SpaceX's Elon Musk says Starlink user antennas will be like "UFOs on a stick"

Published

SpaceX CEO Elon Musk has teased the first detailed description of the Starlink antennas (“user terminals”) customers will need to connect to the massive satellite internet constellation, revealing a few new and unexpected details about the critical hardware.

Although nearly all public focus is currently (and understandably) on the production and launch of Starlink satellites themselves, that perspective actually glosses over a second element of the constellation that is at least as important. Starlink, after all, is designed to delivered high-speed, low-latency broadband internet to customers around the world, and that service will not just magically appear in the houses of interested consumers. Similar to satellite TV, customers will gain access to their Starlink internet service with an antenna that will have to be installed somewhere on or around the premises.

The challenge that SpaceX faces with the grounded side of Starlink is that – unlike the geostationary satellites that provide satellite TV – satellites in low Earth orbit (LEO) are visible from a specific point on the ground for just a handful of minutes each. Whereas satellite TV dishes simply need to be pointed at one unmoving spot in the sky, Starlink ground antennas will need to constantly change where they are pointed (or at least track constantly-moving and changing satellites) and do so seamlessly and with incredible reliability.

A step further and even more importantly, while SpaceX unequivocally needs to make its Starlink user terminals extremely capable, simple, and reliable, it will also need to find a way to mass-produce millions (ultimately tens to hundreds of millions) of units and keep the cost to consumers unprecedentedly low. At least before Musk’s January 7th, 2020 comment, it was believed that Starlink user terminals would have to rely almost entirely on high-performance phased-array antennas, referring to antennas that are steered electronically – i.e. without physically moving.

100% phased-array steering would likely result in the best possible user terminal from the standpoint of reliability and performance. However, full phased-array antennas – while making rapid progress – are still extremely expensive to manufacture compared to more basic alternatives, meaning that it could be an immense challenge – possibly much harder than building and launching Starlink satellites themselves – to mass-produce affordable user terminals under that paradigm. It’s possible that SpaceX has actually come to the same conclusion and is choosing to compromise with its first-generation user terminals, prioritizing time to market and cost per unit at the expense of peak performance and optimal reliability.

Competitor OneWeb may actually have a step up on SpaceX on that front, having reportedly already made great progress developing an exceptionally cheap flat-panel phased-array antenna capable of at least decent throughput (10-50 Mbps). On January 7th, Musk revealed that the current iteration of Starlink user terminals look like a “thin, flat, round UFO on a stick” and features “motors to self-adjust [and ensure it’s at the] optimal angle to view [the] sky.”

The latter tidbit came as a bit of a surprise, given that nearly all cutting-edge phased-array antennas in development feature flat-panel designs and mounting hardware and pointedly avoid mechanical steering – one of the great benefits of phased arrays. It’s ultimately unclear what purpose a mechanical pointing motor would serve on a Starlink user terminal. If the terminal is centered around a true phased-array antenna, mechanical steering would be an almost vestigial addition. However, it’s possible that SpaceX has found a way to hybridize electronic (phased-array) and mechanical steering to produce user terminals that are exceptionally cheap and high-performance at the cost of a reliability risk (moving parts).

Ultimately, it looks like we will find out much sooner than later how exactly SpaceX’s Starlink user terminals work, among other details. Musk says that Starlink will be able to start serving customers in Canada and the Northern US with as few as four additional Starlink launches, meaning that some form of beta test could begin after Starlink V1 L6.

As of now, SpaceX has 1-2 more Starlink missions scheduled to launch later this month. If SpaceX averages two launches per month, Starlink could be serving its first customers as early as March or April 2020.

Tesla Phone? Not quite, but close: analyst

For years, there have been images and videos across social media platforms that have reminded me of when I was a 15-year-old kid teased by “Xbox 720” videos on YouTube. These videos are of the supposed “Tesla Phone” that Elon Musk was secretly developing in between leading Tesla with its electric cars and SpaceX with its reusable rockets.

Although Musk has put those rumors to bed several times, it was never completely out of the realm that he could get involved in cell phones in some capacity. Think outside the box and more macro-level, though. Instead of reinventing the computer, Musk reinvented connectivity by developing Starlink with SpaceX.

It could be something similar, TD Cowen analyst Gregory Williams said in a note last week, where he hinted SpaceX could be gathering some steam to acquire T-Mobile.

Williams said it would be the “clear choice” for SpaceX if it decided to go through with a network acquisition. He also suggested AT&T.

The move would be possible through selling more of its own stock, which would help SpaceX raise the money to purchase T-Mobile, which would cost roughly $300 billion. It could be one of the moves SpaceX makes post-IPO in terms of an acquisition: it already acquired Cursor AI for $60 billion.

Other analysts, like Dan Ives of Wedbush, believe SpaceX and Tesla will eventually merge into one anyway, and that conglomeration could come as soon as this year, some have said.

The implications of SpaceX purchasing T-Mobile are massive. A combined entity would create a truly ubiquitous network: T-Mobile’s terrestrial 5G towers and Starlink’s growing constellation of Direct-to-Cell satellites. This would essentially eliminate dead zones across the U.S. and potentially globally.

SpaceX would instantly become a full-scale facilities-based carrier with satellite differentiation; a huge advantage. This would pressure AT&T and Verizon heavily.

There are also concerns like a potential reduction in long-term competition, and of course, a deal of that size would face intense scrutiny from government agencies.

The strategic fit is compelling due to the existing Starlink–T-Mobile partnership and complementary technologies (space + terrestrial). It could create a dominant integrated communications player. However, the regulatory, financial, and execution hurdles are enormous — this remains highly speculative with no indication SpaceX is actively pursuing it right now.

Tesla revealed a major new Cybercab detail in a guide it released for First Responders, showing new territory in its beliefs and intentions for the ride-hailing-focused vehicle that entered production in April.

The First Responders Guide is released to give fire departments, paramedics, and other emergency personnel the proper guidance on what to do in the event of an accident, entrapment, or other situation that would require immediate attention.

On one of the pages of the First Responders Guide, Tesla revealed a stark detail about the Cybercab, which could help personnel enter the vehicle more easily in case of an emergency.

Tesla Cybercab has one important piece that AI4 cars might need for FSD

It shows Tesla has no intention of releasing any Cybercab units that were initially proposed for ride-hailing services for the general public with any manual controls, meaning a steering wheel or pedals:

“A Cybercab equipped with steering wheel, brake pedal, and an acceleration pedal is typically an engineering or test vehicle, and operates at SAE Level 2 autonomy. Cybercab is not typically equipped with a steering wheel or acceleration and brake pedals.”

This is a major development for those who continue to believe Tesla planned to release the Cybercab with any sort of manual controls so that passengers could take over if needed. However, when Tesla started manufacturing production versions of the Cybercab in Giga Texas earlier this year, they were spotted without a steering wheel or pedals.

It essentially confirms the company has no intentions of bringing manual controls to the car’s production versions. Some have argued that the likelihood of Tesla having something

There still are some Cybercab units out there with a steering wheel and pedals, and as Tesla said, these cars are engineering or test vehicles, which have Safety Monitors on board to help the car out of a precarious situation or emergency.

Tesla released the Full Self-Driving v14 ‘Lite’ suite to owners of Hardware 3 or AI3 vehicles today, adding several new features to the vehicles that were once believed to be capable of unsupervised self-driving.

Now, Tesla has released this modified suite to older Tesla vehicles, adding plenty of new features and capabilities.

Here are the full release notes for the suite:

  • Distilled the intelligence from HW4 V14 into HW3. This allows HW3 to directly learn how to handle scenarios using HW4 V14 as a guide. This process unlocks the improvements that have been made to HW4 including Reinforcement Learning (RL) and offline models for HW3.
  • Improved both proactive and reactive responsiveness across a wide variety of categories including navigation handling, merges and forks, pedestrian interactions, traffic lights, and vehicle cut-in scenarios.
  • Improved general comfort in nominal scenarios through fewer false slowdowns, smoother steering and more consistent lane centering.
  • Introduced parking, unparking, and reversing capabilities.
  • Added Arrival Options for you to select where FSD should park: in a Parking Lot, on the Street, in a Driveway, or at the Curbside.
  • Speed Profiles are now available at all times, to further customize driving style preference.

These improvements, according to Tesla’s Head of AI, Ashok Elluswamy, help distill the driving behavior from AI4’s v14 series into both the camera and compute configurations of AI3.

Tesla Full Self-Driving v14 ‘Lite’ for older cars finally gets released

He added:

“It includes destination options and speed profiles on city roads, but more importantly significantly improved safety. We hope you’ll enjoy it, once the build ships wide.”

Tesla will continue to roll out the v14 Lite suite more widely in the coming weeks, the company said.
