With a digital and mobile revolution already
in full force across the African continent, satellites and who is in
control of them are becoming increasingly important.
South Africans are leading the way with
their National Space Agency (SANSA) operations in Hartebeesthoek,
Gauteng. With an antennae farm of over 22 antennae and orbcomms, as
well as a mission control centre and operations room tracking and
downloading satellite data, the facility is designed to grow. SANSA
is currently assisting the Ghanaian government to re-purpose an old
mobile-phone facility, in Ghana's first steps towards participation in
the African space race.
Matloop is a polyvalent wireless
communicatio, or PWC, system. This is a system that allows the
simultaneous provisioning of telephony, internet and video services
from a satellite broadband connection without using any landline cable
such as fiber optics. Dr Victor Agbegnenou wants to keep his
invention in the hands of Africa and believes it should be delivered to
the continent without the intervention of large Western technology
companies.
His PWC system is being tested as a way to connect
medical laboratories throughout the continent. Agbegnenou is Togolese
but based in Paris, where he has gathered a large community of
scientists from the diaspora who are all committed to finding ways of
implementing the PWC technology to solve a number of African problems.
Dr Sandile Ngcobo has found a way of controlling the shape of the light coming out of a laser - something previously thought to be impossible. With his discovery, laser beams can be digitally controlled from inside the laser device itself. His work is talked about as a "disruptive innovation", something which turns previous scientific ideas upside down. Scientists liken his invention to the actual discovery of the laser 50 years ago. Now that it is possible to manipulate the light in this way, scientists believe that applications will be found in areas like medicine and manufacturing.
