Electromagnetic compatibility and radio spectrum matters - meteorological aids met aids - radiosondes to be used in the 400 , 15 mhz to 406 mhz frequency range with power levels ranging up to 200 mw - part 1 : technical characteristics and test methods v1 . 1 . 1 电磁兼容性和无线电频谱情况.计量辅助设备.功率电平范围不大于200mw的400 . 15mhz至406mhz频率内使用的无线电探空仪.第1部分:技术特性和试验方法
Measurement of pressure , temperature and humidity operated in much the same principle as the older version of radiosonde , but computation of wind was made use of the vlf ( very low frequency in the range of 10 - 13 khz ) signals of a world - wide navigational network , omega 该系统量度高空气压、气温及湿度的方法与旧式无线电探空仪大致相同，但在测风方面则采用了一种新的概念，利用世界性奥米茄导航站网的甚低频信号（ 10 - 13khz ）来计算出高空风向和风速，无需用雷达追踪探空仪位置。
