GPS on the moon: Spanish firm launches lunar navigation system

By Borja Suárez
MADRID (Reuters) -Spanish technology company GMV has unveiled a GPS-like navigation system for the moon that aims to make lunar missions as intuitive as a drive across town with apps such as Google Maps or Waze.
Called LUPIN, the project is part of a programme by the European Space Agency to test new positioning, navigation and timing techniques as interest in lunar surface exploration picks up again, whether for scientific research, potential mining opportunities or even future tourism.
"With this software, we bring Europe closer to establishing a presence of humans on the moon and, potentially, this would be a stepping stone towards Mars exploration or human presence on Mars," Steven Kay, the project's director, told Reuters.
The new technology was put to the test in the otherworldly landscapes of Fuerteventura - one of Spain's Canary Islands - where GMV conducted field trials with the prototype in a part of the Earth that bears some resemblance to the lunar surface.
By using signals similar to GPS from moon-orbiting satellites, LUPIN would allow rovers and astronauts to pinpoint their location on the moon in real time.
Currently, navigating the Earth's largest natural satellite is difficult, as spacecraft on its surface have to rely on complex calculations and data relayed from Earth - which is neither quick nor precise.
"Communication depends on direct visibility with Earth or the use of relay satellites in lunar orbit, which create communicative shadow zones and latency times that hinder immediate decision-making," GMV said in a statement.
The lack of real-time updates on changes in the moon's terrain caused by recent impacts or lunar dust movements also hinder ground trips on the satellite.
The company wants to combine existing lunar cartography with information gleaned from moon-orbiting satellites targeting dark spots, such as the lunar south pole and the "far side", the area generally in shadow.
"We want these rovers to map the surface of the moon in a fast and safe way so that astronauts can return in a few years, work there and set up permanent bases," said GMV's head of strategy, Mariella Graziano.

Musk's Tesla is launching robotaxis in Austin, Texas

After driverless Tesla Model Ys were spotted traversing Austin, Texas, streets on Sunday morning, CEO Elon Musk posted on his social platform X that Tesla's "robotaxi launch" would start this afternoon with rides for a flat fee of $4.20. A Reuters witness saw several Tesla "robotaxis" on Sunday morning in a popular area of the Texas capital called South Congress with no one in the driver's seat but one person in the passenger seat. Tesla planned to have front-seat riders acting as "safety monitors," though it remained unclear how much control they would have over the vehicles. Videos of driverless Teslas have also been posted on social media but it was not known if the vehicles carried any passengers. As the date of the planned robotaxi launch approached, Texas lawmakers moved to enact rules on autonomous vehicles in the state. Texas Gov. Greg Abbott, a Republican, on Friday signed legislation requiring a state permit to operate self-driving vehicles. The law does not take effect until Sept. 1, but the governor's approval of it on Friday signals state officials from both parties want the driverless-vehicle industry to proceed cautiously. A group of Democratic state lawmakers earlier this week asked Tesla to delay its planned robotaxi trial because of the legislation. Tesla did not respond to requests for comment. The governor's office declined to comment. The law softens the state's previous anti-regulation stance on autonomous vehicles. A 2017 Texas law specifically prohibited cities from regulating self-driving cars. In recent days, Tesla has sent invites to a select group of Tesla online influencers for a small and carefully monitored robotaxi trial, which the company has said would include 10 or 20 Model Y vehicles operated in a limited zone of Austin. The law requires autonomous-vehicle operators to get approval from the Texas Department of Motor Vehicles before operating on public streets without a human driver. It also gives state authorities the power to revoke permits if they deem a driverless vehicle "endangers the public," and requires firms to provide information on how police and first responders can deal with their driverless vehicles in emergency situations. The law's requirements for getting a state permit to operate an "automated motor vehicle" are not particularly onerous but require a firm to attest it can safely operate within the law. It defines an automated vehicle as having at least "Level 4" autonomous-driving capability under a recognized standard, meaning it can drive itself with no human driver under specified conditions, such as within a limited area. Level 5 autonomy is the top level and means a car can drive itself anywhere, under any conditions. Compliance remains far easier than in some states, most notably California, which requires extensive submission of vehicle-testing data under state oversight. The Tesla robotaxi launch, which the company warned might be delayed, comes after more than a decade of Musk's unfulfilled promises to deliver self-driving Teslas. Most of Tesla's sky-high stock value now rests on its ability to deliver robotaxis and humanoid robots, according to many industry analysts. Tesla is by far the world's most valuable automaker. Musk has said Tesla would be "super paranoid" about safety for the Austin rollout. The company planned to operate only in areas it considered the safest. The service in Austin will have other restrictions as well. Tesla plans to avoid bad weather, difficult intersections, and will not carry anyone below the age of 18. Musk has said he is ready to delay the start for safety reasons, if needed. The planned launch has generated buzz among Tesla fans. "Wow. We are going to ride in driverless Teslas in just a few days. On public roads," posted Omar Qazi, who has 635,200 followers on X, writes often about Tesla using the handle @WholeMarsBlog, and received an invite. Commercializing autonomous vehicles has been risky and expensive. GM's Cruise was shut down after a fatal accident and regulators are closely watching Tesla and its rivals, Alphabet's Waymo, which runs a paid robotaxi service in several U.S. cities, and Amazon's Zoox. Tesla is also bucking the young industry's standard practice of relying on multiple technologies to read the road, using only cameras. That, Musk says, will be safe and much less expensive than lidar and radar systems added by rivals.

Google killed Maps Timeline, so I self-hosted a better one

Dhruv Bhutani / Android Authority As an avid traveler, Google Maps Timeline has long been one of my favorite hidden features. I'm used to opening it on slow Sunday afternoons and wandering through my own travel history. It showed alleyways I had forgotten, long layovers that blurred together while stepping out for a quick brunch across a new city, and impulsive last-minute rail journeys across Eastern Europe that never made it into photos. It's always felt like a private travel diary logging everywhere I've been. So the announcement that Google will be killing Timeline view as we know it came as a bit of a shock. The online timeline view is no longer accessible, and the only copy lives on your phone — unless you explicitly trigger a cloud backup. As with all things Google, if a feature is too good, it eventually gets killed (even if it's in the name of privacy). For all practical purposes, Google was about to move a decade and a half of my location history behind a Takeout export. In other words, I could download my past travels or watch them vanish. If I cared about those memories, it was clear that I had to figure out a way to take ownership of that data. So I did the obvious: I looked up a self-hosted alternative. Even at first glance, OwnTracks looked like the right tool. It's open source, it works entirely on personal infrastructure, and it stores data in plain text. The interface is reasonably polished, and there's no hidden monetization. All of which is exactly what I wanted in a Google Maps Timeline replacement. Setting it up took a weekend of tinkering on my Synology NAS, but the payoff was a location log that lives on hardware I've already paid for. I can choose what to do with that data, including integrating it with Home Assistant, and I can back it up wherever and as often as I like. Win-win. Setting up OwnTracks and importing my old Maps data Dhruv Bhutani / Android Authority Getting started with OwnTracks is an involved process, so I began with the basics. It needs an MQTT broker to shuttle messages between the phone app and the server. I installed Eclipse Mosquitto in a Docker container. The documentation is clear enough about ports and volume mounts. Once the broker was running, I pointed the OwnTracks app on my Pixel 9 Pro to the NAS's LAN IP and watched as JSON packets began appearing in the logs. While I'm fine with syncing my location history whenever I'm back home, you can also set up a reverse proxy and update your location in real time. Perhaps a project for another time. The second step was storage and playback. OwnTracks is split into two parts: the recorder, which, well, records your location, and the frontend, which displays it. The recorder connects to the MQTT broker we installed earlier, writes every update to disk, and exposes an HTTP API. Installing it was straightforward with Docker Compose, and you can also use Synology's Container Manager for an even easier setup. By default, the recorder serves a basic map on port 8083. It's not flashy, but it works. I saw my evening walk pop up almost in real time. And if you're just looking to log your location from here on out, you can skip the frontend altogether. If importing your Timeline history is important to you, like it was to me, you'll want to continue installing the frontend. The process is similar to installing the recorder and shouldn't take over an hour. Installing OwnTracks wasn't frictionless, but once it worked, it felt like stepping back into Google's old timeline view. Except this time, everything was self-hosted. Paired with the OwnTracks app on Android or iOS, the system also works offline. If the internet drops or you haven't set up external access, the data still lands on your NAS or home server as soon as your phone reconnects to the MQTT broker. It has to be said that Google does not make it easy to import your old location data. After running the export through Google Takeout, importing my old data took quite a bit of wrangling. Takeout handed me a folder of JSON files, and it took a community script to convert those into the format the recorder expects. Once that was done, I piped in a decade's worth of travels over to OwnTracks, restarted the service, and watched as it quietly added everything into the database. It wasn't frictionless, but once it worked, it felt like stepping back into Google's old timeline view, except this time, everything was self-hosted. Taking ownership of your personal data Dhruv Bhutani / Android Authority Despite the effort involved in setting up OwnTracks, the end result makes it worth it. The process taught me all the variables that go into getting the service running and reminded me why self-hosting feels liberating. If I ever need to troubleshoot things, it should be fairly trivial, and every fix is more or less final. I can choose to never update the service until a major release. More specifically, Google can't mark my NAS as deprecated. Which, you'd have realised by now, is a feature in itself. Additionally, if I want to tweak something, I can read the source code and add it in. Coming to the experience of using OwnTracks, it, predictably, isn't as full-featured as a product by Google. All you get is a map with location markers showing where you've been. Since the service leverages OpenStreetMaps, the data isn't as full-featured either. So, this might not be your best bet if you're trying to pinpoint an old restaurant you visited a decade ago, or expect add-ons like Street View to walk back in your own steps. Self-hosting gives me a private and more permanent solution for my location history timeline, and it's totally under my control. But for all its limitations, OwnTracks does a great job of helping you visualize where you were at a specific point in time. Depending on your needs, that might be enough. While OwnTracks doesn't offer heatmaps or trip labels, it does offer something more important: permanence. The data sits in JSON files, neatly organized by year and month. Any mapping library can read it. If I want a heatmap, I can generate one with Python in five minutes. There's a lot of flexibility here. Of course, privacy is the other most obvious win. Nothing leaves my network unless I push it. The recorder supports end-to-end encryption with a pre-shared key, so even if I sync data between sites, the raw coordinates stay protected. No analytics. No third-party servers unless I choose to use them. Since the service is fairly lightweight, hardware requirements have also been modest. You could run this on a spare Raspberry Pi if you choose to. MQTT and the recorder together use less than one percent CPU on a five-year-old NAS. The frontend is just Nginx serving static files. A full year of movement data, logged at ten-second intervals, weighs in at just a few hundred megabytes. That's a very tiny footprint, all things considered. I've also layered on additional conveniences for more peace of mind. For example, the location data gets backed up nightly not just to a second NAS, but also to — ironically — Google Drive. Is this for everyone? Dhruv Bhutani / Android Authority Could a less technically inclined friend replicate this? Probably, if they're comfortable using Docker Compose and a terminal. OwnTracks is not plug-and-play, but community write-ups help fill in the gaps. There are guides for Synology, Unraid, Raspberry Pi, and plain Linux. And the tooling improves each year. But I'd be kidding if I said it was easy. In an ideal world, we shouldn't have to run a service like this. But with Google's ham-fisted approach toward beloved services, it's probably for the best. If Google brings back the old Timeline tomorrow, I'd still stick with OwnTracks for its permanence. I'm not claiming OwnTracks is perfect. The mobile app occasionally stops publishing when Android's battery manager gets too aggressive. The map viewer lacks search. Importing large datasets can freeze the UI until processing completes. But these are tradeoffs I can live with. They're also not serious enough to impede usage. All that said, location history feels trivial until you lose it. Sometimes, the only record of a detour or a missed turn that led you to a cool spot is a dot on a map. That dot can jog a memory or simply remind you that you covered a lot of ground that year. Now that dot lives permanently on my NAS. If Google brings back Timeline tomorrow, I'd still stick with OwnTracks because of that permanence.
