航天任务的核心:地面连接
Bridget: 每一颗卫星都需要一个连接回地球的切入点。如果没有这个连接点,你就不算拥有一个航天任务。从字面上看,它就像是一块漂浮在太空中的石头。
Original English
Bridget: Every satellite requires a connection point back to Earth. If you don't have it, you don't have a space mission. It literally is just like a rock in space.
主持人: 你们刚刚获得了**美国太空军(Space Force)**一份价值 5000 万美元的合同,旨在帮助其实现现代化。
Original English
Host: You just want a $50 million contract with Space Force to help modernize.
Bridget: 在 Northwood,我们希望让航天任务走得更远、更快。我们追求的是**范式级(categorical)**的结果,而不只是微小的增量。
Original English
Bridget: At Northwood, we want to take space missions further faster. We're looking for a categorical outcome, not just an incremental outcome.
主持人: Starlink 正在研发直接的光学星间链路。这在多大程度上构成了威胁?
Original English
Host: Starlink is working on direct optical inner satellite links. How much of that is a threat?
Bridget: 我认为威胁几乎为零。SpaceX 能够将发射成本降低一个数量级。但为什么地面端的成本和效率没有发生同样的变革呢?
Original English
Bridget: I view it as like a 0% threat. SpaceX was able to bring launch cost down by an order of magnitude what came before. Why hasn't the same thing happened at ground?
跨界路径:从演艺到航天
主持人: Bridget,欢迎来到播客。我们今天聊聊 Northwood,聊聊太空。但首先我想谈谈你是如何走到这一步的。有些人可能会说,这是一条非典型的职业道路。回顾你的职业生涯曲线,是什么线索将这些点串联在一起的?你如何解读自己的路径?
Original English
Host: Bridget, welcome to the podcast. So we're here to talk about Northwood. We're here to talk about space. But first want to talk about how you got here. Uh, when, uh, you know unconventional career paths some may say, when you look at the arc of your career what are the threads that tie it together how do you make sense of your path?
Bridget: 我想是追随好奇心。好奇心对人们来说是最有机的动力,对我来说也是如此。我的家庭环境从小就在培养这种好奇心,我的父母也一直鼓励追求卓越。如果你对某件事好奇,就不只是涉猎,而是要把它做到极致(nth degree),真正理解那个领域的“卓越”是什么样子的。这带我去了很多不同的地方。我母亲是一个意志力极其坚定的人,这对我影响很大:追随好奇心,竭尽全力去做,不要接受否定。这样你最终会尝试很多不同的事情,获得非常有意思的经历。
Original English
Bridget: You know, following curiosity, I think curiosity becomes the most organic motivator for people and that's definitely the case for me. I think you know my my home environment growing up was really uh cultivating that curiosity and my parents also really encouraged excellence which I think is great so you know if you're curious about something, it's not just something you dabble in. It's something you try to take to like the nth degree and and really like try to understand what excellence looks like in that domain. And so that kind of is, you know, led me to a lot of different places. My mom is also an incredibly determined person. And so that's something that I think I was influenced by. And so like, you know, follow what you're curious about, do it to the greatest capacity you can and don't take no for an answer and then you kind of wind up like doing a bunch of different things in some really interesting experiences.
主持人: 这很有趣,因为人们有时会把这二者对立起来:要么是给孩子压力要求拿全 A+,要么是随他们好奇心发展。但你的组合是:做你好奇的事,并在这个领域彻底击败对手。这种结合很有意思。在职业生涯早期,你是否想过某件事会是一辈子的事业,还是在某个时刻会觉得“我厌倦了,我想去学术界”?你是如何做职业决策的?
Original English
Host: It's fascinating because sometimes people frame it as either or, either like you got to get you know just especially for kids like just straight A pluses uh or it's you know just do whatever you're curious about but the combination like do what you're curious about but also just absolutely crush it in it. It's a interesting combination. Yeah. sort of in your early career, did you think it would be forever or like at one point were you like, I'm bored of this. I want to go into academia like how did how did you make your career decisions?
Bridget: 有趣的是,我可以以此类比我们公司招聘的那些顶尖人才。这些职场中的“摇滚明星”通常不会去思考未来 20 年的职业规划。他们思考得更具增量性,也许没有明确的时间表,但会尽力望向地平线的尽头,只担心目前能看得到的范围,否则你会给自己太多的约束。我对待职业生涯也是如此,我绝对没预料到自己会运营一家航天公司。
Original English
Bridget: You know, it's interesting because like I I would analogize to how a lot of people that we bring into our company think about their career path. Like a lot of the incredible people that we bring in, people who are like totally rock stars in their career, they're not thinking on like a 20-year time scale about their career. they're thinking more incrementally than that. am, you know, maybe there's not a definite timeline attached to it. It's like as far out as you can see on the horizon and just like worrying about that far cuz otherwise you constrain yourself too much. Um, and so that has really been how I've approached my career. I I would have definitely not expected I would be running a space company.
主持人: 所以你曾是一个演员,直到它不再有趣,或者直到学术界变得更有吸引力,然后你一直在追随好奇心。那么,创业的想法是什么时候出现的?
Original English
Host: So you were like actress until it no longer became fun anymore or until academia or something became more interesting and then in academia you were like or at some point you were like and then you were just chasing your curiosity and then you're like, oh maybe when did the company idea come into play?
Bridget: 在娱乐圈时,我曾为很多不同的事情担任代言人,我试图将自己认为有影响力的事情与我的发言联系起来。演员拥有一个平台可以为各种事业做贡献,但我希望我的影响力能更深入。我潜意识里一直想创造属于自己的东西。作为千禧一代的孩子,我目睹了互联网的诞生和蜂窝网络的兴起,以及它们给世界带来的深刻转变。当**太空网络(Space Networking)**的问题出现并开始深入挖掘时,它在更深层次上触动了我:这是一个有机会对某个行业产生根本性影响的机会,就像互联网和蜂窝网络那个级别。这种在行业早期阶段切入的独特性,看起来就像是一件完美的事情。
Original English
Bridget: Yeah I think being in entertainment I got to be a spokesperson for a lot of different things and I and I tried to align what I felt to be impactful with what I was speaking up for. So you know as an actor you wind up being able to have a platform to contribute to a lot of different causes and that was something that I prioritized but I think I wanted my impact to go deeper than that. And so I I always kind of knew in the back of my mind I wanted to create my own thing although you know I didn't have like a concrete idea of what that was and as a child of you know millennial era I got to see the internet coming to life and I got to see cellular networks coming to life and like what a profound shift that was on um the world before versus the world after. And so I think uh when the problem set around space networking came up and when that was something that I started digging into it connected on that deeper level where it's like wow this is um something like an opportunity to make an impact on an industry that could be as fundamental at that kind of level of of internet and cellular that felt like such a unique opportunity to get in at an industry when it was at that early stages.
北木空间(Northwood Space)的诞生
主持人: 你是和丈夫一起创业的。他从一开始就支持吗?这是如何形成的?顺便说一下,我的父母也曾共同经营一家公司 15 年,这确实受我母亲的影响。
Original English
Host: And you started it with your husband. Was he always uh on board from the beginning or how did that emerge? And I should say my parents also started a a company together and ran it for 15 years. Definitely inspired by the mom.
Bridget: 太酷了。人们现在常说“哦,你和丈夫一起创业”,但其实家族企业自古就有。我们两个都非常有野心,对世界的运作方式充满好奇,也对建立商业充满热情。所以当时的想法是:让我们把力量整合在一起。这其中有一定的功利主义考量——我们的精力和时间是有限的,我们希望产出最大的净收益。
Original English
Bridget: That's super cool. Yeah. I mean, it's so funny how people are now like, "Oh, you start a company with your husband." But like people have been doing family businesses like since the dawn of time. Um Yeah. And and I think for both of us, we're just both ambitious. um and kind of curious about how the world works and we we were both passionate about you know building businesses and so it was like all right let's align our efforts towards something like there's a certain utilitarian aspect to it where it's like we have a certain amount of energy and time and we want the most like net outcome from this.
主持人: 让我们深入聊聊 Northwood。你们试图实现什么?为什么是现在?
Original English
Host: talk about let's get into Northwood um what you're trying to achieve um and and what's the why now for it?
Bridget: 我们为航天公司提供端到端的地面基础设施。从他们最初构思卫星任务,到太空运营商想要做什么,一直到实际流式传输数据并交付给终端客户。我们解决的问题是:每一颗卫星都需要一个连接回地球的切入点,以便控制航天器。它有点像一辆遥控赛车,需要某种机制确保它按照预定轨道行驶,并将数据带回地球上的用户。这个地球上的接触点就叫地面基础设施。基本而言,如果没有它,航天任务就无法存在。没有地面设施,卫星就只是太空中的一块石头。
我们观察到,航天工业的发射频率正在增加,卫星的建造和发射速度越来越快,因为整个航天器制造领域正在兴起。但有趣的是,整个链条中最慢的一环(longest pole in the tent)变成了地面连接点。你能比地面连接点更快地造好并射出一颗卫星,这看起来很荒谬。为什么地面端没有现代化?当我们深挖时,发现这是一个典型的价值链问题:价值链上的每个利益相关者都没有现代化的动力。天线制造商只负责交付单一的硬件方案,他们不从整体角度思考如何构建更好的地面基础设施。软件集成层则依赖于别人的基础设施。只有通过涵盖整个流程(垂直整合),才能真正解决地面段的问题。
这包括天线硬件的研发、土地征用(因为卫星绕地球运行,你需要在世界各地布置天线)、网络层以及连接地面站发出指令的 API 软件。这是一项艰巨的任务,一个巨大的风险,但背后是巨大的回报:解锁航天经济的关键第三大支柱。
Original English
Bridget: 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, you know, 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. Yeah. You know, the problem that we're solving is for every satellite, it requires a connection point back to Earth so that they can uh control the spacecraft. You know, 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. Um, so that point of contact on Earth is called the ground infrastructure and you know super basically if you don't have it you don't have a space mission. It literally is just like a a rock in space you're doing nothing with. So ground in infrastructure it's it's completely fundamental. Um and for us uh you know we we were observing the space industry how launch cadence was increasing. you could you could put a satellite up into space way faster and you could build satellites way faster because there was this whole um boom around spacecraft manufacturing 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, you know, 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 to modernize and innovate. So you had, you know, antenna manufacturers that were, you know, responding to a call from a customer and delivering them uh a point solution. They weren't thinking like holistically about how you you build better uh ground infrastructure. You were having like a a 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 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.
从“地面极客”到垂直整合
主持人: 你们是什么时候以及如何意识到航天基础设施出问题的?是在哪个“想法迷宫”里探索出来的?这是你们第一个决定追求的想法吗?
Original English
Host: And when did you realize and how did you realize that space infrastructure was broken? like what was the idea maze that you guys went? Was this your first idea um that you guys decided to pursue or Yeah. How did they come to be?
Bridget: 伙计,自从大流行期间那次去 Home Depot 采购后,我们就一直在折腾天线。那让我们变成了“地面极客”(ground nerds)。我们在大流行期间开始研究天线设计,那是我们的夏季项目。起初只是觉得能接收到数百英里外的信号太酷了。射频(RF)波比太空发出的手电筒光还要微弱,而你需要把它解读成图像,或者对其他人来说是导弹预警信号、GPS 信号或唯一的互联网来源。那是一个神奇的时刻,你会对这项技术产生深深的着迷。接着我们做了市场调研,看了所有的商业运营商和美国政府的使用案例,意识到一个巨大的瓶颈即将来临。
Original English
Bridget: Yeah, man. We've been doing antennas ever since that that Home Depot run during the pandemic. Yeah. Uh that made us ground nerds. Um yeah, so we were uh we started working on the antenna uh designs during the pandemic. Uh, you know, that was our our summer project and yeah, we just describe ourselves as ground nerds. It was just cool. At first, it was just really cool to be able to receive signals from hundreds of miles away. Like I said, that's the RF waves. They're like fainter than um, you know, the power on a flashlight that you're getting from space. and you get to interpret that into, you know, for us it was an image, but for other other folks that use satellite data. That's, you know, that's our missile warning system. That's how we find out like about any missile going off around the world. That is our GPS infrastructure. That is our uh, you know, for a lot of people that's their one source of internet and it all all comes through a ground infrastructure that is able to interpret those faint signals and make it work. So it was just kind of like you know one of those magic moments where you just become really fascinated with the technology and then we started peeling it back further and we uh we did this market study where we looked at all the commercial operators. Um we looked at you know US government use cases as well for how that they were resolving their ground and it was at that point really from the point of first just being curious about the space that we realized that a big bottleneck was coming.
主持人: 这个想法在五年前是否无法存在?因为当时还没有足够的航天经济规模?聊聊时机问题。
Original English
Host: Yeah. And is this an idea that couldn't have existed five years ago because there was just not enough of an economy around or um in like Yeah, talk about the timing of it.
Bridget: 时机确实很关键。以前,如果你不介意从概念到发射之间有三年的间隔,那么地面段跟不上节奏也不是大问题。但现在航天任务的理念发生了巨大变化。我们现在讨论的任务规模大得多,涉及更多的航天器同时通信。卫星的运行方式也变得非常动态,在不同的轨道间进出。以前的航天任务比较静态,像是科学任务,一颗卫星停在固定位置发回少量数据。而现在是一场“马戏团”,各种任务共存,传输更多数据,参数不断变化。无论是政府还是商业客户,没有新的地面架构,他们的任务就无法完成。
Original English
Bridget: Yeah, I I think um it really does influence the timing because previously if you're not as easy concerned about a three-year timeline between, you know, concept of a spacecraft and and launching it, then um it's not a big deal if the ground segment can't keep pace. I also think like the ideas for how to use space have changed a lot both so you know pace as well as the the ideas around it. So the mission sets that we're talking to folks about now um are a greater level of proliferation. They're talking about way more spacecraft being in communication at the same time than they used to. They're talking about mission sets where satellites are moving in new ways. They're moving really dynamically uh in and out of different orbits. Um, you know, previously you could think about uh space missions. It was a pretty static world. Like think about old school space where it's it's kind of like science missions, one satellite parked over a certain location, not moving anywhere, sending very small amounts of data to now it's this whole circus of uh a bunch of different missions needing to coexist, transmitting way more data and uh having like constantly changing parameters.
垂直整合:从三年到三个月
主持人: 你们的系统能在 3 个月内部署,而传统的地面站需要 3 年。是什么让你们实现了这种速度的提升?
Original English
Host: Yeah your system is able to deploy in 3 months whereas a traditional ground station deploys in three years. What enables you guys to have that level of speed up?
Bridget: 归根结底是垂直整合。这意味着我们将端到端系统中的所有不同环节缝合在一起。以前 3 年的周期是怎么样的?天线供应商接到电话,向供应链下单,等几个月零件到货,然后组装。这通常是定制的(bespoke)生产线。发货时需要海运。到达现场后,需要进行巨大的建设工程,因为很多天线像多层楼房那么大。你需要许可证、打混凝土基础、施工团队。这一切加起来就是 3 年。
而对于我们,因为我们在研发时同时考虑所有这些事情,我们要求天线必须能装进标准集装箱,可以用美联航的商业航班空运,当天就能到达。我们的系统可以直接从集装箱里卸下,落在泥土地上,不需要混凝土,直接插入标准的 240V 电源。我们的遥测系统贯穿整个架构,几分钟内就能启动。这种协调能力最终缩短了时间。
Original English
Bridget: It really comes down to the vertical integration. And what we mean by that is kind of like what I what I mentioned of being able to stitch together all of the different pieces in the endto-end system so that they inform each other. So for example, when we say 3 years before, what did that timeline look like? It looked like an antenna vendor who, you know, gets a phone call. After they get the phone call, they press the order on the supply chain. they got to wait x number of months to actually get the parts to arrive. Then they assemble them all. It's a bespoke manufacturing line because it's, you know, it's a bespoke system. They're just, you know, they're doing it uh one off and then they ship it and they're shipping a giant piece of equipment. So, it probably has to go over, you know, uh, ocean, uh, shipping methods. And then it arrives at site and you have to put together a giant construction project because the size of many of these antennas, they're like multi-story buildings. So, you have to do permitting, you have to lay a concrete foundation, you have to have whole construction teams in order to put them together. That adds up into a three-year timeline. Whereas for us, because we're thinking of all of those things at the same time as we're doing that development, we get to say we need our antennas to fit in a standard shipping container that can go on a commercial United Airlines flight and so it gets there the same day. We need our system to be able to fork off of that shipping container and land on a patch of dirt with no concrete and and just plug into a standard 240 power bolt. Um, we need to be able to have that telemetry run across our entire system so that we know how to fire it up in a matter of minutes.
对标 SpaceX:共享基础设施平台
主持人: SpaceX 能够将发射成本降低一个数量级。为什么地面端没有发生同样的情况?
Original English
Host: SpaceX was able to bring launch cost down by an order of magnitude from what came before. Why hasn't the same thing happened in ground?
Bridget: 还是垂直整合。SpaceX 极大地简化了他们的产品。他们不尝试建造一堆定制产品,而是制造一种东西,并让它变得极其高效和有效,从而获得规模经济。如果我们只是天线供应商,我们就得建造各种不同类型的产品。但因为我们能够看到各种解决方案,我们可以投资研发一种在全行业通用的方案。这意味着我们将商业任务、政府任务和盟友任务全部纳入同一个系统,这降低了成本并提高了效率。
我们将自己视为一个平台(platform),而不是一比一的销售。我们的平台让许多任务受益于相同的基础设施。我们进行一次投资,众多客户都能从中获益。客户不需要一次性支付巨大的资本支出(CAPEX),他们可以分摊成本,每个人都很满意。
Original English
Bridget: Yeah. I think it it does come down like I hate to be a broken record on the vertical integration, but um the reason why that matters is that uh what SpaceX has done is they've really streamlined their product, right? Like they're not trying to build a ton of different bespoke products. They build one thing and they make it super efficient and effective. They get the economies of scale and everything. And so for us, if we were, you know, just being an antenna vendor, then we would probably need to build a bunch of different types of products. But because we get to um see across so many different solutions, we can think and we invest our R&D in building a solution that works commonly across the industry. So that means that uh you know we're accounting for commercial missions, government missions, allied missions all within the same system. Uh and that makes our costs lower and more efficient. Um and when we're able to do it as a shared service, uh that's really the difference for us. Like we we view ourselves more so as a platform, right? So it's it's not like a onetoone sale where you're trying, you know, get all of your uh value off of that single sale. Our platform is such that many missions can benefit from the same infrastructure. So we make our investment and then many customers get to benefit off of that single investment that we make.
太空互联网的“TCP/IP”时刻
主持人: 很多人将太空经济类比为早期互联网。这种类比对你适用吗?
Original English
Host: A lot of people analogize the space economy to the early internet. they say you know a lot of infrastructure being built you know lots of companies will fail uh and lots of applications you very successful applications will be built on top do you does this analogy hold for you?
Bridget: 当然适用。尤其是想到早期互联网的人们根本无法预见今天的样子,但他们押注了一个方向,并建立了一个能解锁大量创新的模型。他们制定了原则,并根据原则进行构建。就像 TCP/IP 协议,尽量让不同层级变得简单并支持创新。
在航天工业,我们正处于类似的时刻。我们不知道未来会造出什么。一年前,会有人讨论轨道数据中心吗?绝不可能。但它现在吸引了公众的想象力。我们追求的是那些最具雄心的愿景,并将其从梦想变为现实。我们想成为航天工业中那种基础性的、具有影响力的平台基础设施公司,就像云服务之于互联网。
Original English
Bridget: yeah for sure um I get really inspired by the analogy um especially thinking about you know for folks that were early with the internet like they there's no way they would have foreseen what the internet is today um but they were betting on a direction and they were setting up a model that would uh that would basically like unlock a lot of innovation and they they were like uh they were developing principles and building aligned with certain principles that would support that innovation and and look what we have today. Um yeah I mean I think like things as simple as like TCP IP protocols for example like trying to make different layers as as easy and supporting for innovation as possible. So, I think we're in a similar moment with the space industry where we don't know what is going to be built. Like a year ago today, would we think that everybody would be talking about orbital data centers? No way. Um, but it's captivated the public imagination and who knows what's going to come next.
企业文化:挑战不合理的任务
主持人: 聊聊 Northwood 的文化,以及你们想吸引什么样的人。
Original English
Host: Cool. Talk a little bit about how you think about culture at Northwood. you know, what types of people you're you're trying to bring on, how you think about demolding.
Bridget: 我在面试时会分享三点期望。第一,我们要在不合理的时间表内完成不合理的事情(unreasonable things)。这不只是靠蛮力,还要靠聪明才智,深入理解问题,知道哪些权衡是可以接受的。第二,端到端的责任感(end-to-end ownership)。我希望人们不仅仅是勾选任务清单,而是对结果有深度的投入。
这源于我的母亲。她是一个全职工作的母亲,曾是家里唯一的经济支柱。当我小时候想当演员时,很多父母可能会把我送进演艺营就撒手不管了,但我母亲在电话里协调旅行、找看护人、订机票,想尽办法为我实现梦想。这种超越常理的投入感一直激励着我。在我们的北达科他州部署任务中,团队成员为了让系统运行,一周内多次连续工作超过 24 小时。
第三,我们追求的是范式级的结果(categorical outcome)。如果你想推动世界前进,你需要一个充满信任的团队。而信任的关键在于低自尊(low ego)的环境。人们需要能够承认自己的错误,纯粹地追求对问题的理解,并有勇气在出现问题时发出预警。
Original English
Bridget: I'll give a little window into my uh expectations that I share with people when um they interview for Northwood. The first one is that we accomplish unreasonable things on unreasonable timelines. They surface level like sure, okay, everybody, you know, everybody can kind of get on board with that. But, uh, you know, it's not just a matter of like applying more force to the problem. Um, it's about taking smart risks. So, it's not just force, it's also cleverness. It's like understanding the problem deep enough to know what the trades are that you can afford to make. Um, and so people that are able to do that kind of uh mental calculation and kind of like take take big leaps is really how you can actually move quickly. Um, the the second one is the endto-end ownership of your work. And for me really what that translates to is, you know, people who are going to be bought in in a deeper way to the outcome beyond just checking some boxes off the list. And then the third one is um uh we're looking for a categorical outcome not not just an incremental outcome.
主持人: 这是一个很好的总结。关于你母亲的故事非常感人。谢谢分享,Bridget,谢谢来到播客。
Bridget: 谢谢邀请。
