Resources to educate students, teachers, and the general public about meteorology, space science, earth-observing satellites, weather phenomena and benefits GOES-R will provide to society.
Information and resources to ensure that the user community is prepared for the new types of satellite imagery and data that will be available from the GOES-R satellite series.
GOES-R Rebroadcast (GRB) is the primary space relay of level 1b data products from GOES-R. Level 1b products consist of instrument data with radiometric and geometric correction applied to produce parameters in physical units. These data are available to all users with GRB receivers in view of a GOES-R series satellite at the East or West operational longitudes.
GRB will replace the GOES VARiable (GVAR) service. GRB will provide full resolution, calibrated, navigated, near real-time direct broadcast data.
The content of the data distributed via GRB service will be the full set of Level 1b products from all instruments onboard the GOES-R series spacecraft. This concept for GRB is based on analysis that a dual-pole circularly polarized L-band link of 12 MHz bandwidth may support up to a 31 Mbps data rate – enough to include all ABI channels in a lossless compressed format as well as data from GLM, SUVI, EXIS, SEISS, and MAG.
GOES-R Data Processing, Flow, and Storage
GOES-R Rebroadcast (GRB) Transition Information
•
The content distributed by GRB will be the full set of level 1b products, including data from all ABI channels and the other GOES-R instruments (GLM, MAG, SEISS, SUVI, EXIS).
•
GOES users must acquire new hardware, or upgrade their existing GVAR systems in order to receive GOES-R data.
•
Existing GVAR systems will need new receiver antenna hardware, as well as new signal demodulation hardware and computer hardware so that they are able to handle the large amount of GOES-R data.
•
CLASS will provide permanent archive for GOES-R data as part of its mission to be the single data repository for NOAA.
The GOES-R Rebroadcast (GRB) Product Users’ Guide (PUG)(updated Dec. 2012) is now available. Please direct all questions and concerns to the GOES-R Ground Segment Project via Randy Race, randall.race@nasa.gov.
GRB Simulators
A GRB simulator is being developed and will be available beginning in May 2013. The intent is to provide the simulator to the vendors that manufacture GRB receivers. The simulators will be made available to verify GRB receive system compatibility with the GRB transmission. Details on how vendors of GRB receivers can request the simulator are under development. Once that information is available, it will be posted here.
Purpose:
•
On-site testing of user ingest and data handling systems, aka GRB field terminal sites.
•
Simulates GRB downlink functionality by generating Consultative Committee for Space Data Systems (CCSDS) formatted GRB output data based on user-defined scenarios, test patterns, and proxy data files.
Key Capabilities and Features
Transportable
Fully self contained
Configurable hardware units
Outputs simulated GRB
“Off-line Mode” to create and setup configurations and scenarios
Also, create test patterns and input proxy data
“On-line Mode” to continuously output GRB data stream at IF or baseband levels
