Review of Models of Black Bodies Used in Aerospace Vehicles: Part 2. Promising Models of Onboard Black Bodies.

The paper presents promising models of onboard black bodies based on phase transitions of high-purity substances or eutectic compositions and carbon nanotubes used in aerospace vehicles for the radiometric calibration measurements of the equipment to observe the Earth. Their design and technical specifications, advantages and disadvantages as well as the examples of their use and tests are described. [ABSTRACT FROM AUTHOR]
