LEO Capacity Customers Discuss New Applications

LEO

Everyone is talking about the Low Earth Orbit (LEO). To say it is the hot topic of the industry is the understatement of the year, and this is all before we hear about SpaceX’s definitive plans for StarLink. SpaceX has been vague about Starlink so far, but knowing SpaceX, it is unlikely to lack ambition — particularly if people are working 80-hour weeks to make it happen!

It is impossible to predict how many LEO satellites will be launched over the next few years. But, it is safe to say it will be in the thousands rather than hundreds. Huge numbers of satellites are going to come online. The question is, with all this capacity coming online, who are the customers going to be? What are the applications that will drive LEO take-up?

What are the markets for LEO satellite capacity? We can talk capacity of satellites, the numbers of satellites, but ultimately, the satellites are only as good as the customers which want to buy capacity. Mobile backhaul, global connectivity including cloud access, emergency services, and disaster recovery are examples of verticals that will be addressed by LEO satellite services. It is important to recognize that the government satellite market when served by advanced LEO constellations, will likely grow far larger than it is today. The expanded government market is expected to include civilian services including digital inclusion, diplomatic communications, and border control and protection as well as highly reliable broadband for military and defense — global broadband that will deliver greatly improved resilience, speed, and security in support of defense missions around the world.

The Internet of Things

IOT can mean different things to different people, and where satellite fits in has been the subject of much discussion over the last few years. It is particularly relevant to satellite operators in the LEO space. Osborne says that IOT is interesting and different from traditional telecommunication services, as the majority of the value does not lie in just providing connectivity — it is derived from the additional services that are layered on top. He says this could include application-specific data analytics and hardware, security features, cloud compatibility, as well as installation and maintenance of hardware. “Satellite operators provide connectivity as their core, but there is a lot of flexibility to move around in the value chain to deliver these additional products and services,” he says. “For Kepler, we are initially focusing on the user hardware as well as the connectivity part of the value chain. In other words, we sell connectivity hardware and airtime. Our fundamental belief here is that by tightly integrating these two critical components and developing them in parallel, it will give us a compelling value proposition that will allow us to later move on to other portions of the value chain.”

Hudson says Telesat believes the IoT market today is more about potential than opportunities that will drive near-term satellite industry revenue. “As IOT visions such as “smart cities” and autonomous vehicles become more widely deployed, high performing LEO constellations will be a cost-effective way to connect devices, sensors, monitors and controllers to the global internet cloud. We also expect many IOT customers to aggregate data from a number of IoT devices at a single satellite terminal for simple and low-cost connectivity into our LEO network,” he adds.

In the coming years, Hartin believes satellite IOT customers can expect to see small data modems capable of broadband speeds that can be easily embedded into any application, vehicle, machine, device or ‘thing’, which is going to be particularly important for Unmanned Aerial Vehicle (UAV) command and control type applications. “Most importantly, customers can have the peace of mind that their assets will remain connected anywhere on the planet,” he says.

Impact on GEO

With the satellite industry moving to a more data-focused world, one of the other big questions is how LEO and GEO satellites will co-exist in this new world, and how the applications will be mixed between the different satellite assets. Osborne says it is unlikely that LEO will be the orbit of choice for most data applications. As mentioned, the ground equipment characteristic will give GEO satellites a competitive advantage for many fixed applications, with LEO having performance advantages for mobile. “What will be particularly interesting in my view is the effect on bandwidth pricing should mega LEO constellations come online,” he says. “Consider that the jump in globally available bandwidth from 500 Gbps to 1 Tbps by the introduction of High Throughput Satellite (HTS) systems has plummeted prices to 30 percent of what they were a few years ago. Mega LEOs are promising 10s of Tbps of capacity, and this will have a profound impact on bandwidth pricing as well as business cases for these operators. Ultimately, the immutable laws of supply and demand will prevail!”

Hartin believes LEO will definitely dominate in remote areas, like the polar regions, especially in verticals like maritime, where reliable and available connectivity is paramount. He also believes that GEO VSAT will continue to reign strong in the higher bandwidth space. “It will be interesting to see what the likes of OneWeb and SpaceX’s Starlink constellation will do to that existing dynamic. A lot of new HTS capacity is planned to come from GEO, but now also some from LEO. We don’t have a dog in that fight because we’re in the L-band and focused on specialty broadband versus commodity broadband, specifically, but we’re as interested to see how it shakes out like everyone else,” he says.

Outside of those traditional markets, Hartin thinks LEO opens the door for many future and unique innovations. “I think with the rise of proposed constellations, we will see a rise in LEO satellite-connected-devices as well across the board.,” he says.

So, therefore it is in a great position to assess the merits of both orbits and how it will impact its business going forward. “We believe LEO satellite services will be transformative for two-way data applications. The capability to reliably connect from anywhere to anywhere, with low latency, high speeds and at low cost, is a very compelling value proposition for new LEO constellations. GEO satellites will continue to play a role in broadcast services and for consumer broadband given the huge investments made in GEO HTS platforms to serve consumers. As LEO networks mature and as LEO ground terminals become lower priced, we expect LEO satellites will also be an attractive option for high-quality consumer broadband,” Hudson says.

Examples of LEO in a Mobile World

Mobility, whether connected ships, planes, or cars, has long been targeted by satellite players as they look to diversify their revenue streams. However, where does LEO fit into some of the mobility markets, and are there examples that LEO players can learn from? Osborne talks about a specific example in the maritime sector, where it is deploying its services on icebreaking vessels, such as the German Polarstern vessel, which spends the bulk of its operating lifetime outside of GEO coverage. He says what is important to remember is that it is difficult to learn about the market and about customers until you try and deploy a service. “This is why we opted to deploy our service as soon as possible. For instance, in deploying our service to vessels, we learned that deck space was a major challenge; vessel operators do not have deck space for additional antennas. If an LEO system requires three antennas versus two needed for GEO, that vessel simply cannot deploy an LEO service. This is a simple example, but it illustrates the point that lots of satellites are not needed to test out a market and learn about customers. Ultimately, failure to learn about a market will doom many large LEO projects,” he adds.

Rigolle when looking to give an example of how LEO satellite could be used talks about the provisioning of lowest latency links to the financial services industry. “Never before has that been done on anything other than subsea cables for transcontinental connections, now that will move to satellite. The ability to operate oil rigs from shore using the near real-time command and control capacities is another.
