Global Positioning System (GPS) satellite navigation could eventually be subject to a major upgrade as Elon Musks SpaceX has launched a satellite that promises to make GPS three times more accurate. Nevertheless, this doesnt necessarily mean that improvements will be seen overnight.

Usually taken for granted, GPS satellite navigation has become an essential tool for anything from military operations to a road trip. Every GPS device determines its position, navigation and timing information by receiving signals from a constellation of satellites orbiting the Earth 20,000 kilometers away.

The technology already works pretty well already and it feels like its always been there, despite its actually quite new, with the first such satellites launched in 1978 by the United States. Since then, many organizations have been involved in trying to refine it. Now, it was time for SpaceX to join that group.

Earlier this week, a Falcon 9 rocket delivered its first payload for the United States Space Force mission, carrying a state-of-the-art new GPS satellite. The mission sent up the third satellite for the so-called GPS III project, which seeks to upgrade the constellation of GPS satellites currently orbiting the planet.

Your GPS just got slightly better, Musk wrote on Twitter moments after the GPS III satellite was deployed. But thats not actually true since GPS doesnt get better automatically just because SpaceX launched a new satellite into space. Still, when more such satellites are deployed, the improvement should be more visible.

The current GPS technology can narrow down a location within 28 inches (about 71 centimeters). While thats quite an achievement, GPS III technology will narrow that range down even further, offering accuracy within nine inches (about 22 centimeters). Thats almost three times as accurate as now.

Coverage will also improve. This might mean that the dreaded searching for signal message on a cellphone while trying to get to a restaurant or a party could eventually be something of the past. Or maybe even forget about the difficulties of getting a GPS signal when you are in a forested or mountainous region during a hike.

The new satellites have a 15-year lifespan, which is twice as long as the current ones. They can be launched two at once, making them cheaper. And, most importantly, they will be harder to jam. So far, only one of the three that are in orbit is fully operational and the manufacturer Lockheed Martin is now building ten more.

GPS technology essentially uses signals from satellites in the sky to pinpoint the location of a user. A receiver, usually a smartphone, measures how long it took for a given satellites signal to reach Earth and then multiplies the time by the speed of a radio wave to work out the distance.

Nowadays GPS applications arent limited to simple, though widespread, auto-navigation, or as personal mapping; theyre used by manufacturing industries, supply chains, drilling oil, various other logistics, banks, and virtually anything you can imagine. A report warned in 2017 that the world might depend too much on the technology.

While the United States GPS constellation first started in 1978, the US is just one player in this global field. In 1982, the Soviet Union launched GLONASS, or Global Navigation Satellite System, and China followed with Beidou in 2000. Then came the European Space Agency with its first experimental satellite positioning system, Galileo, in 2005.

SpaceX launches new satellite that will make GPS three times more accurate (eventually) - ZME Science

Elon Musk and SpaceX never cease to amaze. Today we are dealing with one of those incredible ideas that are probably the fruit of the atypical CEOs mind. Indeed, the company is using a domestic robot (who has a lot of little house) to get help during his tests. Yes, you got it right.

In particular, according to what is reported by the Daily Mail and as you can see in the video published by the LabPadre YouTube channel, following the now-iconic explosion of the Starship SN7 test tank (made specifically to understand its limits), SpaceX has decided to send Zeus, a Boston Dynamics robot, to check for damage. In fact, carefully watching the video in which you see the tank, immediately after the explosion you see a figure moving near the involved area.

Some fans, therefore, wondered what it was, since it almost looked like a dog. Afterwards, the Twitter profile RGVAerialPhotography has published a photo that shows from above the place where SpaceX performed the test. Analyzing the photo, at the top right you can see it a yellow silhouette which refers in all respects to the robots of Boston Dynamics. As previously mentioned, the one used in this context seems to be called Zeus.

By the way, the operator of the Twitter profile Cooper_Hime managed to track down a house for Zeus in the test area of Elon Musks company. In short, there seems to be little doubt as to what the CEO of SpaceX is doing, that is, to use a robot so as not to risk the lives of human employees.
