A primary limitation for accurate specification and forecasting of the thermosphere‐ionosphere (TI) system is uncertainty in the system forcing. This significantly impacts users who have operational and real‐time interests in the current and future state of the TI system. Since Global‐Scale Observations of the Limb and Disk (GOLD) observations are expected to provide information about both the current state and forcing of the TI system, GOLD products could be an operational asset if they could be provided in near real time. Production of GOLD data products requires knowledge of the satellite pointing and location. The current scientific processing implementation contains an operationally significant delay to await definitive location and as‐flown pointing. We present the results of a demonstration low‐latency processing system that assumes the nominal satellite position and pointing to produce low‐latency GOLD data products. The resulting products are reasonably similar to the scientific version but are available within minutes rather than hours.

近实时GOLD数据产品的可行性

热球-电离层(TI)系统的准确规格和预测的主要限制是系统强迫性的不确定性。这会对在TI系统的当前和未来状态中具有运营和实时兴趣的用户产生重大影响。由于预计全球范围的肢体和磁盘观测(GOLD)观测将提供有关TI系统当前状态和强迫的信息,因此,如果可以实时提供GOLD产品,则它们可能是一项运营资产。生产GOLD数据产品需要了解卫星指向和位置。当前的科学处理实施包含大量操作延迟,需要等待确定的位置和飞行指示。我们介绍了一个示范性的低延迟处理系统的结果,该系统假定卫星名义位置并指向产生低延迟的GOLD数据产品。生成的产品在某种程度上类似于科学版,但仅需数分钟而不是数小时即可提供。
