YELLOWSAT, French supplier of inclined-orbit-satellite capacity an exhibitor at AfricaCom

ELLOWSAT is a Paris-based high-tech company specialising in providing dedicated broad- band satellite links. They have


developed a proven powerful technology that allows the large users to use a scarcely tapped satellite resource, the inclined- orbit satellite capacities. Based on that technological break-


through, the Company offers its services to companies, telecommunication providers, and government institutions in partner- ship with major satellite communication providers such as SES.


YELLOWSAT has developed a technology to offer inclined-orbit satellite-based telecommunications that are both cheap and reliable.


7 to 10 years after launch, a fixed-orbit


geostationary satellite cannot perform all the space stabilisation manoeuvres anymore because of fuel lack. The satellite operator can then decide to change the way it handles the resource, and in consequence the orbit becomes inclined. With half less manoeuvres (and hence fuel consumption), the satellite keeps its geostationary position, but its trajectory exhibits a gradual tilt vs. the equatorial plan, hence the ‘inclined orbit’. The advantage is that the satellite op- erational life is increased significantly, even by 6 to 8 extra years sometimes. However, until today, inclined-orbit satellite trajec- tory could only be tracked in a partial way and thanks to expensive investments with large dish station. Only large links (over 20 Mbs) have been in use. “The operator generally only books 20% of the capacity of their inclined-orbit satellites” states Pierre GRENIER, Co-Founder and CEO of YEL- LOWSAT, “the inclined orbit is mainly an untapped resource, especially for smaller- sized links, from 1 to 20Mbs for instance”. YELLOWSAT has developed a propri-


etary technology that enables the reliable continued use of the satellite in «inclined» mode thanks to a tracking system on the ground. That system is coupled with standard market products to make up for a complete satellite station. Tracking is


achieved thanks to algorithms developed by YELLOWSAT, an approach which has proved to be extremely reliable and autonomously forecasting geostationary satellite trajectories, thus guaranteeing the same quality of service as a fixed orbit satel- lite. “Everybody thought that reaching such results would be impossible, but we proved them wrong!” says Daniel TITS, Co-Found- er and R&D Director at YELLOWSAT. Mr. TITS is a former EUTELSAT R&D and operations executive, with over 30 years of experience. YELLOWSAT technology also enables


any geostationary satellite, whether in fixed or inclined orbit, to be seamlessly and remotely accessed in maximum 4 minutes, and satellite life to be extended. The system has been thoroughly tested


by industry expert public and private organizations. In particular, YELLOWSAT has been granted accreditation by ESA, the European Space Agency. Thanks to that proprietary technology,


YELLOWSAT can offer affordable dedi- cated broadband links of any size to any organization, all over the world, and especially in countries where the fibre net- work infrastructure is not fully developed, as well as backup for existing links.


Showcase: with their SES partner, YELLOWSAT provide Congo Brazza- ville with satellite communications


Since 2011 YELLOWSAT have been pro-


viding the Republic of Congo’s Ministry of Infrastructure, Public Works & Recon- struction with their service and system, which beams over the whole zone, and at a bandwidth price much lower than with existing fixed orbit. “SES are constantly trying to cus-


tomise capacity for their customers. By providing inclined capacity over Africa, we are meeting our customers’ requests for affordable solutions», says Simon GATTY-SAUNT, VP Sales, Europe and Central Asia, at SES. «We are delighted to count YELLOWSAT among our customers. Their arrival reinforces our commitment to provide Internet connectivity to end-users


on the African continent, and let us intro- duce our orbital position of 47 °West”. In partnership with the satellite operator


SES, which provides the initial satellite com- munication, YELLOWSAT also provides enterprises, governments and institutions in Africa with Internet connectivity.


Inclined orbit represents the future of African satellite telecom


YELLOWSAT has chosen AfricaCom


as their first international trade fair to communicate. YELLOWSAT are provid- ing an update on their activity, confirming that their system is perfectly operational and ready for sale. In 2012, the Company received equity backing from the Magellan Industries-managed funds, also share- holders of the airplane manufacturer LH Aviation. Those financial resources will help YELLOWSAT launch their service internationally and industrially, and meet the market needs. The Company targets in particular Afri-


can countries, which are perfect matches for their inclined-orbit offer. Compared to West European countries, they still suffer from a partial lack of ground infrastructures and thus from a higher bandwidth price. “Com- munication is a universal human need, but inequality in infrastructures still remains” says Pierre GRENIER. For a number of years


YELLOWSAT are the ONLY ONE that can help you safely use satellites via in inclined orbit at an affordable price: 50% less cost, 100% performance. YELLOWSAT full system (dish + monitor-


ing, based on standard hardware) is easy to deploy, easy to maintain, and autonomous. With YELLOWSAT, you can connect the last mile to backup links. YELLOWSAT’s main partners are SES, INTELSAT, MEASAT, ABSAT, CASTOR NETWORK, and the European Space Agency (ESA).

satellite has been an alternative to the heavy investment required by fibre use, especially in isolated regions. However the price of satellite bandwidth is still too high for some specific zones to be connected. “From now on, with YELLOWSAT and their partners, the satellite can beam over any area affected by the digital divide in an economically viable way, whether sparsely populated or not. Our goal is to help mind the digital gap in Africa” says Pierre GRENIER.
