Ground Architecture
The Ground Segment encompasses the following four major
functions:

Two operational satellites positioned at 137 degrees
West longitude for the Western Operational station,
and at 75 degrees West longitude for the Eastern
Operational station. During the on-orbit storage
period, the satellites will be positioned at 105
degrees West longitude and a Launch/Check-out position
is reserved at 90 degrees West longitude. |
1) Mission Management (MM)
2) Enterprise Management
(EM)
3) Product Generation (PG), and
4) Product Distribution
(PD).
These functions comprise the core Ground Segment
functional architecture.
Mission Management (MM) includes mission scheduling,
satellite (including instrument) operations, satellite
state-of-health trending, orbital analysis, and ground
operations.
Enterprise Management (EM) supports all operational
functions by monitoring, assessing, and controlling
the configuration of the operational systems, networks,
and communications for the GOES-R ground segment. EM
serves as the “glue” that links the MM,
PG, and PD elements and provides for a degree of automated
control. EM thus contributes to greater operational
availability, efficiency, and safety of the GOES-R system.
Product Generation (PG) includes algorithm support,
processed raw data, processing to Level 1b (including
calibration, navigation and registration), generation
of the data for rebroadcast and for higher level data
creation including operational derived products. The
government will provide the necessary science algorithms
for the generation of user products.
Product Distribution (PD) includes distribution of Level 1b, Level 2+, and derived products to user portals while addressing interfaces with the user for accessing GOES data. The primary user portals include the GOES-R satellite series (e.g., for uplink of Global Re-Broadcast (GRB)), NOAA’s National Weather Service (NWS) for AWIPS, and a GOES-R User Access Point at NESDIS/OSDPD.
