According to the latest Euroconsult report, the global satellite industry is now on course to build and launch some 17 000 satellites over the next decade. The next ten years will see a race to deploy the first mega-broadband constellations, plus a new constellation for real time earth observation. What implications will these developments have for the African market?
1700 satellites per year for 10 years
The Euroconsult satellite market forecast, individually assessed around 170 constellation projects of which 110 originated from commercial companies. While OneWeb, Starlink, Gwo Wang, Kuiper and Lightspeed will collectively account for some 58% of the anticipated 17,000 satellites to be launched, these leading firms will only contribute approximately 10% of the total satellite manufacturing and launch revenues of the space industry. According to the report, two key reasons combine to explain this disparity. The first is the economies of scale inherent in satellite manufacturing, and the second is a marked decrease in launch prices.
In their follow-up annual Space Economy Report released in January 2022, Euroconsult estimated that the global space economy in 2021 totalled some $370 billion. This figure includes commercial space revenues and government procurement of $337 billion, in addition to $40 billion from governments for internal costs and R&D.
Opportunities for Africa
Adding 200Tbps of Capacity
According to GMSA, by the end of 2022, 495 million people will be subscribed to mobile services in sub-Saharan Africa – some 46% of the region’s population.
It is expected that the New Space satellite constellations will add a total of 200Tbps capacity to the sub-Saharan African market. To put this in context, the Seacom undersea cable was designed for 12Tbps and is currently provisioned at 500Gbps, so satellites have the potential to add the equivalent of 16 additional Seacom cables. Adding to this are the fundamental benefits of satellite services, including the fact that they are immediately available, anywhere and everywhere. This means that Africa could soon experience a capacity burst in the market, and all the advantages that will flow from that.
No-limit Connectivity
For example, Starlink is promoting service rates of 50 – 150Mbps, with latency of just 15-100msec at monthly charges of $100, which appear to be more targeted towards professional users rather than the general consumer market. OneWeb is clearly more of a B2B offering with latency of just 70msec and data rates of 300Mbps. Completing the current range of offerings, mPower MEO service will provide very high capacity 400Mbps point-to-point links at 150msec latency, making a viable alternative to fibre connectivity.
Conclusion
The planned 400% increase in satellite launch activities over the next decade will transform the global telecoms industry by adding 200Tbps capacity to overall network fabrics. While the majority of services and developments are focused on Government applications, Africa certainly stands to benefit from this expansion.
