Company Profile

  • Harris Orthogon Product Portfolio

    To be competitive, airports can no longer only look at on-time departures, but need advance intelligent arrival flow data and departure harmonisation with Air Traffic Control (ATC) available TMA and Airside capacities. Both are being addressed by the International Civil Aviation Organization (ICAO) with the Aviation System Block Upgrades (ASBU) as well as Eurocontrol in the ATM Master Plan. The Harris Orthogon product portfolio recognizes this with its solutions for Air Traffic Synchronization and Airport Airside Solutions both being support by the Orthogon Integrated Visualization Suite.

  • Airport Airside Optimization

    The only predictable factor within the airport environment is the fact that airlines are very rarely in a position to fly their planned and published schedules. In combination with limited capacity, both in the air (airspace) and on the ground at the airport, this is leading to more and more flight delays impacting passengers and more and more regulations being put into place.

    Airport Airside Optimization Suite contains:

    • Demand Capacity Balancer (DCB)
    • Pre-Departure Sequencer (PDS)
    • Stand Optimizer
    • Airside Monitor
  • Air Traffic Synchronization

    Harris Orthogon has been the leading provider of arrival management and departure management solutions for ANSPs and airports for more than 30 years. The company is recognized worldwide by customers and Air Traffic Management system integrators as the leader and innovator in traffic synchronization solutions. The focus is on ICAO Aviation System Block Upgrades (ASBU) Thread Runway Sequencing (RSEQ).

    The Orthogon decision support systems were designed to improve operational performance and efficiency while operating in the very complex environments of the busiest airports and surrounding airspace. The concept of this suite is to generate planning advisories for air traffic controllers to improve ATC and airport operations.

    Air Traffic Synchronization Suite contains:

    • Arrival Manager (AMAN)
    • Departure Manager (DMAN)
    • Coupled AMAN/DMAN
    • Extended Arrival Manager (E-AMAN)
  • Integrated Orthogon Visualization tools

    With the ODS Toolbox™, Harris Orthogon has acquired a worldwide reputation as a specialist for air traffic Controller Working Positions (CWP) development software. Since its market entry in 1994 the ODS Toolbox™ has been accepted by many large Air Navigation Service Providers (ANSPs) and system integrators as the tool of choice for graphical user interface development.

    The ODS Toolbox™ is a precursor and prepared the development and market entry of the newly developed ODS™ Open Platform, which became the standard user interface software platform for all new customer projects of Harris Orthogon since January 2013. The entirely new concept of ODS™ Open Platform allows an open data and programming environment enabling collaborative development with multiple contributors.

    Integrated Orthogon Visualization Suite contains:

    • ODS Toolbox™
    • ODS™ Open Platform
  • Delivering Tangible Benefits to Air Navigation Service Providers and Airports

    • Improves efficiency by enabling harmonized traffic flows, early arrival planning as well as delay absorption, and balancing arrivals with departures (E-AMAN/ AMAN/ DMAN)
    • Increases capacity by optimizing the utilization of terminal and runway resources (AMAN/ DMAN)
    • Improves environmental sustainability: early delay absorption during the en-route flight phase reduces required time in fuel-intensive holding stacks (E-AMAN)
    • Improves predictability and stability by calculating precise target times (E-AMAN/ AMAN/ DMAN)
    • Enables pre-tactical decision making with alternative Airport Operation Plans (AOPs) and an enhanced time horizon for Airport Collaborative Decision Making (DCB)
    • Improves stand usage through dynamic, event-driven optimization algorithm (Stand Optimizer)
    • Development flexibility: architecture ensures lifelong flexibility for constantly changing environments all the time (ODS™ Open Platform)


Demand Capacity Balancer (DCB)

Airport infrastructure is becoming increasingly constrained, more so the Airspace and Airside. New terminals and passenger solutions will not address these Airside constraints. A-CDM went someway to addressing this, but only provided a short look-ahead …

Orthogon Stand Optimizer

Stand Optimizer improves the stand utilization at airports with high traffic volumes and a high deviation from planned flight schedules resulting in increased airport efficiency and increased stand capacity. Aircrafts are assigned to matching airport …

Orthogon Arrival Manager (AMAN)

The Orthogon Arrival Manager’s objective is to manage the flow of arriving aircraft in a way that makes best use of the available Air Traffic Management resources, such as runways and airspace. Orthogon AMAN manages traffic …

Orthogon Departure Manager (DMAN)

The Orthogon Departure Manager (DMAN) provides consistent, optimized planning of the outbound traffic at airports and accordingly optimized target times for flights at the runway and the stands. Major objectives are to efficiently manage the …

Orthogon Extended Arrival Manager (E-AMAN)

The SESAR Extended Arrival Management (E-AMAN) concept allows air traffic controllers to meter traffic into a busy Terminal Manoeuvring Area from far out in the en-route airspace. This is feasible by extending the AMAN operational …

Orthogon ODS™ Open Platform

With the ODS Toolbox™, Harris Orthogon has acquired a worldwide reputation as a specialist for air traffic Controller Working Positions (CWP) development software. Since its market entry in 1994 the ODS Toolbox™ has been accepted …
