HERSCHEL/PACS on-board reduction flight software
SPIE Proceedings, 2008PACS, the Photodetector Array Camera and Spectrometer for the HERSCHEL Space Observatory (HSO) has a sophisticated on-board software performing data reduction and compression to reach a datarate that is compatible with the downlink requirements. For this purpose, highly specialized lossy and lossless techniques are combined to retain a maximum of ...

Software metrics validation: Space Shuttle flight software example
Annals of Software Engineering, 1995Software quality metrics have potential for helping to ensure the quality of software on large projects such as theSpace Shuttle flight software. It is feasible to validate metrics for the purpose of controlling and predicting software quality during design by validating metrics against a quality factor.

Introduction to Flight Software Systems
2017The most straightforward definition of 'flight software' is the complete set of computer instructions running on every processor on the spacecraft. Armed with a better understanding of the logical functions covered by flight software, the definition of flight software is concluded by discussing the engineering artifacts produced by a flight software ...

Experiences in Improving Flight Software Development Processes
IEEE Software, 2009In 2001, the Jet Propulsion Laboratory (JPL) initiated a software process improvement effort. In 2004, JPL began the Multimission System Architecture Platform (MSAP) project and designated it as part of this effort. In 2007, JPL's Engineering and Science Directorate, which controls the MSAP project's technical development, achieved CMMI Staged Maturity

V&V of flight and mission-critical software
IEEE Software, 1989The use of software verification and validation to assure the safety of flight control systems is described. The process considered is performed by the system's developers, not by a separate group as is typical, and it examines the software as part of the system, with emphasis on techniques for review, simulation, and integration and system testing ...

Accelerated application development for flight software
10th Computing in Aerospace Conference, 1995In order to meet the customer need for 'faster, better, cheaper' flight software, a new development method and process were required for the DC-X re-usable rocket demonstrator. The common environment for algorithm design, simulation, code generation and real time testing kept the designer in the process throughout the development cycle.

NASA Study on Flight Software Complexity
AIAA Infotech@Aerospace Conference, 2009*In 2007 the NASA Office of Chief Engineer commissioned a multi-center study to bring forth technical and managerial strategies to address risks from growth in size and complexity of flight software in NASA’s space missions. The motivation for the study grew from problems attributed to flight software in a variety of missions—in both pre-launch and ...
