SpaceX’s internet satellite strategy faces possible setback (Correction: It’s actually in great shape)

Published

on

Correction: Upon further analysis of FCC filings and proposed updates to ITU regulations, SpaceX’s Internet constellation is on much steadier ground than it initially appeared to be, and the FCC decision made on September 26 2017 to update its NGSO FSS regulations is likely to help SpaceX far more than it might harm the company. 

The ITU has since 2015 taken a stance that aligns more with the FCC’s cooperative spectrum sharing policy and did not intend for Part 5 of its Radio Regulations to be interpreted as a “first come, first serve” attitude. Specifically, the ITU’s 2017 Rules of Procedure pointedly state in Article 9.6 (Word document download) that those rules were not intended “to state an order of priorities for rights to a particular orbital position” and that “the [interference] coordination process is a two way process”. An ex parte filed with the FCC (PDF download) by SpaceX on September 15 stated SpaceX’s support for these international and domestic policy adoptions, as well as the FCC International Bureau’s responsive consideration of SpaceX’s own suggestions. 

The company’s first two test satellites could still launch later this year

The U.S. Federal Communications Commission (FCC) responded September 7th to requests for modification to existing satellite communications regulations and FCC practices from a number of prospective constellation operators, including OneWeb, Telesat, and SpaceX.

The FCC ultimately decided to avoid one major rule change that could force SpaceX to completely reconsider its strategic approach to its proposed Low Earth Orbit broadband constellation.

To grossly oversimplify, SpaceX had requested that the FCC apply their non-interference rules for lower orbit communications satellites to internet constellations operating both inside and outside the physical United States. These rules require that communication satellites operating in non-geostationary orbits (NGSO) share the available wireless spectrum equally among themselves when two or more satellites pass within a certain distance of each other relative to ground stations. In simpler terms, consider your smartphone’s cellular connectivity. The FCC’s rule for satellites in lower orbits can be thought of like multiple smartphones using the same cell tower to access the internet: the cell tower simply acknowledges the multiple devices it needs to serve and allows each device a certain amount of bandwidth.

However, the FCC is admittedly a domestic Commission focused on administering communications rules and regulations in the United States, and an agency already exists for coordinating global communications needs, called the International Telecommunication Union (ITU). The ITU’s Radio Regulations are considerably more simplistic. Rather than the FCC’s more nuanced and reasonable methods of spectrum sharing, the ITU allows the first satellite operator actively using a certain orbit or spectrum to become the primary coordinator for all interference issues. Put more simply, it gives those who launch communications satellites first a “first come, first serve” advantage that lets those entities then set the rules for interference with their constellation.

Both OneWeb and Telesat, companies also interested in launching global broadband constellations, are licensed in countries other than the United States, meaning that the FCC has given the ITU precedent in deciding how to deal with SpaceX’s potential constellation interference. SpaceX’s proposed constellation of at least several thousand satellites ends up being at a distinct disadvantage simply because it would take far longer for SpaceX to even partially complete its constellation when compared with competitors like OneWeb, who expect to finish launching the first phase of their constellation several hundred satellites by the end of 2020. Under the ITU’s regulations, SpaceX could be forced by competitors to effectively step on eggshells around their constellations by avoiding interference to the furthest extent possible, rather than simply sharing spectrum in the brief periods where different satellites temporarily interfere with each other.

While the FCC’s choice to cede international interference coordination to the ITU is a huge blow to SpaceX’s proposed internet constellation efforts, the same September 7th report also eased a handful of other requirements that would have proven difficult for SpaceX’s massive constellation. For geostationary constellations, the FCC previously required that all satellites be launched within a period of six years, with failure to do so resulting in a revoked license for the company in question. In a small concession to SES, O3b, and SpaceX, the FCC now plans to require that 50% of lower orbit satellite constellations be launched within six years of receiving an FCC license. This would still be a massive challenge for SpaceX’s plan of 4,425 initial satellites and a follow-up constellation of more than 7,000 additional satellites (PDF download).

The FCC’s September 7th report will not become final unless it is passed by vote in a September 26th Open Commission Meeting. It is possible that SpaceX council will make a statement protesting the FCC’s decision, but it is nevertheless likely that the FCC’s report will be accepted and become official. While the LEO internet constellation has remained a low priority for SpaceX since it was revealed in 2015, the company has steadily continued work on the project and SpaceX has every reason to continue pursuing it given the potential profit margins it could produce. In spite of the now expanded difficulties lying ahead, SpaceX appears to be preparing for the first launch of two test satellites related to its internet constellation efforts. The move is seen as a likely attempt to tag along as passengers during SpaceX’s launch of PAZ, a Spanish earth imaging satellite, during the final three months of 2017.

Elon Musk is scheduled to reveal more details on SpaceX’s Mars exploration and colonization efforts on September 29th. He has stated that this presentation will focus more on the “how” of colonizing Mars, revealing how exactly SpaceX thinks it can fund the development of its Interplanetary Transport System. Musk also confirmed several weeks ago that SpaceX had reduced the size of the ITS rocket to a still-massive diameter of 9 meters, and sources inside the company have also indicated that the company is thinking about modifying its LC-39A Florida launch pad to support both Falcon and ITS vehicles. SpaceX recruiters revealed earlier this week that SpaceX also intends to have their Boca Chica, Texas launch pad, which is currently under construction, be capable of eventually launching ITS-sized vehicles once it comes online in 2019 or later.

Tesla already has a complete Robotaxi model, and it doesn’t depend on passenger count

That scenario was discussed during the company’s Q4 and FY 2025 earnings call, when executives explained why the majority of Robotaxi rides will only involve one or two people.

Tesla already has the pieces in place for a full Robotaxi service that works regardless of passenger count, even if the backbone of the program is a small autonomous two-seater. 

That scenario was discussed during the company’s Q4 and FY 2025 earnings call, when executives explained why the majority of Robotaxi rides will only involve one or two people.

Two-seat Cybercabs make perfect sense

During the Q&A portion of the call, Tesla Vice President of Vehicle Engineering Lars Moravy pointed out that more than 90% of vehicle miles traveled today involve two or fewer passengers. This, the executive noted, directly informed the design of the Cybercab. 

“Autonomy and Cybercab are going to change the global market size and mix quite significantly. I think that’s quite obvious. General transportation is going to be better served by autonomy as it will be safer and cheaper. Over 90% of vehicle miles traveled are with two or fewer passengers now. This is why we designed Cybercab that way,” Moravy said.

Elon Musk expanded on the point, emphasizing that there is no fallback for Tesla’s bet on the Cybercab’s autonomous design. He reiterated that the autonomous two seater’s production is expected to start in April and noted that, over time, Tesla expects to produce far more Cybercabs than all of its other vehicles combined.

“Just to add to what Lars said there. The point that Lars made, which is that 90% of miles driven are with one or two passengers or one or two occupants, essentially, is a very important one… So this is clearly, there’s no fallback mechanism here. It’s like this car either drives itself or it does not drive… We would expect over time to make far more CyberCabs than all of our other vehicles combined. Given that 90% of distance driven or distance being distance traveled exactly, no longer driving, is one or two people,” Musk said. 

Tesla’s robotaxi lineup is already here

The more interesting takeaway from the Q4 and FY 2025 earnings call is the fact that Tesla does not need the Cybercab to serve every possible passenger scenario, simply because the company already has a functional Robotaxi model that scales by vehicle type.

The Cybercab will handle the bulk of the Robotaxi network’s trips, but for groups that need three or four seats, the Model Y fills that role. For higher-end or larger-family use cases, the extended-wheelbase Model Y L could cover five or six occupants, provided that Elon Musk greenlights the vehicle for North America. And for even larger groups or commercial transport, Tesla has already unveiled the Robovan, which could seat over ten people.

Rather than forcing one vehicle to satisfy every use case, Tesla’s approach mirrors how transportation works today. Different vehicles will be used for different needs, while unifying everything under a single autonomous software and fleet platform.

Tesla Cybercab spotted with interesting charging solution, stimulating discussion

Tesla Cybercab units are being tested publicly on roads throughout various areas of the United States, and a recent sighting of the vehicle’s charging port has certainly stimulated some discussions throughout the community.

The Cybercab is geared toward being a fully-autonomous vehicle, void of a steering wheel or pedals, only operating with the use of the Full Self-Driving suite. Everything from the driving itself to the charging to the cleaning is intended to be operated autonomously.

But a recent sighting of the vehicle has incited some speculation as to whether the vehicle might have some manual features, which would make sense, but let’s take a look:

The port is located in the rear of the vehicle and features a manual door and latch for plug-in, and the video shows an employee connecting to a Tesla Supercharger.

Now, it is important to remember these are prototype vehicles, and not the final product. Additionally, Tesla has said it plans to introduce wireless induction charging in the future, but it is not currently available, so these units need to have some ability to charge.

However, there are some arguments for a charging system like this, especially as the operation of the Cybercab begins after production starts, which is scheduled for April.

Wireless for Operation, Wired for Downtime

It seems ideal to use induction charging when the Cybercab is in operation. As it is for most Tesla owners taking roadtrips, Supercharging stops are only a few minutes long for the most part.

The Cybercab would benefit from more frequent Supercharging stops in between rides while it is operating a ride-sharing program.

Tesla wireless charging patent revealed ahead of Robotaxi unveiling event

However, when the vehicle rolls back to its hub for cleaning and maintenance, standard charging, where it is plugged into a charger of some kind, seems more ideal.

In the 45-minutes that the car is being cleaned and is having maintenance, it could be fully charged and ready for another full shift of rides, grabbing a few miles of range with induction charging when it’s out and about.

Induction Charging Challenges

Induction charging is still something that presents many challenges for companies that use it for anything, including things as trivial as charging cell phones.

While it is convenient, a lot of the charge is lost during heat transfer, which is something that is common with wireless charging solutions. Even in Teslas, the wireless charging mat present in its vehicles has been a common complaint among owners, so much so that the company recently included a feature to turn them off.

Production Timing and Potential Challenges

With Tesla planning to begin Cybercab production in April, the real challenge with the induction charging is whether the company can develop an effective wireless apparatus in that short time frame.

It has been in development for several years, but solving the issue with heat and energy loss is something that is not an easy task.

In the short-term, Tesla could utilize this port for normal Supercharging operation on the Cybercab. Eventually, it could be phased out as induction charging proves to be a more effective and convenient option.

Tesla has confirmed that it is now producing both the anode and cathode of its 4680 battery cells using a dry-electrode process, marking a key breakthrough in a technology the company has been working to industrialize for years. 

The update, disclosed in Tesla’s Q4 and FY 2025 update letter, suggests the company has finally resolved one of the most challenging aspects of its next-generation battery cells.

Dry cathode 4680 cells

In its Q4 and FY 2025 update letter, Tesla stated that it is now producing 4680 cells whose anode and cathode were produced during the dry electrode process. The confirmation addresses long-standing questions around whether Tesla could bring its dry cathode process into sustained production.

The disclosure was highlighted on X by Bonne Eggleston, Tesla’s Vice President of 4680 batteries, who wrote that “both electrodes use our dry process.”

Tesla first introduced the dry-electrode concept during its Battery Day presentation in 2020, pitching it as a way to simplify production, reduce factory footprint, lower costs, and improve energy density. While Tesla has been producing 4680 cells for some time, the company had previously relied on more conventional approaches for parts of the process, leading to questions about whether a full dry-electrode process could even be achieved.

4680 packs for Model Y

Tesla also revealed in its Q4 and FY 2025 Update Letter that it has begun producing battery packs for certain Model Y vehicles using its in-house 4680 cells. As per Tesla: 

“We have begun to produce battery packs for certain Model Ys with our 4680 cells, unlocking an additional vector of supply to help navigate increasingly complex supply chain challenges caused by trade barriers and tariff risks.”

The timing is notable. With Tesla preparing to wind down Model S and Model X production, the Model Y and Model 3 are expected to account for an even larger share of the company’s vehicle output. Ensuring that the Model Y can be equipped with domestically produced 4680 battery packs gives Tesla greater flexibility to maintain production volumes in the United States, even as global battery supply chains face increasing complexity.
