Satsearch blog is the company blog at blog.satsearch.co, writing about hardware and business. Since 2018, 4 different Hacker News readers have linked it 97 times, most often “A guide to selecting the right star tracker for a satellite”. It is still writing: the last post was on 2026-10-22, and you can follow it by feed.
Too few sampled comments (1) to say how often HN recommends it.?
Why HN links it
The linked post is about computational photography, from selfies to black holes, per its HN thread title. The one comment discusses celestial navigation by star tracking as a GPS alternative and does not assess the post.
Summarised by Claude from a sample of 1 HN comments that link here. Each comment is marked recommending, critical or neutral (citing without judging); how this works.
In-depth resources for space engineers and industry professionals, along with news & updates from our work building the global marketplace for space.

What Hacker News says?
There's actually strong synergy. There's a lot of spin-in and spin-out going on between space and non-space sectors. COTS and general commodization of "discete units" (parts, subsystems, assemblies, etc.) is one of the biggest drivers for the commercialization of space. It's enabling people to move towards the use of advanced manufacturing techniques, cutting lead time and cost, and enabling batch production. We rec…

HN discussionThe satellite ground station market is quite dynamic at the moment. As the data generated on-orbit continues to grow, the need for robust ground infrastructure becomes that much more important. Ground-Station-as-a-Service (GSaaS) is something that AWS stepped into given the fact that AWS is used quite extensively for the data processing chain, so it was a logical play for them to verticalize. AWS partnered with Lock…

HN discussionOn the extreme end, if you live in the countryside you can replace GPS entirely using celestial navigation/star tracking. This is commonly used for rockets and satellites but right now if you own a truck or pickup you can easily go completely off-grid by mounting a lens on the rooftop. E.g. http://nova.astrometry.net/ For implementing the system on an embedded device e.g. toy drone, raspberry pi etc., the main data…

HN discussionI have "datasheet-envy". I'm one of the co-founders at satsearch [1], where we're working on fixing procurement in the space industry. We're constantly battling shitty datasheets. As a space engineer, I found it infinitely frustrating to work with flyers that suppliers provide on their website, that also double-up as preliminary datasheets. They're messy, inconsistent, and subject to whatever the supplier thinks the…

HN discussionSpace tugs have been a topic of research for quite a while in the space community. A number of companies targeting the in-space space transport market over the last few years, e.g., [1][2]. There's also a recent YC alum targeting this [3]. Propulsion is itself a really hot topic in the NewSpace market the moment, ranging from tiny thrusters for precision attitude control of smallsats, to large systems for orbital tr…

HN discussionEric Berger has a lot of really great stories about what's going on in the space industry. Smallsats have been the story of the sector for going on two decades now. I've got a background in both space engineering and planetary science. One of the most exciting things that I see happening over the coming decade is commoditization of planetary probes. There's so much more of the Solar System that we still have to expl…

HN discussionHey folks, nice to see this article hit the frontpage. I'm one of the co-founders at satsearch. We're working on building more content like this to open up the space industry to more people. After some initial feedback, we're already working to expanding this article. We've also published articles on small satellite thrusters [1] and reaction wheels [2]. We'll be publishing one on ground-station-as-a-service soon. W…
