Optics in Remote Earth Sensing Tasks

Constructor extension Introsat™ includes groups of topics "Space optics" and "Processing of space images".

It is used for conducting in-depth classes in satellite engineering, space optics, problems of remote sensing of the Earth.

The kits allow you to conduct introductory workshops on optics, assemble functional models of CubeSat 3U satellites with a high-resolution optoelectronic system based on a Raspberry Pi single-board computer and a Maksutov-Cassegrain mirror-lens optical system

The "Processing of space images" section covers the beginnings of working with space data and its application in geoinformatics problems.

The content of the course and the completion set of the basic set allow you to conduct practical classes, including on topics:

  • Fundamentals of optics and remote sensing of the Earth
  • Geometric optics and spectral analysis
  • Refractors, classification of telescopes, calculation and assembly of the Keppler telescope, making observations
  • Reflectors, mirror-lens schemes, Maksutov-Cassegrain scheme, optical elements
  • Image quality, types of aberrations, collimators, alignment
  • Working with Raspberry Pi on-board computer
  • Cameras and specialized imaging software
  • Space images and how to work with them
  • Types of surveys by the used parts of the EM spectrum, computer processing of images
  • Working with optical images
  • Working with thermal images
  • Working with radar images

The recommended age of students is 14-18 years old. Up to 3-4 students can work with one set. To work requires a PC or laptop.
