“…The National Aeronautics and Space Administration (NASA) Advanced Communications Technology Satellite (ACTS) propagation experiment was designed to obtain slant-path beacon attenuation statistics at Ka-band frequencies (20.2 and 27.5 GHz) [1], [2]. These measurements were to be made in different rain-rate climate regions (or zones) within the United States and Canada to provide additional information for the design of low-margin satellite communication systems.…”

Satellite (ACTS) propagation experiment was designed to obtain slant-path attenuation statistics for locations within the United States and Canada for use in the design of low-margin Ka-band satellite communication systems. Experimenters at seven different locations have collected propagation data for more than two years. The propagation terminals used for the experiment were identical. A single preprocessing program was used by the experimenters to provide for automatic calibration, generation of attenuation histograms, and data archival. In this paper, the calibration procedures are described and estimates given for measurement accuracy. ACTS provided beacons at 20.2 and 27.5 GHz for use in making attenuation measurements. In addition to the beacon receivers, each ACTS propagation terminal has two total power radiometers with center frequencies at the beacon frequencies. The radiometers are used to establish the beacon signal reference levels needed for calculating beacon attenuation values. For the combined radiometer and beacon measurement system, the attenuation measurement error was less than a maximum of 1.0 dB and was generally less than 0.3 dB. The dynamic range for attenuation measurement varied from site to site depending on location relative to the peak of the satellite beacon antenna pattern. For locations within the continental United States, the dynamic range was better than 20 dB.

With the development of the times, social progress, the continuous improvement of human science and technology and cultural level, more and more high-tech science and technology are constantly applied in daily production and life, big data technology as one of the many high-tech is also accepted by people. In the era of big data, massive data can be accurately processed through the analysis of big data technology, which has great benefits for the development of some industries. In the current era of big data, there are still many problems in the development of China’s computer remote network communication technology. In order to deal with the difficulties faced by the current computer remote network communication technology in China, this paper puts forward the method of integrating big data technology with computer remote network communication technology, so as to provide powerful help for China’s computer remote network communication technology. The real-time transmission and analysis information of computer remote network communication technology is the trend of future development, and it must be analyzed and studied accurately. It is found that the method proposed in this paper is of great significance to promote the development of computer remote network communication technology.
