高级成分探测器（ACE）RTSW系统正在持续监测太阳风，并提前一小时发出即将发生的重大地磁活动警报。NOAA发布的警告和警报允许那些对此类活动敏感的系统采取预防措施。RTSW系统以高时间分辨率从四个ACE仪器（MAG，SWEPAM，EPAM和SIS）收集太阳风和高能粒子数据，将数据打包成低速率比特流，并连续广播数据。NASA每天在下载科学数据时向NOAA发送实时数据。结合专用地面站（日本的CRL和英国的RAL）和现有地面跟踪网络（NASA的DSN和美国空军的AFSCN）的时间，RTSW系统可以全年每天24小时接收数据。原始数据立即从地面站发送到位于科罗拉多博尔德的空间环境中心，进行处理，然后发送到其空间天气操作中心，在那里它们用于日常操作;数据还被发送到位于日本平所的CRL区域警报中心，美国空军第55空间天气中队，并放在万维网上。数据在离开ACE后的5分钟内被下载、处理和分发。RTSW系统还使用低能高能粒子来警告即将到来的行星际冲击，并帮助监测可能对卫星系统造成辐射损害的高能粒子通量。
The Advanced Composition Explorer (ACE) RTSW system is continuously monitoring the solar wind and produces warnings of impending major geomagnetic activity, up to one hour in advance. Warnings and alerts issued by NOAA allow those with systems sensitive to such activity to take preventative action. The RTSW system gathers solar wind and energetic particle data at high time resolution from four ACE instruments (MAG, SWEPAM, EPAM, and SIS), packs the data into a low-rate bit stream, and broadcasts the data continuously. NASA sends real-time data to NOAA each day when downloading science data. With a combination of dedicated ground stations (CRL in Japan and RAL in Great Britain), and time on existing ground tracking networks (NASA's DSN and the USAF's AFSCN), the RTSW system can receive data 24 hours per day throughout the year. The raw data are immediately sent from the ground station to the Space Environment Center in Boulder, Colorado, processed, and then delivered to its Space Weather Operations center where they are used in daily operations; the data are also delivered to the CRL Regional Warning Center at Hiraiso, Japan, to the USAF 55th Space Weather Squadron, and placed on the World Wide Web. The data are downloaded, processed and dispersed within 5 min from the time they leave ACE. The RTSW system also uses the low-energy energetic particles to warn of approaching interplanetary shocks, and to help monitor the flux of high-energy particles that can produce radiation damage in satellite systems.
