Software for Lossless Data Compression

Lossless data compression has been employed in space to reduce communication bandwidth requirements for onboard storage for more than 15 years. A widely used space compression standard is the recommendation published by the Consultative Committee on Space Data Systems (CCSDS). The standard describes a simple, efficient, lossless compression scheme that can be applied to data generated from various space instruments such as radiometers, gamma ray detectors, and optical sensors.

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.

Software for Executing International Standard CCSDS 123B

Advanced remote-sensing instruments in recent years often employ multiple wavelengths for maximal science return. Many of them comprise hundreds to over a thousand spectral bands. These instruments multiply the data volume and stress the communication bandwidth. With previously deployed space lossless data compression standards only applicable to individual bands, a need exists to further improve performance by using spectral information.

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.

Module::Build::Database

Module::Build::Database was developed as part of the Atmospheric Composition Processing System, which works with the Science Investigator-Led Processing System for the Ozone Monitoring Instrument. The technology allows the user to distribute changes to the schema in a database alongside software that relies on the database.

Big Ideas for Small Spaces

Over 24 hours from April 4 to 5, six top French design studios conceived and presented new product concepts for urban environments during the Small Spaces Design Hackathon, presented by Cut&Paste in partnership with Hewlett-Packard. In dense city neighborhoods, homes are small and office space is at a premium, so urban dwellers must be more creative in how they use their space. The design concepts were presented at Cyclone Le Studio as part of ZED, HP’s creative popup space.

Remote Sensing Moisture Model Could Aid Farmers

Global farmers could get better decision-making help as refinements are made to North Alabama soil moisture modeling research being done by an atmospheric science doctoral student at The University of Alabama in Huntsville. The models indicate how much added moisture would be needed in a given area versus historical data to achieve various crop yields, and they could aid in making expensive infrastructure investments by helping to determine their economic viability.
