Cartosat-1 satellite is the first Indian Remote Sensing Satellite capable of providing in-orbit stereo images. The images are used for Cartographic applications meeting the global requirements. Cameras of this satellite have a resolution of 2.5m. The satellite provides stereo pairs required for generating Digital Surface Models, Ortho Image products, and Value added products for various cartographic applications. The satellite carried two Panchromatic Cameras, namely PAN-A (Aft) and PAN-F (Fore). The PAN-F camera is fixed at a forward tilt of 26o and PAN-A camera is fixed at an aft tilt of -5o to provide in-orbit stereo images.
The major objectives of Cartosat-1:

  • Design and develop an advanced 3-axis stabilized remote sensing satellite for providing enhance spatial resolution (better than 2.5 m) with stereo imaging capability for the cartographic applications.
  • Develop new areas of applications to take full advantages of high spatial resolution and stereo imaging capability for cartographic, urban planning, infrastructure development and 3D terrain analysis.
