SUBJECT: Planned Updates to GGSS F&PS Document

The Geostationary Ground System Sustainment (GGSS) Functional and Performance Specification

(F&PS) document included in this RFI represents the current technical baseline, updated since the development of the system to reflect the added, removed and update capabilities. There are several major updates to the system planned between the technical baseline represented in the attached F&PS and the GMSE projected contract transition date in 2028, falling into the two main categories of 1) cloud migration and 2) system simplification. The updates to the F&PS to account for these planned updates are currently underway. Some of the requirements that are removed from GGSS may be re-introduced in the GeoXO requirements due to anticipation of a new solution being implemented in the

2030 timeframe.

The types of requirements potentially impacted by the two main updates to the system are:

1) Cloud Migration of Data Operations to Cloud

a. Deployment location restrictions (Section 4.2)

b. Specification of DO capabilities to on-premises sites for primary or backup purposes

(throughout)

c. Product Generation and Dissemination requirements pertinent to processing locations

(as specified in Sections 7 and 8)

d. Separation of requirements (or solutions) for areas such as Enterprise Management, Configuration Management, Auditing between on-premises and Cloud. In some cases requirements are high-level to be applicable to cloud and on-premises solutions separately, but rationale may need to clarify that common solutions are not required.

e. Extensibility, Modularity and Scalability (Section 4.14) will be modified to take cloud computing benefits into account

2) System Simplification

a. Removal of the OSL-2 location

b. Reduction in on-premises footprint including removal of Product Processing Zone

(PPZ) with DO move to Cloud and reorganization of existing environments

c. Decommissioning of SCADA Operations Zone (SOZ) Development Environment

d. Decommissioning of Raw Data Recorder

GEO Memo: Planned Updates to GGSS F&PS 12/2/24

e. Decommissioning of Antenna Link Monitor as represented in GGSS requirements

Although not directly related to requirements, there are a series of additional capabilities that will be retired from the system:

a. Removal of a triply redundant MM server as launch commit criteria

b. Decommissioning of T&C Last Ditch Servers

c. Retirement of the Mission Management Test and Demonstration System (MMTDS)
