Satellites Eutelsat 25bSatellites are one of the most sophisticated and modern equipment invented, developed and used by mankind. Most of the countries of the Blue Planet have recourse to them for various purposes. Satellites are classified in nine types: for (1) astronomy, (2) atmospheric studies,  (3) communication, (4) navigation, (5) reconnaissance, (6) remote sensing, (7) search and rescue, (8) space exploration and (9) weather.

Satellites vary in size and mass: Nano Satellites are of about 10 kg, Mini Satellites range between 10 to 100 kg and bigger ones may be about 1141 kg or more. The first Satellite was launched by USSR on 04 October 1957- called Sputnik 1 and followed by USA on 01 February 1958- called Explorer 1. Up to 2013 there are 61 countries which have their own Satellites. The most recent one was launched last week-29 August 2013 by South Korea. EUTELSAT 25B, a multipurpose Satellite, of a liftoff mass of 6,300kg, was launched in French Guiana by Ariane 5.

    Satellite RASCOM-QAF 1 was launched by Rascom Star-QAF Company which was registered in Mauritius- a member of Regional African Satellite Communication Organisation (RASCOM). It was rocketed into space by Ariane 5GS on 21 December 2007. Its mission is to provide direct TV broadcasts and Internet access for Africa. Mauritius does not own any Satellite so far. There are, currently, at least 8,322 Satellites that are in the Space, of which only 4,000 are in service. The rest are outdated and left at a higher orbit or been destroyed into pieces or debris.

   A Satellite is a compact equipment. It has a physical body which is known as a Bus. This Bus houses many sophisticated tools, apparatuses, cameras, sensors, instruments, batteries and such equipment required to operate according to the programmed mission. The body also protects the contents against solar radiation and hazards like debris, objects and particles that hover in space.

   A Satellite is not fully dependent. It relies on Launch Vehicles, like Columbia of USA or Ariane of France, to be sent in space. Satellites are in different shapes. They are fixed in Space Capsules which are mounted in the Launch Vehicle that transports them in the cosmos. They start their life in Space in the orbit ranging between 240 km to 36,200 km altitude. As soon as they reach the site, they detach themselves with the help of the energy generated by their batteries. They stretch their arms, deploying them as wings on which solar panels are fixed. The solar panels convert solar rays into energy which is required for all the movements of the Satellites and for carrying out their operations and missions intended for (see above).

 Map of regions WMO  The World Meteorological Organisation (WMO), whose Headquarters is found in Geneva, Switzerland, has divided the whole globe into six Regions. Mauritius is in Region I. The Mauritius Meteorological Services (MMS) has therefore the jurisdiction, on behalf of the Government of Mauritius, to manage Climate and Weather issues according this delimitation. But I do not agree with this, because this zone gives us a very limited opportunity of forecasting all Natural Hazards of our region (see figure).

   Our concern here regards Climate and Weather. There are two basic types of Climate and Weather Satellites:
(i)    Geostationary Satellites operate along the Equator at 35,800 km above Mother Earth (Blue Marble). They stay in the orbit at a fixed spot and move according to the speed and rotation of the Earth. Our Blue Planet rotates on its axis from West to East in 24 hours making a day and a night, so the Satellites move on the same track day and night.   

(ii)    A Polar Satellite operates at 50 km higher in altitude, that is, 35,850 km from the Earth. It moves between the North Pole and the South Pole along the Greenwich Meridian, at 90 degrees angle of the Equator. It completes its journey in 14 hours. With the rotation of the Blue Planet from West to East and with the movement of the Polar Satellite from North to South, the Polar Satellite is thus capable of scanning the whole surface of the Earth and gather all information required. It then feeds the Geostationary Satellite which in turn processes the data and information and sends it to Meteorological and other stations on the ground. 

   The Geostationary Satellite sends imageries of the atmosphere to the Weather Stations situated on the ground. The imagery that is received depicts a certain zone of the Globe as seen from the space. This area is called Footprint. Each Footprint depends on the area that the country or the institution desires to obtain. So, the Meteorological Services of Vacoas receives the Footprint of part of the Indian Ocean. This Footprint depicts the clouds, depressions, or atmospheric disturbances of the region found between Latitudes 40 degrees East to 90 degrees East and between Longitudes 0 degrees South (the Equator) to 40 degrees South. The scientists working with the Satellite, also send other information like cloud formation, sea surface and land surface temperature, wind direction and wind intensity including lots of other data.
