SMM proposes the launch of one or more small-class geostationary satellites, featuring Ka-band spot beam payloads, in order to reduce satellite broadband service costs by an order of magnitude and bring them into line with terrestrial offerings. The system is intended to serve markets that do not have access to existing terrestrial infrastructure, providing considerably more capacity at lower cost than current systems.
By launching a low cost, lower capacity satellite to stimulate the market, initial capital expenditure costs can be kept to a minimum while capability is matched to demand. As the speed of market growth increases, further spacecraft can be added to the constellation, culminating in the launch of one or more large spacecraft later in the mission. This gives operators time to grow their business, test market predictions with low risk, not have expensive satellite capacity sitting idle in early years and to develop more complex and technically capable large satellites over a longer period of time. By taking this approach, the operator can quickly reach profitability, even during the initial low growth period expected when starting such a service.
Broadband internet access in Europe today is a case of "haves" and "have-nots" the so-called "digital divide". In the west, many rural areas or fringe coverage areas can get no broadband or only limited speeds. In the east and south of Europe, large areas of both rural and urban populations cannot get any broadband access.
Operators need a different approach, in order to test the market and minimise the amount of capital that has to be tied up in on-orbit hardware. The typical growth pattern for this type of service is the "S curve", starting slowly the growing rapidly during the middle phase of the project and finally tailing off again as the market becomes saturated. Large satellites are ideal for the middle high-growth phase, but are vastly over specified for the expected first two or three years when growth is slow.
Small satellites, such as SMM, provide a means to exploit cheap launches and lower costs, in order to provide a more affordable solution that will reduce costs to the operator and consumer. This will finally reduce service costs to a point where we get mass market take-up, breaking the stalemate of high prices and low economies of scale present in today's two-way satellite broadband market.
SMM offers potential operators the ability to tailor the size and therefore cost of their service to the size of the market. A small initial investment allows low risk and rapid return, a model that should prove more attractive to the service provider and allow savings to be passed on to the consumer.
By deploying multiple spot beams across Europe, an order of magnitude more capacity can be expected from the SMM system, rising again later in the mission when larger spacecraft are deployed. The spacecraft will be designed from the ground up for broadband - using Ka-band to enable large bandwidths to be employed, spot beams to reuse that capacity efficiently and enable compact user terminals, multiple transponders on a small platform to enable low cost of entry and highly automated management systems to enable low operating costs.
None of SMMs existing or planned competitors that we are aware of can offer all of this. Rather than up to Â¬300 per month, target residential costs will be less than Â¬30 - finally bringing services comparable to terrestrial broadband at comparable prices. All European residents and businesses will have similar services available to them, no matter where they live.
The baseline is to launch two spacecraft covering 80% of Europe. The first spacecraft, proposed to be launched in mid-2007, will cover the priority markets (high need, high willingness to pay) of the UK, Ireland, France, Italy and possibly Turkey, the Czech Republic and Hungary. Twelve months later, a second satellite will be launched to fill in gaps in the coverage and bring the service to the vast majority of the European population. Both use 8 beams with 16 forward link DVB-S2 carriers to produce a total throughput per satellite of almost 1Gbps (Gigabit per second). Pending a successful first period of operations, further small or medium-class platforms may be launched to boost coverage in high-demand areas.
The SMM study is investigating many key issues relating to today's high cost of satellite broadband internet access. The study has addressed service types, key markets, reduction in the cost of the space segment, reductions in the cost of launch, requirements for the ground segment and commercial viability of the project.
The SMM partners have to date investigated all areas concerning market research, commercial viability, ground segment design, space segment design, launch vehicle availability and mission operations.
