Satellite Resilience: Future-Proofing Space Systems #shorts

There's first aspect is resilience. So, the trend goes to to like having multiple orbits, multiple frequency bands, and not just buying from one vendor. So, you will buy your user end devices from not just one vendor. You will not just one use one satellite network to get your your internet connection. You'll have multiple. And the receivers will very likely in the future support multiple Swiss standardization like 5G NTN for example. Uh for the user second, we have OSNMA, which is now becoming operational. So, this will be an authentication service for GNSS signals. So, basically they send you on a separate channel a fingerprint for GNSS signals so you cannot be spoofed. Um or you can at least detect when

someone tries to spoof you because it's it's not matching the fingerprint. And for the space segment, like I said earlier, so you can of course someone trying to to shoot a rocket at you or or try to grab your satellite. So, they're adding more maneuverability to the systems. Um same goes for electronic warfare. So, they they try to be more resilient to to jamming attacks. Also using like laser communications, which is a lot more directed and a lot more difficult to intercept or to attack. And active sensor protection systems. Um what what we see is an increased like use of cloud services. Also like the big providers like uh Microsoft and also um Amazon. They have their own ground

station network, which you can access actually as like an AWS ground station service. So, they have like sites around the world where you can subscribe to. Um This is like this ground station as a service concept. Um Another thing which was previously burned into the spacecraft is the software. Um now with more powerful onboard computers, it actually becomes more configurable. And now often actually users can run sandboxed applications on spacecrafts directly. So, this is used for example for edge processing. So, if you take an image of the surface of Earth and you have cloud coverage above 80% um you might want to discard it. So, there is like image processing going on onboard and all these custom

applications. Um which again introduces some risk because now you have suddenly software from some someone else running on a spacecraft. And then we have the the the quantum and crypto things uh which are slowly coming. So, especially for the governmental side of things, they are very interested in post quantum quantum cryptography, crypto agility, so so the buzzwords. But, this is far from reality. So, this is in the in the very early stages.
