TL;DR: The Laser Ranging Interferometer (LRI) instrument on the GRACE Follow-On mission has provided the first laser interferometric range measurements between remote spacecraft, separated by approximately 220 km.
Proceedings ArticleDOI
Programming with non-heap memory in the real time specification for Java
Greg Bollella,Tim Canham,Vanessa Carson,Virgil Champlin,D. Dvorak,Brian Giovannoni,Mark Indictor,Kenny Meyer,Alex Murray,Kirk Reinholtz +9 more
TL;DR: The issues of programming with non-heap memory from a practitioner's view in designing and programming real-time control loops using a commercially available implementation of the RTSJ is explored.
Proceedings ArticleDOI
OO techniques applied to a real-time, embedded, spaceborne application
Alex Murray,Mohammad Shahabuddin +1 more
TL;DR: It is found that OOA and OOD with UML actually enhance communication with systems and hardware engineers and that C++, thoughtfully used, need not lead to code bloat, and that its performance is every bit as good as that of C.
Proceedings ArticleDOI
Toward a model-based approach to flight system fault protection
TL;DR: This paper begins with an overview of the FP domain, and then continues with a presentation of a SysML/UML model of theFP domain and the particular analyses that it contains, by way of showing a potential model-based approach to flight system fault protection, and an exposition of the use ofThe FP models in FSW engineering.
Proceedings ArticleDOI
A UML profile for State Analysis
Alex Murray,Robert Rasmussen +1 more
TL;DR: State Analysis is a systems engineering methodology for the specification and design of control systems, developed at the Jet Propulsion Laboratory, that emphasizes an analysis of the system under control in terms of States.
