## Takeaways

1. Satellites need ground connections to receive commands and deliver data.
2. Launch and satellite manufacturing got faster than ground infrastructure.
3. Solving the bottleneck requires coordinating hardware, sites, networking, and software.

## About this segment

Bridgit Mendler explains why satellites need ground systems to be useful and how fragmented incentives kept that infrastructure from modernizing. Northwood chose to build the whole system to remove the bottleneck.

## Transcript

Transcribed by machine (Whisper) from the episode’s audio, so a word may be off here and there.

[6:21](https://realalpha.app/v/jHECsr9GCs8/?t=381) Yeah, I think it's been a really great experience. Let's get into Northwood, what you're trying to achieve, and what's the why now for it? Yeah. So what we do, we're ground infrastructure, kind of end-to-end for space companies. So all the way from the time when they're first coming up with satellite mission, what the space operators want to do, all the way to when they're actually streaming data, delivering that data to the end customers.

[6:43](https://realalpha.app/v/jHECsr9GCs8/?t=403) The problem that we're solving is for every satellite, it requires a connection point back to Earth so that they can control the spacecraft. It is kind of like a remote control car where it needs some mechanism to make sure that it's going where it's supposed to go and a way to actually bring that data back to the users on Earth because that's where the users are. So that point of contact on Earth is called the ground infrastructure.

[7:10](https://realalpha.app/v/jHECsr9GCs8/?t=430) And super basically, if you don't have it, you don't have a space mission. It literally is just like a rock in space you're doing nothing with. So ground infrastructure, it's completely fundamental. And for us, we were observing the space industry how launch cadence was increasing. You could put a satellite up into space way faster and you could build satellites way faster because there was this whole boom around spacecraft manufacturing.

[7:36](https://realalpha.app/v/jHECsr9GCs8/?t=456) And interestingly, what started becoming the longest pole in the tent was just getting the point of contact on the ground to connect with. So, you know, you could build a satellite and launch it faster than you could actually connect with it from the ground, which just seemed absurd. And so we're like, why is that? this kind of critical third component was not modernizing because you'd seen all this modernization happening elsewhere. And when we started pulling it back, it was kind of like a classic value chain problem where there was just not like the incentives aligned with each stakeholder in the value chain to modernize and innovate. So you had antenna manufacturers that were responding to a call from a customer and delivering them a point solution. They weren't thinking holistically about how you build better ground infrastructure. You were having like a

[8:22](https://realalpha.app/v/jHECsr9GCs8/?t=502) software integrator layer where they were basically just dependent on whatever infrastructure was being laid by somebody else. And so we realized like this is really holding back innovation and like a complete thought on what this should look like on the ground side. And so really the only way to address fixing the ground segment was to do the whole thing. And when we say the whole thing, like, it includes a lot of disparate disciplines and activities. So it includes things like R&D of antenna hardware. So the antenna on Earth that is physically receiving RF signals from space, interpreting.

[8:58](https://realalpha.app/v/jHECsr9GCs8/?t=538) them into ones and zeros, sending them back to the users, popping them back up to the spacecraft. That includes actually procuring land and doing development at a site to be able to put that antenna hardware somewhere in the world because satellites orbit the Earth. You need to connect with them as they orbit the Earth. That includes the networking layer. That includes the actual software API that you have to connect with to give commands at that ground site. And so it was kind of a daunting task. It's like realizing you have to do this really massive undertaking, this big risk in order to experience the big reward on the other side, which is unlocking this critical third pillar of infrastructure for the space economy and really enabling it to go to new heights. And so that was kind of like our venture scale problem where like this is going to require

[9:48](https://realalpha.app/v/jHECsr9GCs8/?t=588) a lot of money, a killer team across many different disciplines, and it's going to require a ton of orchestration of all of those different pieces converging together to deliver something that is really better end-to-end, as well as something that you can turn around quickly. And so that's kind of the undertaking that we've been on.
