摘要
利用2021年3—9月长江中下游往返平漂探空试验安庆站的数据,将北斗卫星导航系统与L波段探空系统探测数据进行对比分析,统计两者的相关性和测量差值,进一步了解新型智能北斗卫星导航系统产品的准确性和可信度。结果表明:两者温度、海拔、测风结果一致性较好,温度和海拔相关系数分别为0.987和0.992,风速和风向相关系数分别为0.879和0.720,温度、海拔、风向、风速的差值较小,北斗卫星导航系统探测性能较好。
Using the data from the Anqing Station during the round-trip drift sounding test in the middle and lower reaches of the Yangtze River from March to September 2021,a comparative analysis was conducted between the detection data of the Beidou satellite navigation system and the L-band sounding system.The correlation and measurement difference between the two systems were statistically analyzed to further understand the accuracy and credibility of the new intelligent Beidou satellite navigation system product.The results showed that the temperature,altitude,and wind measurement results of the two were consistent,with correlation coefficients of 0.987 and 0.992 for temperature and altitude,and 0.879 and 0.720 for wind speed and direction,respectively.The differences in temperature,altitude,wind direction,and wind speed were small,indicating good detection performance of the Beidou satellite navigation system.
