Very Low Frequency (VLF) spectrograms show sometimes sets of lines called MLR (Magnetospheric Line Radiation) with frequency spacing close to 50 or 60 Hz. It is very tempting to attribute these MLR to Power Line Harmonic Radiation (PLHR). PLHR are the ELF and VLF waves radiated by electric power systems at the harmonic frequencies of 50 or 60 Hz. Here we show for the first time large scale MLR observed simultaneously on ground and on board a low altitude satellite which is flying over the same zone.

应用背景最近的研究表明，超过70%的可用频谱没有有效地利用。由于频率不足，带宽变得昂贵。因此，为了有效地利用频谱，我们需要嗅的频谱，以确定它是否被使用的主要用户或不。认知无线电是指利用频谱感知的信息通过无线电参数。在文献中提出的各种频谱感知技术，但仍有研究人员在这一领域探索更先进的方法。频谱感知技术主要有三类：发射检测、接收检测和干扰温度检测。关键技术联邦通信委员会（联邦通信委员会）负责对美国的州际通信，管理和许可的电磁频谱在美国和它执行要求在所有无线电频率波段的跨站干扰。他们许可段特定的用户在特定的地理区域。只要遵循一定的权力规定，任何人都可以使用少量的、小型的、无牌的乐队供人使用。随着最近在个人无线技术的蓬勃发展，这些无牌乐队已经变得拥挤，从无线网络到数字的无线电话。为了打击过度拥挤，联邦通信委员会一直在探索新的方法来管理射频资源。基本的想法是让人们使用许可的频率，只要他们可以保证受原许可证持有人的干扰将是最小的。随着软件和认知无线电技术的进步，这一方法在地平线上是可行的。认知无线电能够巧妙地感知和适应随着环境的变化改变其传输参数，如调制，频率，帧格式等。

Memory Scanner will scan the whole memory built into your device. You will find all kinds of data - system entries, application data, as well as your personal data. You may query your searches and view their results either as text or as binary data. To speed up your searches you can define filters. -Memory Scanner will scan the whole memory built into your device.
