Radiation or Radiological Event Detection

ASPECT's Gamma Emergency Mapping (GEM) technology improves the nation’s airborne gamma-screening and mapping capability of ground-based gamma contamination following a wide-area radiological dispersal device (RDD), improvised nuclear detonation (IND), or nuclear power plant (NPP) accidents.
  • Utilizes commercially available state-of-the-art hardware and software
  • Provides the only airborne remote sensing system in the country with a versatile NaI and LaBr crystal detection setup
  • Applies IAEA, DOE, and EPA processing algorithms 
  • Offers near real-time product development based on customer input

Chemical Detection

ASPECT can detect and quantify gaseous constituents present in the air column between the aircraft and the ground using the principles of remote passive infrared detection via a Fourier transform infrared spectrometer (FTS) to detect and quantify gaseous constituents present in the air column between the aircraft and the ground.

ASPECT’s chemical detection software filters out common atmospheric constituents as it automatically searches for 78 chemical compounds, near real-time, in the air column below the aircraft.

Aerial imagery

ASPECT provides first responders with critical situation data in the form of high-resolution aerial images, enhanced with chemical and radiological information and displayed using easy-to-use technology like Google Earth.
  • Available infrared and photographic images with geospatial chemical and radiological information 
  • All imagery is geo-rectified using both aircraft attitude correction (pitch, yaw, and roll) and GPS positional information
  • Georeferenced high resolution oblique images
  • Image processing is composed of two primary steps including image enhancement and geo-registration
  • If requested, aerial photography (and IR imagery) can be stitched into a wide area mosaic
  • All displayed and easily access via Google Earth or a secure FTP site; Google and GIS compatible formats
