LETTER DATED 13 NOVEMBER 2014 FROM THE PERMANENT REPRESENTATIVE OF THE DEMOCRATIC PEOPLE'S REPUBLIC OF KOREA TO THE UNITED NATIONS OFFICE AT GENEVA ADDRESSED TO THE PRESIDENT OF THE HUMAN RIGHTS COUNCIL
The puppet forces even developed a satellite air navigation device to be mounted on
balloons for scattering leaflets, a program for controlling balloons to suit the wind direction
and speed and the technology of radio transmission system for sending e-leaflets into the
rear of the DPRK side, and have provided them free to human scum.
(...) invited Pak Sang Hak and Kang Chol Hwan, representative of the Center for Strategy
toward the North, to the Silicon Valley and showed them technology for disseminating
USB, DVD and other media to the area of the DPRK side through GPS.
In July it staged a contest of information and telecommunications technology for
breaking through the information network of the north in a worldwide scale with the
attendance of the defectors and handed over to them ultra-modern development data for
conducting anti-DPRK smear psychological campaign.

REPORT ON THE UNITED NATIONS/EUROPEAN SPACE AGENCY/NATIONAL AERONAUTICS AND SPACE ADMINISTRATION OF THE UNITED STATES OF AMERICA WORKSHOP ON THE INTERNATIONAL HELIOPHYSICAL YEAR 2007, ABU DHABI AND AL-AIN, UNITED ARAB EMIRATES, 20-23 NOVEMBER 2005
一个典型的 RENOIR台站通常具有下列设备:(a)一个单频 GPS闪烁监测器
阵列,这些监测器能够对发生的不规则现象及其规模、方向和速度进行测量;
13
A/AC.105/856
(b)一个双频 GPS 接收器,该接收器测量的是电离层的电子总含量(如果可以将
站点设在一个已经有双频 GPS接收器的地方,那么就不再需要新的双频 GPS接
收器);(c)一个全天空成像系统,该系统对两种不同的热层/电离层辐射进行测
量,可以借此观察不规则现象的两维结构/运动(也可利用这些数据计算电离层
的密度和高度);(d)两个微型法布里——珀罗干涉仪(MiniME),这些仪器提
供对热层中性风和温度的测量数字(两个干涉仪大约相隔 30 万米,以便进行普
通量的收发分置测量)。
(...) 单频 GPS 闪烁监测器阵列需要一个大约 100
米 x100 米的空间,上面可以交叉架设五根天线。同样,也需要为每个监测器提
供安装控制计算机的最小空间。 (...) 对于最近在太阳高峰期(2000-2002 年)收集的数据
进行的分析表明,单频和双频 GPS 接收器在严重的闪烁活动期间都会发生重大
误差。所有的 SCINDA 站点现在都配有 GPS 闪烁监测器,模型也在开发之中。
