Bridgit Mendler joins TBPN to discuss Northwood Space's mission to modernize ground network infrastructure through a scalable, software-defined network of ground stations. Following a $30 million funding round, Mendler explains how Northwood solves critical space data bottlenecks to support real-time Earth observation, multi-orbit satellite operations, and national security resilience.

speaking balance: gold is the hosts, purple is the guest (3 minute bins)
Sharpest disagreement ▶ 21:00 Polite reframing of government interest urgency
In a very friendly interview, Mendler's firmest correction is clarifying that government involvement is immediate and critical, not a distant future consideration.
Hardest push from the hosts ▶ 12:04 Probing value chain and manufacturing economicsCoogan presses Mendler on whether Northwood is actually manufacturing hardware or merely assembling off-the-shelf components.
Biggest teaching moment ▶ 4:48 Explaining RF physics and modern routing shiftsMendler provides a comprehensive breakdown of RF concentration and contrasts antiquated telescope scheduling with internet-style routing.
The host holds their own ▶ 8:49 Coogan cites commercial space players and orbital regimesCoogan demonstrates industry fluency by referencing Albedo, Astronis, and Impulse Space across VLEO and orbital transfer mechanics.
the scores for every segment, with the reasoning behind each
| Chapter | Topic | The hosts as informed peer | Guest teaching | Guest disagreement | The hosts pushing back | Why |
|---|---|---|---|---|---|---|
| Scaling Ground Station Networks for Global Coverage and Capacity | 3 | 6 | 0 | 0 | The hosts ask foundational questions about network scaling and the history of ground communications, framing it in simple terms. Mendler educates them on the physics of RF power concentration, parabolic dishes like the Stanford dish, and shifting from bespoke telescope booking to automated software-defined routing. | |
| Enabling Real-Time Earth Observation and Disaster Response | 3 | 5 | 0 | 0 | Hays asks about new business models enabled by low-cost ground stations, and Mendler details how low-latency downlink transforms disaster response like tracking rapid wildfires. | |
| Multi-Orbit Communications Across VLEO, LEO, MEO, and GEO | 4 | 5 | 0 | 0 | Coogan shows domain awareness by referencing orbital startups like Albedo, Astronis, and Impulse Space. Mendler explains the trade-offs between VLEO, LEO, MEO, and GEO ground requirements and highlights the shortage of assets in higher orbits. | |
| The Origin Story Behind the Name 'Northwood' | 3 | 3 | 0 | 0 | Coogan asks a lighthearted naming question followed by a serious inquiry on supply chain integration and manufacturing. Mendler outlines their strategy of outsourcing modular subsystems before gradually bringing core capabilities in-house. | |
| Site Selection Criteria and Modular Ground Station Deployment | 4 | 4 | 0 | 0 | Coogan asks about land rights, siting logistics, and compares it to Anduril's mobile sensor towers. Mendler breaks down the core site selection triad of land, fiber, and power along with avoiding concrete foundations. | |
| Decoupling Ground Infrastructure Operations from Launch Timelines | 2 | 2 | 0 | 0 | The conversation shifts to speculative topics like space tourism and p-Moon probabilities. Mendler explains the operational upside of being decoupled from launch provider schedules. | |
| Dynamic Beam Tracking and Spaceflight Communications | 3 | 5 | 0 | 0 | Coogan raises video signal dropouts during Blue Origin suborbital flights. Mendler uses the flashlight beam analogy to explain how varying beam width is necessary to track dynamic, non-standard spaceflight trajectories. | |
| Commercial Dual-Use Infrastructure for Government Resilience | 4 | 4 | 0 | 0 | Coogan asks about dual-use defense applications and industry decomposition into satellite buses and payload downlinks. Mendler explains how defense interest in commercial ground stations stems from the vulnerability and age of legacy military infrastructure. | |
| The Founding Story and White Papers of Northwood Space | 2 | 2 | 0 | 0 | The interview wraps up with casual founding origin stories involving quarantine prototyping and drafting white papers, ending in cordial banter over energy drinks. |
Statements from this episode (14)
Mendler: Northwood is building a shared ground network for the space economy
“We're building the ground network for the industrialized space economy. You know, we view it kind of as the third critical pillar of infrastructure for space where you need to get things into space on rockets. You need to have things to put into space, which a…”
Mendler: Northwood Space aims to build 500 ground station sites near-term
“So our kind of you know, sub near term goal is 500 sites.”
Mendler: Individually booking ground antennas cannot scale with the space industry
“As the space industry has been scaling it's not really a sustainable model to think of, like, as you're needing to coordinate, you know, tens or hundreds of different sites to think about that individual booking and coordination”
Mendler: Space communication will transition to software-defined global networks
“How the space industry is going to evolve in terms of communication, going from booking an antenna, like you book a science telescope to, Having the outcomes through a global network where you can you can have a lot of observability and control into that netwo…”
Mendler: Satellite wildfire tracking is useless without low-latency downlinks
“The challenge with that is if you don't have your latency down low enough to be able to give the information, it's pretty much useless, right? Like if you deliver information like an hour later, then you can't you can't deliver anything actionable and helpful …”
Mendler: Higher orbit ground station shortfall is a major Northwood driver
“Like there's really a shortfall of ground assets in the higher orbits actually. And so that's something that we didn't enter into the business planning on, but that's something that has been like a very large driver of activity in our business over the past, l…”
Mendler: Northwood designs all components in-house while outsourcing early manufacturing
“We are a vertically integrated company. Like we design all of the different components. We have those outsourced and then you know, brought in. We're not you know, like making our own circuit boards at this point in time.”
Mendler: Data centers are ideal satellite ground stations due to existing infrastructure
“So data centers honestly become like a good spot to put them at because they have the power in the backhaul already set up.”
Mendler: Northwood avoids concrete pads to eliminate ground station permitting delays
“One advantage of the way that we're building our systems is we don't need to lay like a concrete pad, which can add Weeks to months to your timeframe, especially when you need to like do permitting and all that.”
Mendler: Ground infrastructure lets Northwood operate free from launch schedule constraints
“It's very convenient. We can work on our own schedule. I mean, we have different challenges cause you know, you're going to different countries and they have their own local regulatory regimes and all that, but we are not constrained by launch schedules, which…”
Mendler: Northwood is developing tech to track changing beam widths dynamically
“And we're excited through you know, the tech that we're developing to be able to track the beam with us. As it changes for more dynamic trajectories.”
Mendler: Government and defense contracts are a near-term focus for Northwood
“No, it's very near term. It's very real term. Very real term. Very, very real. Yeah. Across a number of different applications.”
Mendler: Legacy government ground networks are sparse and vulnerable to outages
“They have aging assets that are kind of infrequent. Like there's, you know, certain networks that just don't have a lot of assets and they're old and they're vulnerable to outages, whether it's like an intentional outage. You know, by somebody targeting that s…”
