Replacement of the current flight and ground system architectures requires innovative ways to meet the growing user needs while balancing cost. The NESDIS Ground Enterprise Study (NGES) was undertaken over three years to identify the most capable and cost-effective ground architecture(s) for NESDIS to invest in for near-, mid-, and long-term success of its mission. NGES addressed the full range of NESDIS ground operations including satellite operations, science operations and data operations covering major near-term activities beginning in 2023 for evolving the next-generation ground systems needed to support current architectures, and support of the future target reference space architecture for operation in 2035-2050. This study identified multiple alternative architectures (and combinations of architectures) to consider variations of how NESDIS could accomplish key functional attributes that support ground operations functions.
The authors will describe the study and its purpose, review activities over the last year, and introduce the remainder of the session on Next Generation Ground Systems Architecture for Weather Satellites.
