Córdoba Ground Station (ETC)

• Córdoba Ground Station is operated by Argentine Space Agency, started in September 1996.

• Currently the Station acquires data from more than 16 satellites and delivers an average of 2000 high-level products and more than 30000 level 2 products per month.

• Geographical location :

Lat. : - 31° 31’ Lon. : - 64° 27’




• May 2008 started operational, as main node of the Argentinean Component for South America RARS.

• AAPP version 6.15 and Bufr encoder 3.83 are running.

• ATOVS L1C from Cordoba, Marambio and Santiago de Chile stations are collected.

• Bufr encoding of L1C produced by these three stations.

• Timeliness transfer of bufr archives via ftp to UK Met Office and National Met Service of Argentina to put them via GTS on RHT Washington.

Due to the Station excellent localization, it is possible to acquire regularly satellite data from Argentina, Paraguay, Uruguay, Chile, Bolivia, important part of Peru and south of Brazil.




Santiago Ground Station (ETS)

• Operated by the Meteorological Direction of Chile.

• Currently, the Station acquires data from GOES, TERRA / AQUA and NOAA.


Lat. : - 33° 15’ Lon. : - 71° 24’




While the geographical coverage of Santiago and Cordoba Stations. is similar, the first one has a larger coverage on the SW Pacific Ocean area.

• January 2010 became operational for South America RARS.

• AAPP version 6.13 is running.

• Timeliness L1C data on ETC server




Base Marambio Station (EBM)• Base Marambio Station is

operated remotely by CONAE.

• The Station acquires data from more than NOAA (HRPT) satellites and Feng Yun 1D with around 40 passes per day.


Lat.: - 64° 14’ Lon.: - 58° 38’

• June 2008 started operational for South America RARS.

• AAPP version 6.12 is running.

• Timeliness L1C data on ETC server

Delays from the start of the overpass at the stations to receipt of data at the Met Office




Base Marambio Station (EBM) in Antarctica

Since 7th June 2010 to present is out of service.

The delay to start EBM operational again is due to two reasons:

1- Technical problem : A part of Antena System was broken, the technicians crossed to Marambio twice, but it could not be repaired it in situ. It was decided to move it for repair in Cordoba station. At present, the part is repaired in Cordoba station, waiting a new Air Force crossing to be installed. 2- Logistic problem :During 2011 and 2012, crossings to Marambio by Argentine Air Force were few, irregular and the short time, delaying the part repair.




Future Plans

• A station is planned to install in Tierra del Fuego (situated in the southern part of Argentina ) in the near future.

• X Band GS will be installed.

• A satellite communication link, point to point ( 512 or 720 Kb/s ), is planned for to extend the current narrow band width from Marambio station to the continent (less than 64Kb/s ) in the near future.

Argentina




• Isla de Pascua no planned a HRPT station. But, if one is installed, facilities and staff would be available for its operation.

• Isla Juan Fernandez no planned a HRPT station .

• Punta Arenas and Frei to be determined as operational stations.

Chile




Ecuador

• Cotopaxi station was planned to be operative for 2010.

• X band reception capability.

• Geographical location : Lat. : - 0° 37’ 21” Lon.: - 78° 34’ 46”




Cotopaxi station was planned to be operative for 2010, but despite the efforts made, this has not been possible, basically the technical problems are follows:

1- Ingesting system is very old: runs on DOS.

2- Memory and network management: the system is unable to ingest data and connect to the network for processing data in other machine at the same time.

CONAE has already configured the server to process AAPP. The connection and the possibility of bringing their L1c for processing in Cordoba have been tested.

They have been working and looking for some solution to handle DOS or find some other alternative of ingestion.

Bandwidth 240 Kb/s.

Nowadays, they have no near future plans for replacement this system.




Cordoba Station : On going actions

NPP and METOP-B • NPP

CONAE will perform an upgrade on the Ground segment in order to be able to acquire and process NPP.

The Upgrade implies a current CONAE Antenna retrofit to fulfill the Mission Requirements (new Radio Frequency elements will be integrated). Purchase Order has been already delivered.

Deadline for this activity April 2013.

• METOP-B

CONAE will integrate a New Demodulator to the current system in order to be able to acquire METOP. Purchase Order has been already delivered.

Deadline for this activity February 2013.




Santiago Station : On going actions

NPP and METOP-B • NPP

Meteorological Direction of Chile (DMC) together with the Photogrammetric Air Service of Chilean Air Force requested budget from SeaSpace for purchasing/upgrading the equipments and antenna for the NPP reception. This action is planned for 2014 depending on the allocation of funds.

• METOP-B

DMC has carried out no actions to Metop-B reception yet, but a budget from SeaSpace will be requested for purchasing/ upgrading the equipments and antenna, for the Metop-B reception, whenever the reception of this satellite is free of charge.
