Started operation New Oceanic System （TOPS) in Feb 2019

Trajectorized Oceanic Traffic Data Processing System (TOPS) is a next generation system for oceanic air traffic control.

TOPS have started operation in February 2019.

TOPS provides,• data link functions which includes AFN, ADS-C and CPDLC;• AIDC messaging function between RJJJ and other ATSUs including Manila

ACC;• more accurate aircraft position data calculated from ADS-C report or position

report, with using dynamic weather data; and• more stringent conflict probe and support for decision making for controllers.

TOPS has new features which support,• PBCS framework;• ADS-C Climb and Descend Procedure (CDP)*; and• ADS-B In-Trail Procedure (ITP)*.

*ADS-C CDP and ADS-B ITP will be supported from beginning of 2020.

Special Thanks for FAA’s support

We order to respond to an increase in the future traffic demand, conventional and different, to expand the ATC capacity by the airspace divided by altitude. ・By difference of cruising, climbing, and descending, we raise the treatment capacity of aircraft.・In the high altitude airspace of low workload, the handling number of aircraft makes to increase.

✓Handling ability of Air Traffic Control was raised by reducing number of aircraft per 1 sector by subdivision of a sector conventionally.✓However, enforcement of subdivision beyond this will increase the time and effort of taking over between sectors. Moreover, the airspace that detour for bad weather or turn order of an aircraft becomes less insufficient, and throughput declines conversely.
