SpaceX seeks patent for custom-built Starlink internet satellite antenna design
Update: Readers on Reddit more familiar with patent processes have noted that the USPO filings written about herein were not patent grants but rather patent applications. While a patent grant is not guaranteed and will likely take many additional months to be completed, all other points made in this article still stand.
SpaceX has been granted domestic (U.S.) and international patents for a custom version of an antenna known as a phased array, in this case featuring significant upgrades in pursuit of greater energy efficiency, higher bandwidth, lower weight, and simplified manufacturing, all things that would be a boon for the realization of SpaceX’s global Starlink internet satellite constellation.
With a minimum of ~4400 satellites required for the first wave of global and continuous internet coverage, SpaceX will need to invent unprecedented methods of mass-producing efficient and reliable spacecraft on a scale that has never been attempted in the satellite manufacturing industry.

While highly technical and difficult to parse, the granted patent and the dozen or so figures accompanying it offer at least a theoretical glimpse into the inner workings of SpaceX’s extremely secretive satellite internet constellation project, the hubs of which can be found in Seattle and Redmond, Washington. Currently employing at least 300 people dedicated to Starlink, the teams involved are pushing full speed ahead into a new phase of manufacturing design and development, evidenced in part by hiring patterns and even this patent, which itself places significant focus on manufacturability, a telltale sign that SpaceX is unlikely to let it sit around gathering intellectual property dust.
It’s entirely possible that SpaceX has chosen to file patents through individual employees or shell LLCs, but this phased array antenna patent – filed in February and granted in August 2018 – is by all appearances the third patent ever granted directly to SpaceX, alongside aluminum-honeycomb manufacturing and a critical component of its Merlin rocket engines. Perhaps this serves as some sort of indicator of how important Starlink actually is behind the veil, although it may also simply reflect the intense competition circling the prospects of a low Earth orbit satellite internet constellation.

Other companies like OneWeb and Telesat are also racing to field their own several-hundred or several-thousand satellite constellations, and OneWeb may well be the closest to actually serving customers with operational satellite launches potentially beginning as early as December 2018 to February 2019. Still, SpaceX’s own prospective Starlink constellation is exceptional due to the sheer amount of work that the company is attempting to do in-house, to the extent that senior leaders of the R&D team have recently implied that work not done in-house was generally outsourced only due to “lack of engineering bandwidth”.
Ultimately, this patent and many of the diagrams within suggest that SpaceX may actually be getting relatively close to mass-production of high-performance Starlink satellites. Of particular note, the integrated circuit CAD view offered in Figure 6A hints that an impressive amount of work has been put into designing, building, testing, and refining custom and application-optimized computational hardware, an entirely new and highly complex field for SpaceX to enter into.

GM CEO Mary Barra says she told Biden to give Tesla and Musk EV credit
“He was crediting me, and I said, ‘Actually, I think a lot of that credit goes to Elon and Tesla…You know me, Andrew. I don’t want to take credit for things.”
General Motors CEO Mary Barra said in a new interview on Wednesday that she told President Joe Biden to credit Tesla and its CEO, Elon Musk, for the widespread electric vehicle transition.
She said she told Biden this after the former President credited her and GM for leading EV efforts in the United States.
During an interview at the New York Times Dealbook Summit with Andrew Ross Sorkin, Barra said she told Biden that crediting her was essentially a mistake, and that Musk and Tesla should have been explicitly mentioned (via Business Insider):
“He was crediting me, and I said, ‘Actually, I think a lot of that credit goes to Elon and Tesla…You know me, Andrew. I don’t want to take credit for things.”
GM CEO Mary Barra said to Andrew Sorkin at the New York Times Dealbook Summit that she pulled President Biden aside and said Tesla CEO @elonmusk deserved the credit for EVs:

Back in 2021, President Biden visited GM’s “Factory Zero” plant in Detroit, which was the centerpiece of the company’s massive transition to EVs. The former President went on to discuss the EV industry, and claimed that GM and Barra were the true leaders who caused the change:
“In the auto industry, Detroit is leading the world in electric vehicles. You know how critical it is? Mary, I remember talking to you way back in January about the need for America to lead in electric vehicles. I can remember your dramatic announcement that by 2035, GM would be 100% electric. You changed the whole story, Mary. You did, Mary. You electrified the entire automotive industry. I’m serious. You led, and it matters.”
People were baffled by the President’s decision to highlight GM and Barra, and not Tesla and Musk, who truly started the transition to EVs. GM, Ford, and many other companies only followed in the footsteps of Tesla after it started to take market share from them.

Musk would eventually go on to talk about Biden’s words later on:
“They have so much power over the White House that they can exclude Tesla from an EV Summit. And, in case the first thing, in case that wasn’t enough, then you have President Biden with Mary Barra at a subsequent event, congratulating Mary for having led the EV revolution.”
In Q4 2021, which was shortly after Biden’s comments, Tesla delivered 300,000 EVs. GM delivered just 26.

Tesla Full Self-Driving shows confident navigation in heavy snow
So far, from what we’ve seen, snow has not been a huge issue for the most recent Full Self-Driving release. It seems to be acting confidently and handling even snow-covered roads with relative ease.
Tesla Full Self-Driving is getting its first taste of Winter weather for late 2025, as snow is starting to fall all across the United States.
The suite has been vastly improved after Tesla released v14 to many owners with capable hardware, and driving performance, along with overall behavior, has really been something to admire. This is by far the best version of FSD Tesla has ever released, and although there are a handful of regressions with each subsequent release, they are usually cleared up within a week or two.
Tesla is releasing a modified version of FSD v14 for Hardware 3 owners: here’s when
However, adverse weather conditions are something that Tesla will have to confront, as heavy rain, snow, and other interesting situations are bound to occur. In order for the vehicles to be fully autonomous, they will have to go through these scenarios safely and accurately.
One big issue I’ve had, especially in heavy rain, is that the camera vision might be obstructed, which will display messages that certain features’ performance might be degraded.

I found the steepest, unplowed hill in my area and tested the following:
• FSD 14.2.1 on summer tires
• FSD 14.2.1 on winter tires
• Manual drivingBut I think the most impressive part was how FSD went DOWN the hill. FSD in the snow is sublime $TSLA pic.twitter.com/YMcN7Br3PU

Well.. I couldn’t let the boys have all the fun!
Threw the GoPro up and decided to FSD v14.2.1 in the snow. Roads were not compacted like the other day, a little slippery, but overall doable at lower speeds. Enjoy the video and holiday music 🎶

Moving into the winter months, it will be very interesting to see how FSD handles even more concerning conditions, especially with black ice, freezing rain and snow mix, and other things that happen during colder conditions.
We are excited to test it ourselves, but I am waiting for heavy snowfall to make it to Pennsylvania so I can truly push it to the limit.

Tesla hosts Rome Mayor for first Italian FSD Supervised road demo
The event marked the first time an Italian mayor tested the advanced driver-assistance system in person in Rome’s urban streets.
Tesla definitely seems to be actively engaging European officials on FSD’s capabilities, with the company hosting Rome Mayor Roberto Gualtieri and Mobility Assessor Eugenio Patanè for a hands-on road demonstration.
The event marked the first time an Italian mayor tested the advanced driver-assistance system in person in Rome’s urban streets. This comes amid Tesla’s push for FSD’s EU regulatory approvals in the coming year.
Rome officials experience FSD Supervised
Tesla conducted the demo using a Model 3 equipped with Full Self-Driving (Supervised), tackling typical Roman traffic including complex intersections, roundabouts, pedestrian crossings and mixed users like cars, bikes and scooters.
The system showcased AI-based assisted driving, prioritizing safety while maintaining flow. FSD also handled overtakes and lane decisions, though with constant driver supervision.
Investor Andrea Stroppa detailed the event on X, noting the system’s potential to reduce severe collision risks by up to seven times compared to traditional driving, based on Tesla’s data from billions of global fleet miles. The session highlighted FSD’s role as an assistance tool in its Supervised form, not a replacement, with the driver fully responsible at all times.
Path to European rollout
Tesla has logged over 1 million kilometers of testing across 17 European countries, including Italy, to refine FSD for local conditions. The fact that Rome officials personally tested FSD Supervised bodes well for the program’s approval, as it suggests that key individuals are closely watching Tesla’s efforts and innovations.
Assessor Patanè also highlighted the administration’s interest in technologies that boost road safety and urban travel quality, viewing them as aids for both private and public transport while respecting rules.
Replies on X urged involving Italy’s Transport Ministry to speed approvals, with one user noting, “Great idea to involve the mayor! It would be necessary to involve components of the Ministry of Transport and the government as soon as possible: it’s they who can accelerate the approval of FSD in Italy.”
