|Our products are utilized in a wide range of applications. Some of the projects
- Visible/Infrared Imager Radiometer Suite (VIIRS). The VIIRS cross-track sensor
measures reflected sunlight to help civil and military organization better understand environmental and meteorological processes
through space-based, remotely sensed environmental data: meteorological, oceanographic, climatic and space. VIIRS will measure
reflected sunlight in spectral bands within the visible-to-thermal infrared range and will track cloud cover, ocean surface
temperature and sea ice across the planet to enhance both short and long term weather forecasting.
- Visible/Infrared Spin Scan-Radiometer (VISSR). VISSR tracks cloud motion to supply
storm warning and global atmospheric circulation data. It provides high-resolution images of Earth and its cloud cover every 30
minutes, acquiring imagery as it spins west to east at 100 rpm aboard a spin-stabilized spacecraft, step scanning north to south
on each spin to provide cloud imagery and data for determining cloud and surface temperatures and wind fields.
- Moderate Resolution Imaging Spectroradiometer (MODIS). MODIS is the key instrument
aboard NASA's Earth Observing System satellite. It views Earth's entire surface every one to two days, acquiring date in 36
spectral bands-from visible to long-wave infrared-making a detailed understanding of global ecosystems and their relationship to
one another and allowing scientists and policy-makers to develop appropriate environmental protection policies. Gathering data
on surface temperature, ocean color, concentration of chlorophyll, vegetation and land surface cover conditions, cloud and
aerosol properties, total atmospheric water vapor and total ozone measurements, MODIS is a key part of NASA's "Mission to
Planet Earth" program.
- Sea-Viewing Wide-Field-of-View Sensor (SeaWiFS). Part of NASA's "Mission to
Planet Earth" Program, SeaWiFS records the levels of radiance reflected from the ocean in the visible wavelength which is
used in oceanographic research, the fishing industry, marine transportation and offshore oil and gas exploration and
- Enhanced Thematic Mapper Plus (ETM+). ETM+ is a passive sensor aboard Landsat-7
that measures the solar radiation emitted and reflected by the Earth. Because of Landsat's importance in providing accurate
measurements, increased emphasis has been placed on ETM+'s calibration accuracy: three independent onboard calibration systems
calibrate the panchromatic visible and near infrared (VNIR) and short wave infrared (SWIR) bands. The radiometric accuracy
achieved is 5% absolute (2% relative).
- Space Based Infrared System Low (SBIRS Low). SBIRS Low will provide precise
midcourse tracking and discrimination of objects in support of the SBIRS missile defense mission. This Low-Earth orbiting
component of the SBIRS architecture's mission is global coverage for national security and supporting the war fighter. SBIRS Low
will have the unique capability of tracking missiles from launch to reentry and will relay necessary cueing date to missile
interceptors before a missile warhead reaches friendly territory or forces. It also supports missile warning, technical
intelligence gathering and battlespace characterization missions.
- Miniature Thermal Emission Spectrometer (Mini-Tes). Based on the Mars Global
Surveyor, Mini-TES is providing micro-spacecraft, surface lander and rover missions with thermophysical data. It is suitable for
flyby, orbital, low-altitude or surface study missions, and separates the fore-optics, spectrometer and electronics into
mission-configurable modules. It addresses geologic and atmospheric science objectives by measuring mineralogical and physical
properties, aerosol, condensate, gas, pressure and temperature. It could support more detailed Martian atmospheric and surface
examination, and its instruments could examine features as small as a centimeter. Low-altitude aircraft or balloons could
provide MDG-data-guided site survey with low mass and power instrumentation followed by surface examination of specific minerals
and rocks and surface-based atmospheric measurements.
- Next Generation Space Telescope (NGST). NGST is anticipated to be 10 times more
powerful, able to detect radiation from sources 400 times more faint than those seen by the Hubble Space Telescope and able to
see light emitted from distant galaxies as they were 10 billion or more years ago, back to the creation of the first stars and
galaxies. It will also search for new stars and planets forming in the Milky Way that emit large amounts of infrared radiation
but no visible light. Although only in the planning stages, it is anticipated to fend off the menace of heat from the Sun that
diminishes the effectiveness of infrared detectors by orbiting a million miles from Earth and deploying a huge shield to block
radiation; and to operate at temperatures of only 50 degrees above absolute zero. Rather than a replacement for Hubble, its
mission will be to answer questions Hubble and other telescopes cannot with regard to the shape of the universe, how galaxies
are formed, and the nature of dark matter--which is postulated to exist but never detected.
- Ground-based Midcourse Defense Segment Exoatmospheric Kill Vehicle (EKV). The EKV
is the intercept component of the Ground Based Interceptor whose mission is to protect against a small-scale missile attack by
colliding with an incoming warhead and completely pulverizing it. This collision ensures complete destruction of a warhead
carrying weapons of mass destruction—nuclear, biological or chemical and the means of delivery, such as mid-range and
long-range ballistic missiles in the midcourse or exoatmospheric phase of their trajectories.
- Advanced Targeting Forward-Looking Infrared (ATFLIR). ATFLIR features
state-of-the-art third generation mid-wave infrared targeting and navigation FLIRs, and electro-optical sensor, laser
rangefinder and target designator and laser spot tracker, which extends the target detection and recognition range of the F/A-18
aircraft. The navigation laser spot tracker and targeting FLIR functions on today’s F/A-18 aircraft are provided by 3 separate
pods. In the ATFLIR, the navigation FLIR function is integrated into the adapter that connects the pod to the aircraft. The
targeting FLIR and laser spot tracker are integrated into the pod. ATFLIR is a member of the Terminator family of
infrared targeting pods.
- Infrared Acquisition and Designation Systems (IRADS). The IRADS is the
electro-optical targeting system for the U.S. Air Force’s F-117A Stealth Fighter. It combines infrared imaging and laser
designation for precision weapon delivery.
- Astronomical Large Area Detector Development on InSb (ALADDIN). The secrets of the
universe continue to be unlocked by the use of infrared focal plane arrays in astronomical instruments and astronomical
observations are now achievable fro the near-infrared to long wavelength regions. ALADDIN provided the first large format MWIR
arrays that contain more than one million detector elements and was designed specifically for low backgrounds with high quantum
efficiency, low noise, low dark current and high operability. Now able to probe deep through the dust and gas, the infrared
probes through the dense clouds revealing many young stars in formation totally invisible in the visible spectrum.
