What is NDVI?
NDVI (Normalized Vegetation Index) is a measure of plant health, which is calculated by how the plant reflects and absorbs different light waves.
How does a satellite work?
To move in orbit around the Earth, the device must have an initial velocity equal to or greater than the first cosmic velocity. AES flights are carried out at altitudes of up to several hundred thousand kilometers. The lower limit of the satellite’s flight altitude necessitates avoiding the process of rapid braking in the atmosphere.
