Spectra View Oblique

5 Color Cameras

• 4872 x 3248 pixels
• Dynamic Range 12 bit
• 1 camera Nadir, 1 camera left, 1 camera right
• 1 camera forward, 1 camera aft.
• All oblique cameras at 45 degrees to line of flight

Shutter

• Electronic 1/100 - 1/1000 (No moving parts, no life limits)

Light Metering

• Images are viewed in flight. Exposure times are set by the operator from histograms for each camera. Remote controlled aperture.

Calibration

• Each camera/lens combination is totally mapped for radial distortion, PP, MTF, and Flat Field using Airborne Data System's propietary CHARLIE® Calibration System.

• All optics are Carl Zeiss
• 153 degree FOV cross track (custom optics available)
• 71 degree FOV along track (custom optics available)
• Variable Optics for constant resolution.
• Nominal Resolution: 4 inch @ 150 Kts.

RF/EMI Certification

• This system meets both civilian and US Air Force requirements for RF/EMI emissions and is certified for operation in small, medium and large US Air Force fixed wing aircraft.

All cameras are co-mounted with the DGPS/INS in precision machined fixture. Band registration and DGPS/INS alignment is accomplished using Band-Match software. All systems use Lord Aerospace vibration isolating mounts that have been tested to meet Section RTCA/DO-160 Section 7.

Custom mounting decks are available

Flight Planning Software (FPS)

• Plans flight lines and image centers from shape file or corner coordinates. Calculates image center positions to include side and forward overlap. Calculates number of scenes and mission time. Provide a visual display. Automatically recalculates flight lines and image centers in flight to provide full coverage in changing altitudes.

Spectra View Remote

• Provides link between the Spectra-View camera system and the System Operator. Provides visual display of the health of the DGPS/INS, cameras, processor and image storage system at start up. Allows System Operator to set shutter speeds and aperture settings to maintain highest quality data for the flight conditions. Displays the camera information in visual quality and histogram format for each camera and respective band.

Course Deviation Indicator (CDI)

• Displays the precise position of the aircraft in relation to flight line. Displays proposed and actual heading, altitude, speed, flight line number and beginning and ending waypoints.

Band Match Oblique

• Ties NADIR, left and right cameras together to Ortho-Rectfy image.
• Matches Forward and Aft Scene to NADIR Scene.
• Uses imported DEM files, image and header files to automatically Ortho-Rectify images.
• Exports processed images to assigned files.
• Exports header files in NITIF format.
• All processing is done in real time, from navigation solutions stored in header file.
