Electronics & Software

The Common Access Manager (CAM) software was developed to control access to functions and data for mission control, telemetry, tracking, instrument data, and other ground data system capabilities. The CAM software is used by Advanced Multi-Mission Operations System (AMMOS) and Deep Space Network (DSN) subsystems,...

In high-end computing environments, remote file transfers of very large data sets to and from computational resources are commonplace, as users typically are widely distributed across different organizations and must transfer in data to be processed, and transfer out results for further analysis. Local...

The objective of the LTAS Simulator application is to transmit one or more streams of simulated LTAS data frames in User Datagram Protocol (UDP) packets to the network. Each LTAS data frame is filled with simulated data values, with each data field determined using several methods: 1) constant...

The Inductive Monitoring System (IMS) software uses data mining techniques to automatically characterize nominal system operation by analyzing archived system data. These nominal characterizations are then used to perform near-realtime...

This week’s Question: A PhD student at Eindhoven University of Technology has developed a way of using infrared rays to carry wireless data to a laptop or smartphone. The wireless data comes from central "light antennas" that could, for example, be mounted on a ceiling to direct the rays of...

The Internet Engineering Task Force (IETF) standardized Bundle Protocol (BP) enables data transfer using “bundles” over a Delay/Disruption Tolerant Network (DTN). BPTables is a bundle filtering framework that enables the establishment of barriers between more and less trusted BP network domains, and...

Both the aerospace and automotive industries depend increasingly on electrochemical energy storage. Reduction in mass, increase in energy, and increase in power can benefit both of these areas dramatically. Supercapacitors are currently under consideration for use in both...

Architecture development often is conducted prior to system concept design when there is a need to determine the best-value mix of systems that works collectively in specific scenarios and time frames to accomplish a set of mission area objectives. Conducted prior to Pre-Phase A of the...

An innovation from NASA Glenn Research Center increases the efficiency and versatility of fuel cell stacks for power generation. To meet the requirements of a fuel cell system, engineers have typically added direct-current-to-direct-current (DC-to-DC) converters that reduce the voltage produced at the ends of the fuel...
