ATMS Antenna Beam Analysis Software

Goddard Space Flight Center, Greenbelt, Maryland The Advanced Technology Microwave Sounder (ATMS) Antenna Beam Analysis Software uses a suite of test data to calculate the ATMS instrument beam pointing, and secondarily, the polarization state, in the coordinates of the onboard optical cube. The software uses measurement inputs of RF radiation pattern performance made at multiple rotational viewpoints and across a range of frequencies, rotation matrices to characterize physical rotation between the instrument measurement states and the optical cube, and correction rotation matrices used to eliminate gravity effects through an independent characterization.

LabNotes Mobile App for Instrument Control and Data Collection

This application greatly reduces the cost and size of data acquisition components. Goddard Space Flight Center, Greenbelt, Maryland Most instruments under development rely on a traditional computer or laptop, LabVIEW software, and data acquisition (DAQ) components (which interface between the instrument and the computer) to operate an instrument and collect data. While this solution is extremely versatile, it is an overly complicated, bulky, and expensive solution to relatively simple problems such as sending commands to a laser controller or recording voltages.

GRAVITE Incinerator

Goddard Space Flight Center, Greenbelt, Maryland Government Resource for Algorithm Verification, Independent Test, and Evaluation (GRAVITE) system is a National Oceanic and Atmospheric Administration (NOAA) system, developed and deployed by Joint Polar Satellite System (JPSS) Ground Project to support Calibration and Validation (Cal/Val), Data Quality Monitoring, and Algorithm Investigation, Tuning and Integration. GRAVITE enables novice and expert users to discover and obtain data easily by using standard protocols. The Incinerator is a component of the GRAVITE version 3.0 (GV3.0) system. It is responsible for system maintenance tasks and deletes expired files, expired subscription links, expired PGE execution directories, and generates statistics periodically.

GRAVITE Distribution

Goddard Space Flight Center, Greenbelt, Maryland Government Resource for Algorithm Verification, Independent Test, and Evaluation (GRAVITE) system is a National Oceanic and Atmospheric Administration (NOAA) system, developed and deployed by Joint Polar Satellite System (JPSS) Ground Project to support Calibration and Validation (Cal/Val), Data Quality Monitoring, and Algorithm Investigation, Tuning and Integration. GRAVITE enables novice and expert users to discover and obtain data easily by using standard protocols. GRAVITE version 3.0 (GV3.0) distribution system is a major upgrade to the GRAVITE version 2.0 (GV2.0) distribution tools. GV2.0 enabled users to easily define dynamic searches, which unfortunately resulted in slowing down the operational database, as no back-end validation was performed.

SMAP SDS Science Processing and Data Management System

NASA’s Jet Propulsion Laboratory, Pasadena, California The Science Processing and Data Management (SPDM) system’s primary functions are to control and monitor science processes and data products for Soil Moisture Active Passive (SMAP) Science Data System (SDS). SPDM adapts the Apache/OODT Framework 0.3 as the basic infrastructure. Although the OODT core framework is software-extensible, it provides limited, minimal, and rough functionalities. The adaptation effort has been extensive to fulfill SMAP SDS requirements including the integration of 26 processors with complex interactions among processors and files (≈70 static ancillary data types and ≈30 external dynamic ancillary types), pipeline automation to generate multiple products (LO-3) with large data volumes within a few hours to a few days of radar and radiometer instrument acquisition, monitoring and control of the data system, and interfacing with two NASA Data Active Archive Centers (DAACs).
