ICAO Block Upgrades

The International Civil Aviation Organization’s (ICAO) Global Air Navigation Plan (GANP) presents a framework for harmonizing avionics capabilities and the required Air Traffic Management (ATM) ground infrastructure as well as automation. The framework is the Aviation System Block Upgrades (ASBU).

The ASBUs provide a roadmap to assist Air Navigation Service Providers (ANSP) in the development of their individual strategic plans and investment decisions with a goal of global aviation system interoperability. The ASBUs allows ANSPs to advance their air navigation system based on their individual operational requirements.

Below is a detailed description of the correlation between Aireon’s space-based Automatic Dependent Surveillance-Broadcast (ADS-B) system and the ASBU.

Performance Improvement Area 2: Globally Interoperable Systems and Data – Through Globally Interoperable System Wide Information

Flight and Flow Information for the Collaborative Environment (FICE)

Space-based ADS-B will enable FICE across different air traffic service units within an ANSP and even across ANSPs because of consistent surveillance information that can be provided to all.

Performance Improvement Area 3: Optimum Capacity and Flexible Flights – Through Global Collaborative ATM

FreeRoute Operations (FRTO)

Space-based ADS-B will allow reduced separation in remote airspace and can fill in gaps caused by line-of-sight issues enabling Free‐Route Operations (FRTO).

Network Operations (NOPS)

Space-based ADS-B will enable NOPS and Air Traffic Flow Management (ATFM) across different air traffic service units within an ANSP and even across ANSPs because of consistent surveillance information that can be provided to all.

Alternative Surveillance (ASUR)

Space-based ADS-B will provide a surveillance source for search and rescue that will fill in gaps caused by line-of-sight.

Optimum Flight Levels (OPFL)

Space-based ADS-B will allow for increased access to optimum flight levels through reduced separation for all ADS-B Out aircraft in oceanic and remote airspace.

Safety Nets (SNET)

Space-based ADS-B will provide a surveillance source for conflict-alerting and minimum-safe altitude warnings in remote airspace and can fill in gaps caused by line-of-sight issues.

Performance Improvement Area 4: Efficient Flight Path – Through Trajectory-based Operations

Continuous Descent Operations (CDO)

Additional surveillance can be provided by space-based ADS-B to allow for the creation of new procedures where permitted.

TrajectoryBased Operations (TBO)

Improved surveillance from space-based ADS-B will allow for increased monitoring in oceanic and remote airspace to enable TBO.

Remotely Piloted Aircraft Systems (RPAS)

Space-based ADS-B will provide a surveillance source for conflict-alerting and minimum-safe altitude warnings in remote airspace and can fill in gaps caused by line-of-sight issues.
