National Airspace System Resource (NASR)

To support air traffic control and other aviation activities, it is necessary to collect, collate, validate, store and disseminate aeronautical information for all components of the National Airspace System (NAS). CGH is managing the continuance of operations and maintenance for the existing NAS Resource without disruption of service, and will complete and maintain the NASR/electronic NASR back-up and Recovery plan.

Sector Design Analysis Tool (SDAT)

Airspace specialists use the Sector Design Analysis Tool (SDAT) for airspace sector design-based ontraffic flow as well as the analysis and creation of minimum vector altitude (MVA) and minimum IFR altitude (MIA) charts. As a priority, the team supports and modernizes MVA/MIA and airspace sector design functionality, which utilizes animated traffic replays in 3D.

Aeronautical Common Service (ACS)

CGH provides development support for the implementation of a cyclic ACS prototype that allows demonstration of value through concrete results. The ACS prototype is designed to demonstrate collection of information from multiple sources, integration, and manipulation of information from a single location to disseminate in a way that is meaningful and coherent using a single source.

Aeronautical Surface Screening Evaluation Tool (ASSET)

CGH’s ASSET, a SaaS solution, is built on a cloud platform and provides a one-stop-shop for Aeronautical data. It allows customers like the Irish Aviation Authority (IAA) to collect Obstacle, Aerodrome and Navaid data and provide analysis adhering to eTOD initiatives set forth by the ICAO. This one-stop-shop web and mobile solution includes advanced visual mapping and also provides a service framework using OGC and other international standards like AIXM to provide data services for other IAA and external programs.

Aviation Information Systems (AIS)

Aeronautical Information Systems (AIS) currently uses several small supplemental systems to collect, maintain, and distribute data that are essential for the daily operational management of information supporting the NAS. CGH provides Operations and Maintenance support for current AIS applications, including the provision of system enhancements that ensure accuracy and efficiency.

Airport Geographical Information Systems (AGIS)

AGIS is an advanced GIS system that helps the FAA collect, store and distribute airport and aeronautical data to meet the demands of the Next Generation National Airspace System. The system is built on open data standards, and includes enhanced workflow and tracking capabilities providing automatic validation of all submitted data. CGH developed, implemented, and currently manages the web-based gateway to the existing AGIS application.

Internet Obstacle Evaluation/Airport Airspace Analysis (iOE/AAA)

iOE/AAA was designed, developed and maintained as a SaaS by CGH. This system provides FAA personnel with one system through which they can perform airspace analysis. CGH continues to enhance the capabilities of this advanced GIS system. which includes the capability to submit UAS/COA cases. CGH is also in the process of providing seamless integration with FAA’s ORMS system via a web-service framework, thus eliminating the current manual process.


CGH is re-engineering the FAA’s fee-for-service Overflights system. Overflight fees are applicable to all aircraft operators conducting flights through US-controlled airspace that do not land or depart in the US. Thanks to CGH’s modernization of the FAA’s legacy technology for surveying air traffic movements, the FAA can improve the effectiveness of its Overflight fee collections in the years ahead while providing critical analysis for the FAA.

Electronic Terrain & Obstacle Data (eTOD)

The electronic Terrain and Obstacle Data (eTOD) team publishes both the built and under construction obstructions, and is responsible for collecting, analyzing, validating, maintaining and communicating the state of obstacles for the aviation community. This quality database is essential for the FAA to maintain accurate information for charting and assisting air traffic control.

Certificates of Authorization (COA)

The FAA’s Air Traffic Organization (ATO) Mission Support Services Office is responsible for issuing Certificates of Authorization (COA) for unmanned aircraft systems (UAS) applying to fly in the NAS. CGH provides support to the UAS Group by creating and maintaining an automated application system that allows the proponents to apply for a COA online.

Federal Notice to Airmen (NOTAM) System (FNS)

The objective of the FNS program is to modernize and improve the collection, management, and distribution process that publishes NOTAMs. The new automated system combines civilian and military NOTAMs into a single source to balance diverse customer needs. The FNS is being used in over 900 U.S. airports and is scheduled for nationwide deployment.

TOD-T Workflow Integration into OE/AAA

To validate obstructions, the FAA’s Terrain and Obstacle Data Team (TOD-T) formerly used a suite of disparate storage, workflow management, and mapping systems that included Documentum, ORMS, ArcGIS, and iOE/AAA. CGH enhanced user interfaces, improved data and document management, alleviated processing backlogs, and eliminated redundant data entry activities by creating a unified, streamlined OE/AAA system.
