Most industry observers would argue that big remains beautiful in satellite manufacturing, especially for commercial applications in mobile satellite telephony and broadcasting. At the same time, however, operating needs and budget pressures facing government, military and civil users are pushing many of them towards small satellite platforms.<\/p>\n
Add the wonders of miniaturization of electronics witnessed in recent years and the picture is complete \u2014 the success enjoyed by satellite manufacturers such as Orbital Sciences with its Star Bus spacecraft for Geostationary Orbit (GEO) is a clear example of how small satellites are emerging as crucial tools in a renewed global space race. An increasing number of countries joining the league of space-faring nations through programs focused on the development, manufacturing and launch of small spacecraft.<\/p>\n
\u201cOver the last few years, we have seen countries not just wanting to use space applications, but also intending to understand the technology behind them,\u201d says Werner Balogh, a program officer for the Basic Space Technology Initiative program of the United Nations Office for Outer Space Affairs (UNOOSA). \u201cIn this sense, small satellites programs are of paramount importance for capacity-building in space technology development in these countries.\u201d<\/p>\n
Commercial demand and government-driven programs are energizing this market segment, however, the evolution of demand for small satellites depends on how you define small satellite over time, says Rachel Villain, director for space at Euroconsult. \u201cBased on our studies, adding the backlog of small satellites currently in construction to the 274 units that have been launched over the past decade gives us a total of 352 satellites over 15 years. This is around 23 units per year, with the definition of small satellites as launch mass of between 10 and 500 kilos, destined for any orbit.\u201d<\/p>\n
Villain\u2019s figure excludes the three Low Earth Orbit (LEO) constellations Orbcomm, Gonets and the first Globalstar generation, which would together add another 100 spacecraft to the total. When confronted with these numbers, one could make an observation that activity around small satellites has remained strong in recent years. But, it is even more interesting to see who is commissioning these satellites.<\/p>\n
According to Euroconsult, most small satellites are built for government clients including the academic world. \u201cOver three quarters of the 352 small satellites launched and to be launched are requested by the civilian and military agencies of various governments around the world,\u201d says Villain. \u201cWhen small satellites built by academic institutions are added, the total grows to 91 percent with only 9 percent left for commercial companies.\u201d<\/p>\n
As to where demand is coming from, the United States is the dominant force in this sector, with a 30 percent share due to high-demand from NASA and the Department of Defence (DoD). Europe enjoys a 25 percent share, while Asia follows suit with 22 percent thanks to activity in China and Japan. Russia has a 13 percent share of the market, while the Middle East and Africa (MENA) tops 9 percent and the rest of the world follows with 5 percent.<\/p>\n
\u201cIt is interesting to observe how the Middle East and Northern Africa is emerging as a region of interest for small satellites, while Latin America remains a limited market,\u201d says Villain.<\/p>\n
There are certain applications that seem commonly well suited to small satellites: in-orbit technology demonstration and testing; Earth observation; and space science. Together, these three examples dominate 80 percent of the application environment, portraying a clear indication of an increasing number of countries entering space.<\/p>\n
\u201cMany countries use small satellite programs to qualify and demonstrate their technology and engineering capability, often through academic institutions,\u201d says Villain. \u201cFor example, in Saudi Arabia the Space Research Institute of the KACST (King Abdulaziz City for Science & Technology) builds two series of satellites \u2014 the SaudiSats and SaudiComsats.\u201d<\/p>\n
Through this approach, countries are aiming to qualify basic space capabilities to build more powerful satellites in the future. For example, the first generation of 10-kilogram Saudisats were designed to provide store-and-forward communications and carry out space experiments. The 200-kilogram Saudisat 3, on the other hand, is reported to be equipped with a payload dedicated to Earth observation. Technology and Earth observation applications for small satellites seem to enjoy the strongest growth historically, while communication remains a small segment. Science also is a small segment, remaining concentrated to a limited number of countries.<\/p>\n
More than 90 percent of small satellites are sent to a LEO orbital location. Most of these go in non-Sun Synchronous Orbit (non-SSO) missions, though growth in SSO is being witnessed. \u201cStrong growth of SSO satellites is due to the multiplication of Earth observation missions for countries already active, for example, the United States, Israel and Europe, or for emerging countries,\u201d says Villain.<\/p>\n
Traditionally, satellite manufacturing has been the domain of a handful of large aerospace companies from technologically advanced countries and regions such as the United States and Europe. Small satellites, however, are bringing about major changes to this world order, as an increasing number of developing countries are entering the space sector.<\/p>\n
\u201cIn the past, satellite technology was an extremely specialized field,\u201d says Balogh. \u201cToday\u2019s micro- and nano-sats make heavy use of off-the-shelf components that are also used in consumer technology. Engineering knowledge and work experience gained in small satellite programs is therefore often directly transferable to other technology fields.\u201d<\/p>\n
This is also having the effect of widening the pool of manufacturers and creating opportunities for emerging companies. Smaller satellite manufacturers such as theUnited Kingdom\u2019s Surrey Satellite Technology Ltd (SSTL), now a subsidiary of EADS Astrium, and Germany\u2019s Orbitale Hochtechnologie Bremen (OHB) are leading the way.<\/p>\n
\u201cWe see a growing demand at the \u2018top end\u2019 of the small satellite product range where customers are procuring small satellites for operational reasons to do missions that in the past would have been the domain of large satellites,\u201d says Phil Davies, SSTL\u2019s business development and sales manager. \u201cFor example, take very high-resolution imaging satellites such as those that can image at one meter or better resolution. In the past, these would typically cost several hundreds of millions of dollars. Due to the massive improvements in technology over recent years this class of mission is now capable of being performed by small satellites such as the SSTL-300 series for tens of millions of dollars.\u201d<\/p>\n
The other massive growth area is that of very small satellites \u2014 nanosats and cubesats. While the capability of these satellites is still generally below what is needed for most operational missions, they can be implemented at an extremely low-cost and are becoming widespread for educational missions, says Davies. Opportunities for these satellites are coming from regions such as South America, the Middle East, Asia and Africa, with countries like Nigeria and Algeria leading the way in Africa \u2014 areas without long standing space programs. \u201cThis summer Nigeria will launch its second and third Earth observation missions, which have been built in collaboration with SSTL and are designed to deliver information to help Nigeria manage its resources, improve its agriculture and map the country, as well as providing a platform for the development of a high-tech and high-value indigenous skill base,\u201d says Davies.<\/p>\n
In July 2010, SSTL started building a small satellite for the Republic of Kazakhstan to provide medium resolution, multi-spectral EO capability to complement the high-resolution satellite built by EADS Astrium. Germany\u2019s OHB is also making significant inroads in the small satellite market, with programs like the SAR-Lupe for the German Armed Forces. Under its lead management, OHB is developing a European Small Geostationary (SGEO) platform for communications applications to be marketed commercially under the name Luxor. OHB is acting as contractor general for the project, which last year was estimated to be worth 566 million euros ($811.65 million). OHB will provide the satellite platforms, while SSTL will supply the payloads for the satellites. The launch of the first two satellites is scheduled for the end of 2012. <\/p>\n
Small satellites are once again playing a crucial role in promoting access to space and satellite applications for developing countries, according to Balogh.<\/p>\n
\u201cThe desire to close the gap between countries with space capabilities and those that did not have access to space applications and technology was addressed in 1971 with the establishment of the UN program of space applications. In 2007, we came up with the Basic Space Technology Initiative to fulfil our mandate with capacity building in member states that desire to establish basic space technology development capabilities,\u201d he says.<\/p>\n
On the satellite side, more and more mission types are being developed to provide support to valuable applications, opening opportunities for instrument builders, subsystem suppliers and other supply chain elements. The road to space through small satellites, however, is not completely smooth. Factors such as launch costs, debris creation and competition from hosted payloads applications, are also to be considered across the whole satellite value chain. Cost-effective launches remain important, as small satellites are still penalised in comparison to larger platforms when it comes to launch costs per kilogram of mass.\u201cThe main trend we see in imaging missions is the ever increasing demand for very high resolution data \u2014 the world\u2019s appetite for such data seems to be growing exponentially. We also see small satellites moving into other areas which have been the domain of larger satellites until recently, for example, radar missions can now be supported through small satellite solutions such as the SSTL NovaSAR (synthetic aperture radar) system,\u201d says Davies.<\/p>\n","protected":false},"excerpt":{"rendered":"
