NARSS BEECHCRAFT SUPERKING-200 aircraft

NARSS BEECHCRAFT superking-200 aircraft is a twin turboprops aircraft. The engines are manufactured by Pratt & Whitney of Canada. The maximum cruise speed of the aircraft is 535 km/h with max range of 3.334 km and a certified ceiling of 10.668 meters. The wingspan is 16.61 meter, the max airplane length is 13.36 meter, and the max tail height 4.52 meters. The internal cabin dimensions are (LxWxH = 5.08x1.37x1.45m).
The airplane is equipped with an IGI navigation system with Omni-star support to obtain high accuracy of the scanned laser measurements and to minimize the possibility of having gaps between scanned flight strips. The swath of a scanned laser strip ranges from 140 to 280 meters at flight altitudes of 600 to 1200 meters.
The aircraft is equipped with two cameras:

  • ZEISS-RMK-TOP-15 aerial photography camera. This camera uses Kodak roll films of width 9.5” (23.75 cm).
  • TOPOSYS airborne laser scanning system. The system has a Falcon II laser scanner and an accompanying TOPOSYS digital camera.

NARSS Receiving Station at Aswan

NARSS receiving station has been installed at Aswan in Upper Egypt (1000 Km south of Cairo), Egypt. The station is manufactured and installed by the American company (L3-Datron Titan) and is designed to receive images from the American satellite (Landsat), the French satellite (Spot-4) and the European radar satellite (ERS). The station is being upgraded to receive the downlink from the Egyptian satellite (Egyptsat-1).The position of the station is located at Aswan to cover entire Egypt, the Nile basin, most Arabian countries, most Africa and south Europe. The station consists of two parts; one at Aswan for receiving the images in raw format and the other at Cairo for archiving and processing of the data in standard levels.
Products:

  • Spot multispectral 20 meter resolution .
  • Spot panchromatic 10 meter resolution .
  • Spot stereo pair 10 meter resolution

TOPOSYS LIDAR SCANNING SYSTEM

NARSS BEECHCRAFT superking-200 aircraft is equipped with a TOPOSYS airborne laser scanning system. The system has a Falcon II laser scanner and an accompanying TOPOSYS digital camera. The laser scanner-digital camera system uses differential GPS and INS (inertial navigation system) and performs GPS/INS measured data fusion by applying to APPLANIX navigation software to improve the accuracy of the laser scanner measurements.
The airplane is equipped with an IGI navigation system with Omni-star support to obtain high accuracy of the scanned laser measurements and to minimize the possibility of having gaps between scanned flight strips. The swath of a scanned laser strip ranges from 140 to 280 meters at flight altitudes of 600 to 1200 meters.
The TOPOSYS system on the BEECHCRAFT conducts 5 elevation measurements per square meters. This provides a digital surface model (DSM) that includes man-made features and vegetation superimposed on the terrain with 1 meter resolution. The system measurement accuracy is 15 cm in the vertical direction and 50 cm in the horizontal direction. The digital camera associated with the TOPOSYS system provides digital aerial photographs of 50 cm resolution. The DSM provided by the TOPOSYS system can be processed to eliminate the man-made features and vegetation to derive the associated DEM.
Falcon II is an opto-electronic LIDAR system (Light Detection And Ranging) developed by TopoSys for three-dimensional data acquisition of the earth’s surface. The measuring method for generating digital elevation models is based on active distance measurement by means of a laserscanner and is complemented by GPS positional determination and inertial navigation system. In parallel with this, a passive RGB/NIR line scanner has been integrated for the direct generation of the digital RGB and CIR true ortho images.
The Falcon II design is based on expertise of many years’ standing in the development and practical operation of the LIDAR TopoSys I and has been optimized for the rough service conditions in aircraft and helicopters.
Falcon II comprises essentially three units:

  • Sensor rack .
  • Computer rack .
  • Operator console .

ZEISS RMK TOP 15 CAMERA SYSTEM

The RMK TOP features a modular design. The individual components form logical functional units optimized to the needs of practical application use. Special consideration has been given to the space available in the aircraft, the installation conditions and the necessity of component change. Highlights:

  • High-performance lenses with internal filters.
  • Image motion compensation by FMC and gyro-stabilized suspension mount
  • Stabilized camera axis ensuring small nadir angles.
  • Pulsed rotating-disk shutter with a constant access time of 50 ms .
  • Overlap control and pin-point photography .
  • Menu-driven central control by a compact computer and logging of the mission data.
  • Automatic v/h measurement for overlap control and FMC.
  • Automatic exposure control using the principle of image quality priority .
  • Integration into the GPS-supported WinMP photoflight management system .
Image motion caused by the forward motion of the aircraft is eliminated by FMC devices (forward motion compensation). The Camera is equ8ipped with a T-AS gyro-stabilized suspension mount. Stabilization combined with improved vertical alignment of the camera gives the user more scope for action during the photo flight. Highlights:
  • Use of high-resolution, low-speed b/w and color films .
  • Complete elimination of image motion .
  • possibility of missions in rough flight conditions .
  • greater overlap accuracy and higher accuracy in pinpoint photography .
  • increased range of flying altitude and photo scale .
  • increased usage of camera and aircraft .

NARSS HRPT Receiving Station

NARSS HRPT (High Resolution Picture Transmission) receiving station has been installed at NARSS headquarters in Cairo, Egypt to receive images from American polar orbiting weather satellites controlled by NOAA (National Oceanic and Atmospheric Administration). There are two instrument onboard NOAA satellites; AVHRR (Advanced Very High Resolution radiometer) whose purpose is to give information (reflectance or temperature) on different types of surfaces (sea, vegetation, ice, snow), or on cloud cover (top) and ATOVS (Advanced TIROS Operational Vertical Sounder) sounding system with IR (HIRS) and microwaves (MSU/AMSU/MHS), which is dedicated to measurements of the atmospheric vertical structures.
