SOLUTION Honeywell selected EXB to contribute to the development and delivery of the CASS-IDTS to the Navy. In this project EXB: 

•  Participated in the development of the of system architecture, developed software and integrated the ship’s navigation estimate with the IDTS internal reference unit.

•  Developed internal diagnostics for the IDTS.

CHALLENGE The US Navy’s carrier fleet requires the automated testing of Inertial Measurement Units (IMUs) and Inertial Reference Units (IRUs) aboard ships which use inertial equipment. Honeywell provides the Inertial Device Testing System (IDTS) as a component of the Consolidated Automated Support System (CASS) to enable this capability.   In order to meet the Navy’s requirements, Honeywell developed a land-based version of the system. The system uses its own dedicated inertial reference unit in combination with the ship’s navigation system as a baseline against which other shipboard inertial devices are compared.

NAVY NAVIGATION SYSTEM TESTER

•  Provided analysis of performance problems (communication delays) in the ship’s Navigation Sensor System Interface (NAVSSI) and developed software for the IDTS to resolve these issues.

•  Provided upgrade of Inertial Test Reference System software for Navigation Critical Distribution System compatibility.

•  Assisted in development of contract deliverables including Prime Item Development Specification, Software User’s Manual, and Users Guide for Test Program Set Development.

Together Honeywell and EXB developed the IDTS software in a Windows environment using MATLAB, C++ and over 16,000 lines of code. The system was evaluated in a Lab VIEW environment. The team successfully delivered the system to the Navy and provided delivery support including shipboard visits to integrate the IDTS with the carrier based systems, and sea trials.

CRITICAL AEROSPACE SYSTEMS

CHALLENGE Honeywell is one of the world’s largest suppliers of aircraft avionics and aerospace infrastructure components. They provide numerous safety-critical systems for navigation and guidance systems and sensors, aircraft controllers and aircraft landing infrastructure. These Honeywell systems and sensors require DO-178B/C Level A software development and verification. In addition to the initial process, retesting due to software changes is extremely time consuming and expensive.

SOLUTION Honeywell has identified EXB as a preferred supplier and selects EXB to support system requirements review and system verification for numerous safety-critical products. A few of the major projects that EXB has successfully completed with Honeywell include:

•  Boeing 787 Flight Control System Testing •  Airbus A380 Air Data/Inertial Reference Development and Test

•  NASA Space Shuttle Main Engine Controller System Audit •  FAA/ICAO Approved Ground Based Aircraft Landing System Development

Testing

•  GG1320AN2x Laser Gyro Software Verification

EXB applies our verification methodology in concert with Honeywell’s FAA certification processes to safety-critical software development projects. In many applications EXB uses our TestCompass® toolset to automate the process reducing the schedule impact of requirement changes and reducing certification costs.

EXB demonstrated the capability of the TestCompass® toolset by completing low-level testing in ½ the time documented in Honeywell’s plan. In the same evaluation quality increased through the execution of 1.1 million test points and weekly automated regression testing. EXB advanced from 20% to 5% technical oversight for percentage DO-178B Level A project work. EXB’s 5% oversight represents the lowest for a Honeywell supplier on a software verification project.

SOLUTION Honeywell selected EXB to contribute to the development and testing of the Core Computer Software Configuration Item Flight Software for the Orion Crew Exploration Vehicle. Activities EXB performed for the customer included:

•  Creating, electronically reviewing, compiling, executing, and delivering

thread level requirements-based and structural coverage test cases for all Software Requirements Document (SRD) requirements.

•  Resolving issues with the test environment. •  Participating in auditing activities conducted by customers and Honeywell

Software Quality Assurance. 

EXB performed to Honeywell’s CMMI Level 5 compliant FSW Core Standards and Processes. Project planning, scheduling, and status reporting were provided by EXB, including earned value metrics. For this project EXB used its automated verification methodology for Requirements�Based Testing and its TestCompass® toolset. The methodology increased quality and reduced execution time and cost. Test cases and executable test procedures were automatically generated and executed in a fully integrated test development and execution environment. EXB’s automated test procedure generator was integrated with Honeywell's proprietary test environment, saving an average of two hours of development time for each test of approximately 450 tests.

NASA ORION FLIGHT SOFTWARE

CHALLENGE NASA is developing the Orion spacecraft to carry crews to Low Earth Orbit (LEO) and beyond. The Orion capsule will provide deep space travel and earth re-entry and the capability to conduct regular in�space operations, including rendezvous docking and extra�vehicular activity. The first flight of the Orion space craft will demonstrate an emergency abort. Honeywell is responsible for providing the Core Flight Computer for Orion to Lockheed Martin and NASA. The embedded software for the Orion Core Flight Computer is safety critical and NASA man rated category A.

SOLUTION Lockheed Martin selected EXB to support staffing on a number of programs critical to the US National Air Space (NAS) including: •  CARTS (Common Automated Radar Terminal System), is an air traffic control

computer system that air traffic controllers use to track aircrafts. The computer system automates the air traffic controllers job by correlating radar and human inputs. This system is used in most of the TRACONs (Terminal Radar Approach Controls) in the NAS.

•  MEARTS (Microprocessor En Route Automated Radar Tracking System) combines both en route and terminal air traffic control functions. It provides single-sensor and multiple-sensor mosaic derived situation displays of air traffic data received from FAA and Defense Department long-range and short-range radars. Micro-EARTS is installed in ten FAA and Defense Department locations. 

•  ERAM (En Route Automation Modernization) is an FAA Air Traffic Control system designed to provide faster processing of route requests and in-flight route changes. ERAM system architecture replaces the En Route Host computer system and its backup. New capabilities to improve information security and streamline traffic flow at international borders support the evolution of the National Airspace System (NAS). ERAM processes flight radar data, generates display data to air traffic controllers, provides communication support, and detects and alerts air traffic controllers when aircraft are flying together for safety and long term planning.

EXB is a preferred staffing supplier to Lockheed Martin, providing skilled critical resources at required locations. EXB resources continuously demonstrate their ability to resolve the needs of the infrastructure support and development programs. EXB is SDVOSB certified and regularly demonstrates access to experienced systems and software talent.
