49 new Global Positioning System (GPS) receivers, 5 advanced (including low frequency) ionosondes, and five fluxgate magnetometers are distributed throughout South America in response to a conspicuous community need to understand the day-to-day variability of the low latitude and southern magnetic latitude ionosphere. The data stream produces a real "now-casting" and forecasting capability of ionospheric irregularities known as equatorial spread-F. The primary research target is prediction of radio frequency communication and navigation scintillations that are caused by these ionospheric irregularities. Distributed along a chain near 70 degrees west (70o W) longitude, from 32 degrees south (32o S) to 8 degrees north (8o N) latitude, the ionosonde chain and magnetometers provide unprecedented information concerning traveling ionospheric disturbances (TIDs), and gravity wave morphology, in addition to the GPS information on total electron content (TEC).

49个新的全球定位系统（GPS）接收机、5个先进的（包括低频的）电离层探空仪和5个磁通门磁强计分布在南美洲各地，以满足人们了解低纬度和南磁纬电离层的日常变化的显著需求。数据流产生了真正的“现在铸造”和预测电离层不规则现象的能力，即赤道扩展f。主要研究目标是预测由这些电离层不规则现象引起的无线电频率通信和导航闪烁。从南纬32度（32 S）到北纬8度（80 N），沿着西经70度（70 W）附近的一条链分布，电离层探空链和磁力计除了提供有关总电子含量（TEC）的GPS信息外，还提供了有关电离层扰动（TIDs）和重力波形态的前所未有的信息。
