Joint Polar Satellite System

Ground Operations

Ground System Brochure

The spacecraft directly transmits stored mission sensor data to a receiving station in Svalbard, Norway, and will also provide continuous direct broadcast of real-time sensor data. The mission data will be routed on communications networks from Svalbard to the continental United States.

Data from Suomi NPP will be distributed to meteorologists at NOAA and the U.S. Department of Defense, as well as to climate researchers around the globe. Many of these measurements continue long-term climate data records from existing Earth-observing missions such as Aqua, Terra and Aura.

The Suomi NPP mission will continue critical weather and climate measurements and reduce risk for the next generation meteorological satellite system, by flying a suite of new, advanced-technology remote sensing instruments. The measurements taken provides critical data to support operational weather forecasting, as well as long-term climate research.

Facilities

WCDASWallops Command and Data Aquisition Station (WCDAS)
NOAA Satellite Operations Facility (NSOF)

Located in Suitland, Maryland, NSOF will house the majority of GOES-R series mission operations. The EM, PG, and PD functions will be performed here. The majority of operations and product staff will also be housed at NSOF. Four existing 9.1-meter antennas were upgraded for compatibility with GOES-R satellites. These antennas will maintain compatibility with existing GOES satellites and will operate continuously for the life of the GOES-R series.

Wallops Command and Data Aquisition Station (WCDAS)

WCDAS GOES-R Antenna Construction Site. Located in Wallops, Virginia, the WCDAS will be the primary site for space-to-ground radio frequency (RF) communications. Level 1b data will be processed at WCDAS to produce GOES Rebroadcast (GRB) for satellite uplink. WCDAS will also provide uplink to the satellites to support the Unique Payload Services (UPS). Three new 16.4-meter antennas have been constructed at WCDAS. They are designed to withstand sustained winds of 110 mph (Category 2 hurricane) and to survive (in a stowed position) gusts of up to 150 mph (Category 4 hurricane). These antennas will be compatible with existing GOES satellites and will operate continuously for the life of the GOES-R series.

Consolidated Backup (CBU) Facility

Located in Fairmont, West Virginia, the primary function of the CBU will be to support contingency operations and perform all of the critical functions of NSOF and WCDAS through the production and distribution of life and property products. The CBU will provide product generation for all Key Performance Parameters (KPPs). The CBU will also serve as a backup during system/equipment testing or maintenance. Three new 16.4-meter antennas have been constructed at the CBU. They are designed to withstand sustained winds of 110 mph (Category 2 hurricane) and survive (in a stowed position) gusts of up to 150 mph (Category 4 hurricane). These antennas will be compatible with existing GOES satellites and will operate continuously for the life of the GOES-R series.
