  Satellite Data Acquisition
 
At present the Republic of South Africa (RSA) under the guidance of the Department of Science and Technology (DST) is formulating a South African Earth Observation Strategy (SAEOS) which will be in line with the Global Earth Observation System of Systems (GEOSS) to which South Africa is a signatory and which has as its aim the upliftment of people worldwide through better management of the environment using remote sense data which will be available to all. The acquisition of remote sense data over the South African and African region is therefore of national importance and the satellite data acquired at Overberg Toets Baan (OTB) will support the Department in contributing positively to the aims of this international programme and to achieving one of its strategic objectives i.e. contributing to a better world.

   
  Location of ISSA and OTB ground station
   
  Overberg Test Range (OTB) ground station is situated near Arniston / Waenhuiskrans, just east of Cape Agulhas, the southern most tip of Africa.

  History
   
 
In 1981 there was a strategic requirement for the development of a satellite based reconnaissance system for the South African Air Force capable of monitoring airfields, troop movements, borders and coastline reconnaissance.

The system consisted of:

  • A Low Earth Orbit reconnaissance Satellite (Greensat)
  • A Launch Vehicle
  • A Satellite Integration Facility (Houwteq now ISSA)
  • A Launch Facility (OTB) from where to launch and track the satellite

The facility closed down in 1994, but was leased and recommissioned in 1998 by the DoC for training and remote sensing purposes.

   
  Equipment and Products
   
 
The OTB site has a 10 metre X-band tracking antenna and is currently tracking the Terra and Aqua satellites and receiving earth observation data from the MODIS sensor.

The data are archived, catalogued and quick looks are generated. The data are archived in level zero format and may be processed to level 1a, 1b and level-2.

Previous involvement with the Marine and Coastal Management Unit of the DEAT saw the processing of Sea Surface Temperature, and Ocean Colour products.

Currently the aim is to upgrade to the reception of Sumbandilasat data and to provide such data and MODIS imagery to the South African Earth Observation Network (SAEON).
