Direct Broadcast + Alerts + Fast Delivery Products: From Satellites to End Users

Some applications, like emergency management, requires that data reach the final user as soon as possible after the satellite pass over the ground station. There are final users interested in different products, over different geographic regions, and each one have different resources and infrastructure. Then, it is necessary to process the down linked data in near real time to produce outputs according the needs and expectations of the final users, and to deliver the products quickly.
In order to provide to the end users the appropriate information with minimum delay, we have indicated some particular situations to the production software, related to the requirements of some projects. If some of these particular situations are observed, e-mails and/or messages to cellular phones are generated and sent automatically to the registered final users for that type of event, and the specific products are generated and saved in a FTP server.
This type of system is being used in different applications and with data from several satellites. Some results will be shown.
Abstract

•Córdoba Ground Station started operations in 1997 with the reception of satellite data from Landsat 5, ERS 1/2 and SPOT
•Today the Station acquires data from more than 15 satellites and delivers an average of 1000 high level products per month.
Córdoba Ground Station. (ETC – CETT )

Facilities (related to DB)
Antennas: 2 DATRON X/S band, 2 Quorum L and
Ingestion: MEOS (X band), MEOS POLAR, Vexcel, CONAE
Processing: MEOS (used up to L0) , IMAPP, SEADAS, CONAE

DB brings the satellites “closer” to the Ground Station
Software packages allow near real time data processing
But in many cases the End Users are still very far from the data

Frequently this interface is the
problem

In other words….
What can a fireman do (as a end user of satellite data) in benefice of the rural
inhabitants and of the environment of a remote area, with a multi-megabyte,
complex format product, with some days of delay, after the fire ends?
G. Cabrera - International EOS/NPP Direct Readout Meeting – Oct/2005 (12)
The problem is to provide useful products to end users,
This is:• Near real time
• Easy to use
• Specific data
Customization of contents, format, and delivery methods for each kind of
product
G. Cabrera - International EOS/NPP Direct Readout Meeting – Oct/2005 (13)
Example: Hot Spots
Satellite Pass Acquisition
MODIS – AVHRR – HSTC (SAC-C)
•There are redundant Antennas, RF equipment and ingestion systems
•Specific systems for each satellite, backup systems.
Sat?=SAC and Night
Process to L1B
Use MODIS CloudMask
Process Hot Spots
• Synergy
• Specific software for each sensor

Example: Hot Spots (cont.)
E-mail PNMF(Office)
SMS PNMF(Field)
All detected Hot Spots
Detected Hot Spots in each area
Publish in WEB QL and Hot Spots list
Subsets L1B
Comp. with volcano list E-mail / SMS VAAC
Detected Hot Spots coincident with volcanoes
Of all Hot Spots areas

Comments:
• In the summer 2004/2005 in Patagonia this system was effective in early detection of fires in remote areas. Fires were detected by this system earlier than others.
• The last 2 events of Villarica Volcano were detected and informed earlier than other systems
• Gas Flares are used as tests for volcanic alerts
G. Cabrera - International EOS/NPP Direct Readout Meeting – Oct/2005 (17)
Products for the National Weather Service (SMN)
• All AQUA an Terra passes
•Atmosphere products are generated with IMAPP
• SMN users and analysts are e-mailed in RT
• Products are passed in the format specified by SMN to the SMN intranet
• SMN and CONAE are collaborating in the improvement of this scheme

But....
There are some cases in that the end users are really near to the DB systems…..
