Flight Processor Virtualization for Size, Weight, and Power Reduction

A flight software system that was originally deployed on six separate physical processors is modeled using a single processor.

Goddard Space Flight Center, Greenbelt, Maryland

This work demonstrated the cost-saving and fault-tolerant benefits of virtualization technology by consolidating the flight software from multiple flight processors into a single virtualized system. In this study, a flight software system that was originally deployed on six separate physical processors was modeled using a single processor and a real-time embedded hypervisor.

Gridded Atmosphere Products from GPS Radio Occultation Measurements with Bayesian Interpolation Technique

GPS radio occultation measurements are vital for climate monitoring and atmospheric temperature change detection. However, the data are irregularly distributed in space and time, which makes it inconvenient for many applications.

Goddard Mission Services Evolution Center Compliance Test Suite

To reduce the cost of building specialized interfaces, missions can adopt Goddard Mission Services Evolution Center (GMSEC) technologies and applications. Assurances need to be made that application implementation should follow the GMSEC messaging standards. The GMSEC Interface Specification Document (ISD) sets forth definitions for all GMSEC message types.

NASA Experiment Designer: A Tool for Running Scientific Workflows

The NASA Experiment Designer (NED) is a client-server application that enables end-to-end support for driving long-running scientific computer simulations such as climate and weather models. The tool provides a friendly, single point of entry for configuring parameters associated with the workflow for model experiments and related preprocessing/postprocessing tasks.

Asynchronous Message Service (AMS) Software Libraries

This software implements the protocols described in the Consultative Committee for Space Data Systems (CCSDS) publication CCSDS 735.1-B-1. The purpose of the protocols is to enable the exchange of messages among a group of applications. The protocols provide several mechanisms for message exchange, including publish/subscribe (i.e., the source of a message specifies a subject, and the message is delivered to all members who have subscribed to that subject) and direct send (i.e., the source of a message specifies a particular member for whom to deliver the message). One of the protocols (Meta-AMS) supports a local community of applications. Another protocol (Remote-AMS) provides a gateway mechanism that connects multiple local message communities together, enabling a publish/subscribe capability between communities that, for example, might be on different planets.

TASAR and TAP: Airborne Trajectory Management Enabled by Traffic-Aware Software

This innovation consists of the Traffic Aware Strategic Aircrew Request (TASAR) concept and the associated Traffic Aware Planner (TAP) software. TASAR is intended to enable pilots to discover trajectory improvement opportunities while en route that will result in immediate operational benefits for the airspace user and be approvable by Air Traffic Control (ATC). TAP is a cockpit-based advisory tool that enables the TASAR concept, and it was developed to be hosted on a Class 2 Electronic Flight Bag. This near-term concept provides pilots with a strategic re-planning capability that optimizes fuel burn or flight time; avoids interactions with known traffic, weather, and restricted airspace; and may be used by the pilots to request a trajectory change from ATC with increased likelihood of approval. TAP’s internal architecture and algorithms are derived from the Autonomous Operations Planner (AOP), a flight-deck automation system developed by NASA to support research into aircraft self-separation.

Weekly Status Reporting & Approval Application Revision 2

The Weekly Status Reporting & Approval Application is a Web application that enables organizations to gather weekly or monthly (periodically) statuses electronically from all employees using a time-based process. Users input their status, which may include uploaded images, into previously agreed-to categories. The system provides an approval process that allows for forwarding of statuses up the organizational hierarchy by designated approvers. Approved statuses get put into a final downloadable report. Historical statuses can be downloaded in report form to get a year at a glance for individuals and groups.

CoolSPICE: SPICE Simulator for Cryogenic Electronics

Accurate assessment of circuits at cold temperatures is extremely difficult due to lack of models and tools that can simulate circuit behavior at cryogenic temperatures. A library of cryogenic temperature models was built, as well as a circuit simulator that can use those models and simulate complex circuits at temperatures as low as 4 K.

Convex Hull-Based Plume and Anomaly Detection

A number of deep space missions have imaged plumes at Io, Enceladus, and other smaller bodies. These phenomena provide valuable information regarding these bodies. To date, this imagery has been captured fortuitously. The ability to utilize onboard processing to conduct campaigns capturing large numbers of images and to detect when a plume event is occurring would open up new mission paradigms. Extended temporal campaigns could provide comprehensive detail on these events’ frequency and character.

Software for Non-Contact Measurement of an Individual’s Heart Rate Using a Common Camera

A software application detects the heart rate of an individual by using a real-time video stream from a common camera connected to their computer. This involves no contact between the user and the camera, or calibration between individual users. NASA’s OpenMDAO framework was used to implement and coordinate the necessary data acquisition and signal processing functions.
