Sensors/​Data Acquisition

A sensor element that consists of a thermally resistive layer made of nand p-type semiconductor elements amplifies the temperature gradient in the resistive layer that results from heat flow through the sensor. The thermoelectric array provides greater accuracy and sensitivity over a traditional thermopile arrangement for...

A Web interface framework has been developed that implements the Open Geospatial Consortium (OGC) Sensor Planning Service (SPS) specification. The OGC defines the SPS to “provide information concerning content and encoding of the parameter data that has to be provided in order to...

Traditionally, sensor systems are considered independent systems that are separately designed, manufactured, and integrated into a target system such as an aircraft. In most cases, this is a complex and costly process including sensor design, installation, wiring, testing, and maintenance. The sensor...

One way of imaging exoplanets around nearby stars is to use a starshade in conjunction with a space telescope. Typically, the starshade, which resembles a sunflower in outline, is ~ 30 meters in diameter. The starshade is flown about 50,000 km in front of the telescope, and when positioned...

Remote sensing — the use of spacebased satellite technologies to obtain information on environmental variables — in combination with other types of data, can provide information on changes in the Earth’s surface and atmosphere that are critical for weather forecasting and responding to human...

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...

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...

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...

The Hyperlinked Overview of Piloted Evaluations (HOPE) application provides an interface for users to enter data on pilots, metrics, configurations, tasks, and data collection sessions, as well as descriptive information for each item and the experiment as a whole. As this...

Satellite Situation Update (SSUP) software shows the current locations of a selected set of orbiting spacecraft, along with each satellite’s ground track and/or orbit shape. SSUP is intended as a real-time display, showing multiple spacecraft, that is suitable for a large wall monitor meant to be in public spaces for...

In testing hydrogen-fueled engines, the purity of the hydrogen fuel is important. Hydrogen may become contaminated with nitrogen (N2), argon (Ar), or oxygen (O2), thereby making the hydrogen unusable for engine testing at Stennis Space Center (SSC). Therefore, for...

This innovation is a sensor technology that can detect pressures, such as ground force reactions, down to 30 g in weight with a minimum resolution of 5 × 5 mm (resolution dictated by the limitations of the resistor grid array). This device uses a commercially available resistor grid array and custom...

Current spacesuit gloves used by astronauts on the International Space Station (ISS) have sustained cuts during extravehicular activities (EVAs) due to sharp edges and burrs, possibly on damaged ISS handrails. A warning system in the glove would aid in identifying the location of sharp objects and the...

A nanostructure-based mechanism was developed for sensing the presence of, and estimating concentration values of, specified chemical components in a sample gas to which the mechanism is exposed, where the concentrations may be as low as five parts per billion. The mechanism receives a...

The planar Microwave Kinetic Inductance Detector (MKID) is very compact and allows a large number of detectors to be fabricated simultaneously and implemented in a focal plane of a telescope using a minimal number of wiring interfaces. In this detector, the incident power is guided...
