is stationary and less than 5 and 15, respectively, which is dierent from the case of Fig. 10 (c).4.3Correlatione correlation between the PLR and the number of error detections by CRC in Figs. 10, 11, and 12 is shown in Fig. 13. Since the log output frequency does not coincide ((b) is 500 ms and (c) is 200 ms), the average for 1 ms is used to estimate the correlation. e correlation coecients of Figs. 10, 11 and 12 are 0.088, 0.303, and 0.295, respec-tively, which is not high.4.4Upper limit of throughputere are cases in the WINDS communication line where quality check by CRC is necessary during data transmission. e throughput is almost over the target FiF11　Results of network disturbance experiment (1)FiF12　Results of network disturbance experiment (2)FiF13　Correlation between PLR and number of error detection by CRC, and correlation coefficient ((a) 0.303 and (b) 0.295)(a)(b)(c)(a)(b)(c)(a)(b)1733-12 A Network Quality Check Tool via HpFP Protocol on WINDS Satellite Link
