Satellite designers know what each photographer understands the act of getting closer to the subject to obtain better photographs. Not only visible examples of color but all over the spectrum. The lower altitude often enhances such aspects as communications, radar, lidar, and GPS. The closest a satellite comes to Earth, the more it experiences atmospheric drag. And it can mean an unplanned Earth-Observing (EO) satellite plummet to annihilation.
Getting satellites orbit closer to the Earth is a kind of Holy Grail in observation of Earth. If you could get a satellite nearer, you can decrease the payload in a highly elliptical orbit and have the same outcomes as a satellite, thus lowering costs. Alternatively, you can sustain a similar payload and show even better performance.
VLEO satellites have many advantages. We track hurricanes, monsoons, wildfires, and climate change using satellites. We use it to supervise farming, guide the progress of weapons, overseas fishing vessels, and monitor the emergence of disease outbreaks. GPS coverage, Internet access, and a variety of other telecommunications services provided by satellites.
Good outcomes imply higher-resolution images and videos, better signal-to-noise proportions, and lower computation jitter for Earth-observing satellites. Extra advantages comprise enhanced geospatial location accuracy, advancements in connection-budget interactions, and higher capacity to insert propulsion systems. The obstacle to all such changes is the atmosphere of the Planet. The nearer a satellite ends up getting to Earth, the denser the atmosphere becomes, creating more drag. Without even a way to combat the pull, satellites too close to Earth would experience orbital deterioration and plunge into atmospheric catastrophe in a matter of a few weeks.
The most prevalent problem facing VLEO maybe environmental drag and unnecessary orbital decay, however as the scientists point out in their paper, this is only one of the hurdles. The ESA was already consistently working at its Materials, and Electrical Components Laboratory was utilizing its atomic oxygen generator. The engine uses lasers to generate atomic oxygen and measures its impact in a vacuum on materials.
Even radiation is an issue in Earth’s orbit. The radioactivity atmosphere to which a spacecraft exposes in LEO includes a combination of energy particles stranded by the Earth’s magnetic field, cosmic rays, and interstellar galactic rays. That radiation on spacecraft poses a danger to sensitive equipment.
In conclusion, there is also a need for solutions to the problems of atomic oxygen depletion, atmospheric drag. If the history forecasts the future, it would seem probable that the future will come up with solutions to those problems. When they do, Earth observation, GPS accuracy, and VLEO’s other advantages will come to pass.
