Projects and Experience

Projects and Experience


SST has extensive domain knowledge and experience pertaining to the engineering, development and implementation of software solutions specializing in Air Traffic Control (ATC) systems and Air Traffic Management (ATM) technologies. Over the past 14 years, we have gained a comprehensive understanding of the U.S. National Airspace System (NAS) as well as the FAA Next Generation Air Transportation System (NextGen). Our experience encompasses a broad range of activities such as requirements analysis and specification, system and software design, prototyping, development, testing, integration, installation, and documentation for projects involving distributed real-time client/server systems, business process re-engineering, database systems, and human factors.

SST has provided exceptional software engineering services to the Federal Aviation Administration (FAA), National Aeronautics and Space Administration (NASA) and to companies within the Air Traffic Control and Air Traffic Management industry. We have direct experience in the development and implementation of various major FAA programs, particularly the Center TRACON Automation System (CTAS) program and the Traffic Flow Management Modernization (TFM-M) program. We also have deep experience with the Enhanced Traffic Management System (ETMS). A summary of our project history follows:

ICAO Air Navigation Plan Automation Tool (IAAT)

A Web based database application to consolidate the process of amending the Air Navigation Plan (ANP) policies and procedures of the member states while providing a mechanism to analyze international traffic patterns, loads, and structures.

Traffic Flow Management Modernization (TFM-M)

TFM-M is a FAA initiative to modernize the Traffic Flow Management (TFM) Infrastructure which is part of the National Airspace System (NAS) Architecture. The Traffic Flow Management System (TFMS) enhances information sharing and collaborative decision-making by enabling the FAA and NAS users to make collaborative decisions  that optimize the flow of air traffic and minimize the adverse effects of air traffic constraints thus increasing the capacity of the nation’s airspace and reducing costs.

TFMS provides better predictions of when the number of flights exceeds available routes and capacity in specific geographical areas. TFMS uses a Service-Oriented Architecture (SOA) platform based on systems technologies that include a relational database, business process management, business rules engine, XML-based messaging, reporting tools, Web services and portals. TFMS architecture adheres to open industry-driven standards such as the Java 2-Enterprise Edition (J2EE) suite, Linux and XML. It supports interface to the System Wide Information Management (SWIM) enterprise infrastructure services.

Traffic Management Advisor (TMA)

An Air Traffic Management tool that calculates meter fix crossing times for all inbound aircraft to destination runways within air route traffic control center (ARTCC) airspace. It will provide controllers with the capability to develop arrival sequence plans for selected airports and will assign aircraft to runways to optimize airport capacity.

Multi-Center Traffic Management Advisor (McTMA)

An extension of the TMA which only works at airports that are within a single center (ARTCC) of control. McTMA provides interfaces between different instances of TMA.

Direct-To (D2)

D2 is a decision support tool that is part of NASA's Center TRACON Automation System (CTAS) tool suite. It was designed to help air traffic controllers search for alternatives of flight plans to shorten the flying time of a commercial flight from its original plan without causing any side effects such as unsafe aircraft separation or increased controller workload. It advises the controllers on direct, time-saving routes for any aircraft and whether there will be conflicts with other aircraft along the new shorter flight path. The end result is to save travelers many hours of unnecessary delays.

Conflict Prediction and Trial Planning (CPTP)

CPTP is a decision support tool that is part of NASA's Center TRACON Automation System (CTAS) tool suite. It uses the trajectory synthesis capability of CTAS to generate predicted route trajectories for the conflict search and trial planning processes. It provides air traffic controllers with a conflict list of the aircraft pairs predicted to be in conflict and a graphical representation of conflict geometry.

Departure Sequencing Program (DSP)

An Air Traffic Management tool that coordinates departures from multiple airports, to optimize airport departure throughput, and to minimize airport delays.

Surface Management System (SMS)

SMS is a NASA Ames Research Center's Advanced Air Transportation Technologies (AATT) project. NASA, in cooperation with the FAA, is studying automation for aiding surface traffic management at major airport facilities. SMS is an enhanced decision support tool that will help controllers and airlines manage aircraft surface traffic at busy airports, thus improving safety, capacity, efficiency and flexibility. SST is developing capability for SMS to query public airport and airline websites for gate assignments and departure/arrival times. These connections allow SMS to be run with proprietary airline connections.

CTAS Analysis and Builder (CAB)

CAB provides a complete environment for creating and maintaining the adaptation of the Center TRACON Automation System (CTAS) software system for a specific site. CAB provides the capability to develop baseline adaptation and to automatically update the adaptation on the Chart Change Updates (CCU). Additionally, CAB allows the user to analyze and evaluate the CTAS system in post operation analysis and near time operation analysis.

System Wide Evaluation and Planning Tool (SWEPT)

SWEPT is an air traffic flow management (TFM) decision support tool that is used by air traffic management specialists at the national or regional level. The SWEPT conformance monitoring application provides air traffic management specialists with a tool to monitor the execution and success of various TFM initiatives. Graphical displays provide the capability to monitor the progress of individual flights that are being impacted by current restrictions. SWEPT can be used either in real-time or for post-operations analysis. For each active and proposed aircraft in the National Airspace System (NAS), the SWEPT trajectory prediction module can predict demand at sectors, fixes and airports. Graphical displays are available to quickly identify NAS resources that are over-utilized. The rerouting, miles-in-trail (MIT) and ground delay program (GDP) algorithms in SWEPT can be used in conjunction with the trajectory prediction module to rapidly assess the impact of a TFM restriction prior to implementation. The goal of SWEPT is to provide the capability to allow traffic management specialists to determine the effectiveness of various TFM initiatives in a pro-active manner.
