & ADS-R (rebroadcast) 

# data[].attributes.body
ADS-B In provides weather and traffic position information delivered directly to the cockpit of equipped aircraft. It also enables access to graphical weather displays,significant weather activity notice, text based advisory and notices to airmen. It also helps with shared situational awareness and  critical see-and-avoid capabilities

ADS-B Out broadcasts information about your aircraft's go's location, altitude, ground speed and other data, to ground stations or other ADS-B in equipped aircraft.  With sufficient ADS-B equipped aircraft, locating an aircraft even amidst obstacles in irregular terrain is possible due to the nature of ADS-R.

ADS-R rebroadcast
ADS-R is a client based service that relays information from an aircraft on one link to aircraft equipped with ADS-B In on the other link.

Any Airspace that requires the use of a transponder today will on January 01,2020 also require aircraft to be equipped with version 2 ADS-B Out system

# data[].attributes.attachment_link.readable_text
Starting January 1, 2020, you must be equipped with ADS-B Out to fly in most controlled airspace:

Class B

Generally, from surface to 10,000 feet mean sea level (MSL) including the airspace from portions of Class Bravo that extend beyond the Mode C Veil up to 10,000 feet MSL (e.g. SEA, CLE, PHX)

Class C

Generally, from surface up to 4,000 feet MSL including the airspace above the horizontal boundary up to 10,000 feet MSL

Class E

Above 10,000 feet MSL over the 48 states and DC, excluding airspace at and below 2,500 feet AGL

Over the Gulf of Mexico at and above 3,000 feet MSL within 12 nautical miles of the coastline of the United States

Mode C Veil

Airspace within a 30 NM radius of any airport listed in Appendix D, Section 1 of Part 91 (e.g. SEA, CLE, PHX) from the surface up to 10,000 feet MSL

Any airspace that requires the use of a Transponder today will on January 01, 2020 also require aircraft to be equipped with a Version 2 ADS-B Out system. This can be either a 1090ES (DO-260B) ADS-B system or a UAT (DO-282B) ADS-B system.

For aircraft operating above FL180 (18,000 ft.) or to comply with ADS-B mandates outside the United States, you must be equipped with a Mode-S transponder-based ADS-B transmitter. For aircraft operating below 18,000 ft. and within the United States ADS-B rule airspace, you must be equipped with either a Mode-S transponder-based ADS-B transmitter or with UAT equipment.

The FAA has mandated a deadline for compliance for operators that intend to fly in most controlled airspace. January 1st 2020 is fast approaching and many operators like FedEx, Up's are early adopters but by the deadline it becomes mandatory for all operators.

# data[].attributes.attachment_link.readable_text
By January 1, 2020, you must be equipped with ADS-B Out to fly in most controlled airspace. Federal Regulations 14 CFR 91.225 and 14 CFR 91.227 contain the details.

Is perhaps the next phase of modernization for air transportation, devising a means to safely accommodate a larger number of flight vehicles both on the tarmac and in the Air.

The primary approach is to empower ATC with more sensitive and capable systems while reducing the workload by shifting to trajectory based monitoring. Trajectory based monitoring allows air traffic controllers to focus on critical phases of flight instead of the entire flight while crew in cooperation with Artificial Intelligence with the input from ADS-B systems navigate safely between those points.

NASA LOOKS TO BLOCKCHAIN FOR ENCRYTING ADS-B

NASA Looks to Blockchain for Encrypting ADS-B

Ronald J. Reisman, Aero-Computer Engineer at NASA Ames Research Center, published a paper this week proposing blockchain networks and the smart contract format popularized by Ethereum to possibly mitigate privacy concerns related to Automatic Dependent Surveillance Broadcast (ADS-B).

ADS-B is system that relays satellite telemetry data between aircraft to aircraft and from aircraft and ground stations. It is slated as the eventual replacement of the ground-based radar systems implemented today with the future GPS-based NextGen air system. The automatic and broadcast portions of its name point to its continuous transmission of aircraft data. NASA's research aims to alleviate concerns among industry stakeholders and operators about the privacy of end users and the security of the system from attack.

"It is widely recognized that there are still unsolved issues that complicate ADS-B adoption for stakeholders" Resiman stated in the paper going on to list security issues like spoofing and distributed denial of service attacks (DDOS).

The paper proposes a lightly permissioned blockchain framework, which will split the data between a layer where all participants share permissible data and one where data are secured and only accessible the appropriate parties under strict conditions. This allows for the privacy of not only private industry and civilian operators, but also allows for military aircraft to share their position without having to divulge their identity. It implements this through a permissioned Distributed Ledger Technology (DLT) where all participants on the network can access the public layer of the ledger and every transaction (in this case broadcast) in its history.

NASA isn't the only entity looking into establishing a secure framework for real-time airspace mitigation and aircraft tracking. Last week. AirMap, Kittyhawk.io, and Wing broached these concern s while announcing their work on an InterUSS network-based remote ID platform.
