We have developed the satellite transmission technology that decrease in service interruptions as much as possible even if the levels of radio wave from the satellite are degraded due to rain ...
Abstract: Experiments are described to study the morphology of artificial spread-F (ASF) irregularities by measuring the scintillation of VHF and UHF signals transmitted through the disturbed region ...
We are researching next-generation satellite broadcasting using a 21-GHz-band broadcasting satellite, which is considered as a promising transmission channel for future new broadcasting services ...
Abstract: The relative importance of radiowave propagation in space communications depends on the frequency of operation, local climatology, local geography, type of transmission, and elevation angle ...
the world’s largest sub-metre commercial remote sensing satellite constellation, said it achieved a 100 gigabit per second ultra-high-speed image data transmission rate in testing last weekend.
China has made history by successfully testing 6G satellite transmission achieving a data transfer speed of 100 gigabytes per second. In November 2020, China launched the world’s first 6G satellite ...
