NPP Mission Data Format Control Book (MDFCB) Released - 12/5/2006

The NASA Direct Readout Laboratory is pleased to announce the release of the NPP Mission Data Format Control Book (MDFCB). This document describes the data formats and contents of the National Polar-Orbiting Operational Environmental Satellite System (NPOESS) Preparatory Project (NPP) satellite mission data, and provides information to identify, distinguish and extract all of the High Rate Data (HRD) mode (direct broadcast) data.

You may access the NPP MDFCB through the Direct Readout Web Portal at:

"Simulcast Viewer" (Version 3.2.4) for Windows Released - 11/21/2006

The NASA Direct Readout Laboratory is pleased to announce the release of the "Simulcast Viewer" (Version 3.2.4) for Windows. This is the viewer from Simulcast Version 3.0, along with visualization enhancements, in a self-installing package. If necessary, it will also install the JRE Version 1.5. We anticipate the release of an updated Simulcast Services package for Windows/Linux in the very near future. Simulcast is a Java-based multi-mission tool that allows users to select and view quicklook instrument data, in real time and with a single viewer. Simulcast is presently being developed under Java 1.5. Enhancements in Version 3.2.4 for Windows include:

Multiple passes from multiple sources (i.e., a combination of spacecraft and ground station) may now be viewed simultaneously on the map layouts
Preferences selected on the options screen are now persistent, so they remain selected after closing and re-launching the application
A video recorder has been added that allows AVI and QuickTime movies to be created containing the contents of the entire Simulcast Viewer window, or just the map or instrument layouts
Passes may now be sorted by time or name
A default visual (true color, gray scale, etc.) may now be selected for new passes being viewed
Playback looping/throttling has been added to provide a variety of playback scenarios (e.g., viewing multiple passes from multiple sources simultaneously)

Construction Record Lister Version 1.01 Released – 11/3/2006

The Direct Readout Laboratory (DRL) is pleased to announce a new release of the "Construction Record Lister" software package (Version 1.01). This Java program displays—in human readable form—the contents of a Production Data Set (PDS) construction record. For Terra and Aqua, the construction record
component of the PDS contains the instrument Level-0 metadata.

You may access this new version on the Direct Readout Web Portal at:

On the Road to NPP – 9/22/2006

The GSFC Direct Readout Laboratory (DRL) is pleased to update the Direct Readout community on the present state of the open source technology suite on the road to the NPOESS Preparatory Project (NPP).

The DRL is developing a Direct Readout technology framework following a Modular Components Approach (MCA) Model. This MCA has many benefits but, foremost, in response to your requests for the NPP era, the DRL will promote platform-independent code, consistent interfaces, and enhanced data product portability. Click here for more information. (We will update this material as it evolves.)

A very important note: We are working closely with the science discipline teams from Land, Ocean, and Atmosphere to bring you standalone versions of Science Processing Algorithms (SPAs).

Status:
The technology suite under development and select Terra/Aqua SPAs are running on the DRL's publicly-accessible computing cluster. At present the NISGS/IPOPP technology suite is producing 10 Level-2 products for every Terra and Aqua pass, 24/7. The new location for accessing products, meta-data (w/product traceability), and ancillaries is:

ftp://is.sci.gsfc.nasa.gov/

RT-STPS Version 3.06 Released – 6/14/2006

The DRL is pleased to announce a new release of the Real-time Software Telemetry Processing System (RT-STPS) (Version 3.06). This version features more robust handling of socket output channels. It includes an interface to the NISGS Status/Event Logging System (NSLS), and NSLS is bundled with the Version 3.06 distribution now available for download. Version 3.06 incorporates Java Service Wrapper (JSW) support to allow the RT-STPS Server to be installed as a system service on both Windows and Linux platforms, and the code has been recompiled under Java Development Kit (JDK) Version 1.5. Lastly, we have provided enhanced installation procedures for both Windows and Linux platforms.

Simulcast Version 3.0 Released – 5/9/2006

The DRL is pleased to announce a new release of the Simulcast toolkit (Version 3.0). Simulcast is a multi-mission tool that allows users to select and view quicklook instrument data, in real time and with a single client. Simulcast is presently being developed under Java 1.5. Enhancements in Version 3.0 include:

Real-time geolocation and pseudo-calibration, and projected on Mercator and Polar map for MODIS
Reorganized Client windows to maximize viewable image area
Auto Day/Night mode to allow passes near a pole to be viewed in TrueColor mode during the day portion, and Infrared mode during the night portion
Satellite orbits predicted (at present: Aqua and Terra) and projected on Mercator and Polar map

Ground Based Attitude Determination (GBAD) Software Version 2.5 Released – 5/2/2006

The DRL is pleased to announce a new release of the Ground Based Attitude Determination (GBAD) processing software (Version 2.5). Version 2.5 incorporates syntax enhancements that previously inhibited compilation using the GCC 3.4.4 Compiler, and includes modifications for execution on both 32-bit and 64-bit Intel-compatible machines. Although consideration was given to rendering this modification machine-independent, we are not able to verify correctness on all platforms.
