Next week leaders from across the space industry and governments around the world will convene in London for the 2024 Defence in Space Conference to tackle the most pressing space-based threats and challenges that global militaries face today.

Ahead of the event, the Government Satellite Report had the opportunity to sit down with one of the conference speakers, Juliana Suess – a space security Research Fellow on the Royal United Services Institute’s (RUSI) Military Sciences team and host of the podcast War in Space.

During our discussion, Juliana delves into the current state of the space threat landscape, as well as the role SATCOM and multi-orbit capabilities are currently playing in military operations today, and pulls back the curtain on some of the expected trends and hot topics that will take center stage at the event.

Government Satellite Report (GSR): What does the space-based threat landscape look like for today’s militaries?

Juliana Suess: When we examine the counter-space weapons landscape, there is a whole host of different capabilities that range from temporary and reversible measures to the non-reversible and permanent damage end of the spectrum.

Though space has become increasingly contested within the last few years, I think what we’ve been seeing are counter-space attacks that fall on the temporary and reversible range in the electromagnetic spectrum or the cyber sphere, though kinetic tests against states’ own assets have also taken place.

GSR: What impact is SATCOM having on multi-domain military operations today? 

Juliana Suess: SATCOM is a key enabler for all operations. I think quite often there’s a misconception that space is an add-on luxury that militaries can begin to afford once everything else is in order. In reality, space-based capabilities are a requisite, because we need SATCOM as part of a military’s daily operations.

If we look at the UK Space Power doctrine, not only does it already state that the vast majority of operations couldn’t be sustained without space, but it also goes on to say that SATCOM is responsible for all beyond-line-of-site communications. So, whether it is an aircraft or a vessel at sea, all multi-domain operations are made possible through satellite communications.

Space is a connector. Without the information and data that we receive through SATCOM and space, a lot of modern military operations simply wouldn’t be possible.

GSR: What benefits are multi-orbit SATCOM capabilities providing to military operations today? 

Juliana Suess: Resilience is a key aspect as it pertains to multi-orbit SATCOM. For example, if an orbit was compromised through a Kessler syndrome-type event or through a large-scale attack on satellites that would make part of an orbit unsafe, having the resilient capability of migrating service to a different orbit and using those satellites is tremendously impactful.

There’s also a utility aspect in these orbits to be considered. For example, Low Earth Orbit (LEO) has very low latency. Communications that don’t have to be classified or tightly secured can leverage a commercial provider in LEO. Whereas more highly secure communication channels can then be reserved for the assets that sit in Geostationary Orbit (GEO).

GSR: What are some of the challenges, needs, and requirement trends you’re seeing from militaries as it pertains to satellite capabilities? What gaps still need to be bridged?

Juliana Suess: In the UK, we have SKYNET – our sovereign satellite communications program which covers a lot of the required satellite capabilities that we need. But when we specifically look at Positioning, Navigation, and Timing (PNT) and Intelligence, Surveillance, and Reconnaissance (ISR), the UK is still very reliant on the U.S, although at least some of those gaps could be bridged with commercial partners.

I think the challenge overall – and the UK is not unique to this – is just money. Space is expensive and space-based projects take a long time. For example, the UK could no longer be part of the EU’s Galileo space program, which is the EU’s answer to GPS. The idea was floated that the UK could build its own PNT system, but the funding aspect made it impossible for a country the size of the UK.

In terms of further trends that we’re seeing, I think resilience will be a continuing factor and consideration as we continue to build out space capabilities. That will translate to having onboard resilience elements such as inter-satellite links that allow satellites to jump over compromised ground segments. Having proliferated constellations in conjunction with multi-orbit capabilities will also be a continuing trend. Militaries will continue to not put all their eggs in one orbital basket, which will be incredibly helpful.

GSR: Next week, military and space industry leaders will convene at the Defence in Space Conference in London. What are the hot topics and trends you foresee being discussed at the event?

Juliana Suess: Since the conference will be an industry-heavy event, I think there will be a lot of discussions around the sovereign assets versus buy-in debate. The UK has put forward the Own-Collaborate-Access (OCA) framework through which it wants to view its space capabilities and the procurement of those capabilities. So, I think that’s definitely a topic that will be explored in terms of how to strike the right balance, as well as if commercial partners are brought into the fold how can they be protected from potential attacks?

When we saw the cyberattack against ViaSat at the beginning of the large-scale invasion of Ukraine in 2022, that was a commercial provider that had the Ukrainian military as one of its clients. That cyberattack highlighted the vulnerability of commercial actors, especially when they’re being used by armed forces or states.

That brings me to the next trend that I think will have a lot of discussion around it, which is how do we keep pace with the threat? I think specifically for space, we need to make a lot more consideration of horizon scanning when it comes to threats because once you put a satellite into space, it’s could be in orbit for the next 10 to 15 years.

In terms of anticipating threats that we need to protect against, we must prepare our hardware and software before launch. In that sense, space is quite unique as we must make more considerations on future protection and resilience before they even become operational.
