The article says that the first Czech satellite, named Troll, is set to be launched into orbit by SpaceX this October. This satellite is notable for its advanced hyperspectral camera, which allows it to capture images across parts of the light spectrum that are invisible to the human eye. According to what is written in the article, Troll will be able to detect chlorophyll in plants, monitor pollution in rivers, and assess soil nutrients from space. This capability positions it as a significant tool for both agricultural monitoring and environmental protection.
“When you put on night vision goggles, suddenly you’re able to see the outline of a person in the dark and various objects. A hyperspectral camera is something similar, except it can also see through plants and tell what chemicals are inside, or if there are enough nutrients or water in the soil.” - řekl Petr Kapoun, the head of TRL Space.
The article explains that this technology can identify diseases or fungi affecting crops, which could ultimately enhance agricultural production. Furthermore, the Czech Environmental Inspectorate plans to utilize the satellite's data to detect illegal landfills and waste dumps, even in forested areas where visibility is obstructed.
The article also highlights that Troll will orbit the Earth five to seven times daily, capturing a vast number of images during each pass. To manage this extensive data collection efficiently, the satellite is equipped with an AI module that processes and sorts images before transmission. Michal Mičora from TRL Space elaborates on this process, noting that the satellite captures a strip approximately 120 kilometers wide and only sends back high-quality images of areas of interest. The article concludes by mentioning that Troll is not only the first Czech satellite with a hyperspectral camera but also part of a broader plan by TRL Space to launch nine similar satellites by 2030.
