China has achieved a groundbreaking milestone in aerospace technology by overcoming the challenges posed by the "black barrier," a phenomenon in the ionospheric region of the Earth's atmosphere. This barrier causes significant interference and attenuation in the transmission of radio waves and high-energy particles, presenting a major obstacle in aerospace communications and safety.
The "black barrier" is characterized by lower ion density compared to its surrounding areas, creating a "hole"-like zone that disrupts signal transmission. This interference not only affects aerospace communication but also impacts the stealth capabilities and combat effectiveness of aircraft. Additionally, it poses challenges for spacecraft and astronaut communication equipment during atmospheric passage.
Various solutions have been proposed to mitigate the effects of the black barrier, including the use of high-frequency radio waves, optical communication, and laser communication technologies. These methods aim to overcome signal attenuation, interference, and transmission rate limitations encountered within the black barrier.
China's approach to tackling this challenge involved utilizing high-frequency radio waves during the Shenzhou 15 mission. By leveraging S-band frequencies, which penetrate the lower layers of the black barrier more effectively, communication between the spacecraft and ground stations, including the Tiangong Space Laboratory, was established. Additionally, signal enhancement technology was employed to bolster communication reliability, establishing a relay channel between the spacecraft and ground receivers via relay stations.
Overall, China's success in overcoming the "black barrier" represents a significant advancement in aerospace technology, enhancing communication reliability and safety in ionospheric regions and contributing to the country's prowess in space exploration.
