[Via Satellite 09-16-2016] Satellite manufacturers anticipate that flexible, software-defined spacecraft will be easier to produce than today\u2019s highly specialized units, which is good because manufacturers don\u2019t expect the same business models that work today are going to last much longer in the future. At World Satellite Business Week\u2019s \u201cSatellite Manufacturing: Evolution or Revolution\u201d panel Sept. 14 in Paris, the general consensus was that the industry is currently in the midst of an evolution that is escalating into a full-blown revolution regarding how satellites are made.<\/p>\n
In general, manufacturers spoke with unanimity on changes like the gradually increasing use of additive manufacturing, the optimization and consequent adoption of electric propulsion, and the implementation of \u201csmart factory\u201d techniques. The big change, or \u201crevolution\u201d most expect is for digitization to prompt a major shift in the way satellites are built and used.<\/p>\n
\u201cWhat\u2019s interesting about the digital, or flexible payload, is as more capability is provided, they become simpler to build,\u201d said Mark Spiwak, president of Boeing Satellite Systems International<\/strong>. \u201cThere are less parts, there is less complexity, and that reduces cost.\u201d<\/p>\n Spiwak said it should not be a surprise to anyone that customers don\u2019t want stranded bandwidth anywhere, but would rather have flexible payloads that allocate in-space resources according to customer needs. Describing the industry as \u201cripe for digitization,\u201d he said operators desire the ability to put bandwidth where it\u2019s needed, when it\u2019s needed, and affordably to boot.<\/p>\n Boeing now has two commercial satellites, Intelsat<\/strong> 29e and 33e, with in-orbit digital payloads, and another recently ordered for startup Global<\/strong> IP<\/strong>, which Spiwak said would feature the company\u2019s seventh generation digital payload, offering twice the capability of generation six.<\/p>\n Though long the desire of operator CTOs, flexible satellite payloads have remained elusive until recently. Satellite manufacturers are now looking at flexible satellites as a win-win for both operators and builders of satellites.<\/p>\n \u201cWhen we started looking at the flexible payload, or software-defined payload, we looked at those not necessarily as a way or a tool to improve the performance of the satellites and the payloads onboard the satellite. We started looking at these as a means to reduce schedule by 50 to 60 percent and reduce costs by about the same amount,\u201d said John Celli, president of Space Systems Loral <\/strong>(SSL). \u201cWhy? Because a software-defined payload allows you to build repeaters to inventory.\u201d<\/p>\n Celli described future satellite procurement as potentially similar to purchasing a car, where operators could look at available options, choose what they want, and purchase something that best fits their needs. The ability to program a payload both before and after launch, allows payloads to be built en masse at a low cost, he said. This, along with a new initiative at SSL to create more \u201coctagonal\u201d satellites that better match the space within cylindrical rocket fairings, are efforts by the company to make more capable satellites, which Celli said industry desperately needs.<\/p>\n \u201cThe technology is changing, and for our customer to wait three years for a satellite, and then make the commitment for 15 years \u2014 which is really done only because their board requires a certain Return on Investment (ROI) \u2014 it wont be possible anymore. There are other dynamics that are going to come into place,\u201d he said.<\/p>\n Frank Culbertson, president of Orbital ATK<\/strong>\u2019s space systems group, echoed a similar point saying satellite operators are under a lot of cost pressure from not only industry competition, but also from terrestrial players.<\/p>\n \u201cWe are seeing that the quicker we can get a satellite to orbit, the more competitive we can be and the more responsive our customers can be. So working on ways to shorten timelines from a Request for Proposal (RFP), and not just the discussion part but the actual execution. I think you are going to see that throughout the industry where people are competing not just on cost but on time,\u201d he said.<\/p>\n Jean Luic Galle, president and CEO of Thales Alenia Space<\/strong>, said High Throughput Satellites (HTS) will probably be the main trend driving growth in the satellite manufacturing business in the future. This includes Very High Throughput Satellites (VHTS) and other powerful assets such as future terabit level spacecraft. To get there, he said flexible payloads will be key.<\/p>\n \u201cSo what are we working on? Very simply: software. I\u2019ve been working in a lot of high tech industries, and satellites are one of the last objects \u2014 very high tech, very sophisticated \u2014 where hardware has the main importance compared to software,\u201d said Galle, adding that most of Thales Alenia Space\u2019s recent hiring has been from the software field.<\/p>\n \u201cIt used to take many years to develop digital processes and then they would fly for 15 years \u2014 that is gone. We need to be developing digital processes much faster,\u201d added Arnaud de Rosnay, SVP of telecommunications satellites and space systems at Airbus Defence and Space<\/strong>. De Rosnay said Airbus Defence and Space is seeing digital processing increasing across many programs, yielding improvements like reducing time for testing. He described Eutelsat<\/strong> Quantum, the company\u2019s first software-based satellite design, as a \u201cSwiss Army Knife\u201d style satellite capable of changing coverage, band or power at will. Airbus subsidiary SSTL<\/strong> is building the platform, with support from the European Space Agency<\/strong> (ESA) and the U.K. Space Agency<\/strong>.<\/p>\n Lockheed Martin<\/strong>, which began an extensive overhaul of its flagship satellite bus, the A2100, in 2013, is also adding new flexible on-board processing capabilities to commercial satellites. Scott Lindell, VP of strategic planning for commercial space at Lockheed Martin, said the company is focused not only on making its satellites much more capable in putting capacity where it is wanted, but is also making extensive strides to bring ground segment technology up to par with the space segment side.<\/p>\n \u201cWe tend to focus on the re-programmability of the satellite, but it also requires a capability on the ground and overall architecture to take advantage of that,\u201d he said. \u201cThat\u2019s not only what we do with the payload that\u2019s on the satellite but what we do with the ground segment in how we manage the satellite and a constellation of satellites. It\u2019s really becoming more end-to-end architecture flexibility as opposed to one key element of it.\u201d<\/p>\n Lindell said Lockheed Martin has reorganized its internal structure to bring the ground segment and space segment elements into one organization to help enable the architecting of end-to-end solutions.<\/p>\n","protected":false},"excerpt":{"rendered":" [Via Satellite 09-16-2016] Satellite manufacturers anticipate that flexible, software-defined spacecraft will be easier to produce than today\u2019s highly specialized units, which is good because manufacturers don\u2019t expect the same business models that work today are going to last much longer in the future.
