Fundamental physics—let alone quantum physics—might sound complicated to many, but it can actually be applied to solve everyday problems. Imagine navigating to an unfamiliar place. Most people would suggest using GPS, but what if you were stuck in an underground tunnel where radio signals from satellites were not able to penetrate? That's where quantum sensing tools come in. USC Viterbi Information Sciences Institute researchers Jonathan Habif and Justin Brown, both from ISI's new Laboratory for Quantum-Limited Information, are working at making sensing instruments like atomic accelerometers smaller and more accurate so they can be used to navigate when GPS is down.

What is GPS ?

GPS stands for Global Positioning System. It is a satellite-based navigation system that allows users to determine their precise location and track their movement on the Earth's surface. The system provides information on latitude, longitude, altitude, and the current time at the user's location.

The GPS system consists of a network of satellites in orbit around the Earth. These satellites transmit signals to GPS receivers on the ground or in devices like smartphones, cars, and other navigation systems. The GPS receiver uses the signals from multiple satellites to calculate the user's precise location through a process called trilateration.

The accurate positioning information provided by GPS has a wide range of applications, including navigation for vehicles, aircraft, and ships, tracking and mapping, surveying, and various location-based services such as geotagging in photos and finding nearby points of interest. GPS has become an essential tool in both civilian and military applications, significantly impacting various aspects of daily life.

Truck Platooning Market Analysis by Trends, Size, Share, Growth Opportunities, and Emerging Technologies

It is common to hear in the news that a truck met with an accident, and the truck driver got badly injured or died. According to the data of National Safety Council, 5700 large trucks were involved in a fatal crash in 2021, which was 18% more than the preceding year.

So, the challenges involved in the day-to-day job of a truck driver on the job is a big reason for the shortage of labor in the industry. Trucking also involves long, hours spent squeezed into a cab. There are strict deadlines to be met, and this job requires the utmost attention. It is important that quality of life of the trucker should be improved, and truck platooning can surely help you with the way forward.

It is a Semi-Autonomous Approach

If you talk about platooning, it does not replace the existing trucks with a driverless solution, so, it is clear that it is not about full autonomy. Yes, you can always think of platooning as a strategy, which is made possible with the help of the developments in the field of connected driving.

Platooning is when many trucks, in the guidance of a lead truck can follow each other closely. These can accelerate, break, and take a turn while semi-automatic features in the lead truck reduces the probability of human error. Although, the lead truck is controlling the fleet, the following trucks will also have drivers so that they can complete their scheduled deliveries, by breaking the chain.

Fuel Costs are Reduced Considerably

It is not just about enhanced safety but, platooning can do good for the truck drivers and the trucking companies as well. By letting trucks to drive in close proximity, there is a reduction of the aerodynamic drag and the space taken by the trucks on the road, reducing the costs of fuel.

Room For Relaxation on the Roads

This might spring a surprise to many that how it is possible to have a room for relaxation, and that too while driving such a heavy vehicle, like truck. But, believe me it is true.

Platooning also enhances the experience of trucking. Drivers in the trucks, following the lead feel comfortable because of the presence of technology. It allows them to take their foot of the pedal and relax.

The Concept of Tele-Trucking

With the improvement in technology, platooning could transform the trucking industry. Drivers can monitor and operate their trucks remotely. And many drivers could work from the same room, decreasing the level of loneliness.

There is often a threat to people with technology, that it could replace people but it is too hard to be true. With the implementation of truck platooning, it will not replace people, but it would take out the dullness from their jobs and make it more enjoyable.

Final Sum Up

It is quite clear that due to the need for safer road transport by the people, and to make the life of the truckers a bit easier, the demand for truck platooning will continue to advance in the future.

Yeah, I get the question (and sometimes the brand names are jarring!) but the specific alternatives here sounded weird for me. If this is supposed to be set in the 2020s I'd say "she put the address into her phone map" (perhaps "phone map app", or just "map app" because apps are supposed to be on phones anyway*) or maybe something like "asked her phone for directions" - which would be conveniently ambiguous between Google, Yandex, Waze, and a bunch of other more marginal options. (I do have to admit that "she set her Google Maps to give directions" would sound a bit like product placement unless it's deliberately intended to be a detailed look. I'd be fine with something like "she put the address into Google Maps", though.)

When I read "she put the address in her GPS" I'm imagining a standalone GPS device that was 1) advanced enough to put an address into (I believe there used to be specific CDs with the databases...) and 2) not yet just part of the smartphone. So, yes, 00s to mid-10s (and it was probably a Garmin). (Side-note: technically, GPS is supposed to be another brand rather than a generic term (competing with e.g. Glonass), and modern "GPS" devices actually use several of those systems at once! But the genericization on that one had bolted long ago and if you say "GPS" you'd be understood better than if you tried to look for actual generic terms.)

More generically (...somewhat following on to the GPS point just above), sometimes you have a problem where the brand name is so much more familiar that using the generic name for whatever service it is would just look weird! If it would even be intelligible at all.

Suppose that you don't want to say Twitter in your 2024 book because you don't think your 2026 or 2036 readers would know what Twitter is. (I'm using Twitter as an example because it's one case where it would actually be plausible that in a few years there'd be people unfamiliar with the brand name, but conveniently it also makes the following point easier to state.) What would you use? "Microblog" (or, worse, "microblogging service") would sound ridiculous. "Social media" is too generic (unless you want your readers to assume it's Facebook). "Mastodon" is even more specific (and might not necessarily be a recognizable thing in 2030 either). "X" could easily be just as unintelligible in the future (especially if it's later renamed to something else again) and in the meantime it makes you look like a Musk fanboy. So pretty much you'd need to either make up a brand (and hope it's not the actual name of something unrelated) or give in and say Twitter.

OTOH if your characters are using Twitter (or Google - Maps or otherwise - or Siri, or Facebook, or Discord, or indeed Tumblr... or, in one unfortunate example that comes to mind, MySpace) in, say, 2231 (or some other blatantly-far-future date), then either you're deliberately making a point about the persistence of existing brands, or you should probably change that to something less time-specific, and/or something made up for the story. (I'll give "GPS" a pass, unless it's set on another planet. Even then it's probably not that bad of a choice.)

And as a final side-note - I do love it when a story set in a particular time period uses authentic technology and recognizable brand names for that time period.

It's great if your characters in 2006 are posting on MySpace and putting addresses in MapQuest! (Though they probably wouldn't be doing it on their phones...) If anything it's more jarring if the story uses a brand name (or other technology) that didn't actually exist in the relevant time period (no, Rowling, there were no PlayStations in 1994, or not in the UK anyway).

(BTW, I voted for the third option in the poll, because it was a convenient "it depends" option that didn't really hinge on whether Google and GPS were in fact the same thing. Which they aren't, but not for the reason that the OP was trying to imply.)

*) unless you're Discord and don't like the word "bot" for some reason

Reading a book now that in the same few paragraphs mentioned Siri, google maps, and another app all at once, and I was kind of overwhelmed by how specific that is—to Apple, to right now, etc. I got bogged down in wondering if that section would be legible in 15 years, like if Siri goes away or is renamed or no one uses Apple phones.

What are your thoughts on books including specific app or brand names, which might end up dating it (like all books with “twitter” in them are now Pre 2024 books)?

Aka, would you prefer to write/read “she set her google maps to give directions” or “she put the address in her gps.”

Satellites: Their Orbits, Tracking Systems, and Essential Uses

Satellites: Their Positions, Tracking, and Importance

Satellites have become an essential part of modern life, orbiting Earth and providing us with services ranging from communication and navigation to weather forecasting and space exploration. As of 2024, thousands of active satellites are circling our planet, each performing a specific role to enhance the quality of life on Earth. This article delves into the positioning of satellites, how they are tracked, what they track, and the significance of their roles.

Types of Satellite Orbits and Their Positions

Satellites are positioned in various orbits depending on their intended functions. These orbits determine how close the satellite is to Earth, how fast it moves, and what areas it covers.

Low Earth Orbit (LEO): Altitude: 180 km to 2,000 km Satellites in LEO include most Earth observation satellites, the International Space Station (ISS), and some communication satellites. These satellites are closer to the Earth, enabling them to capture high-resolution images. Functions: Used for imaging, remote sensing, and some communication purposes. Examples: ISS, Earth observation satellites like Landsat.

Medium Earth Orbit (MEO): Altitude: 2,000 km to 35,786 km Satellites in MEO are mainly used for navigation. This orbit offers a good balance between coverage and latency. Functions: GPS satellites and other global navigation systems. Examples: GPS, GLONASS, and Galileo satellites.

Geostationary Orbit (GEO): Altitude: 35,786 km above the equator Satellites in GEO move at the same rotational speed as Earth, meaning they stay fixed over one location on Earth. These are mostly communication and weather satellites. Functions: Used for television broadcasts, weather monitoring, and some types of communication. Examples: Weather satellites (GOES series), telecommunication satellites.

Highly Elliptical Orbit (HEO): Orbit shape: An elongated orbit with one point closer to Earth (perigee) and another point much farther away (apogee). Functions: Ideal for regions at high latitudes, providing prolonged coverage over areas like Russia and parts of Canada. Examples: Molniya satellites for communication in Russia.

How Satellites Are Tracked

The sheer number of satellites in space, combined with space debris, means tracking them is essential to avoid collisions and ensure their functionality. Ground stations and dedicated space agencies continuously monitor satellites. Several methods are used to track satellites:

Radar and Ground-Based Systems: Ground stations use radar to track satellites in LEO. These systems bounce radio waves off the satellite and measure the time it takes for the signal to return. By doing this repeatedly, they can track a satellite's location and speed.

Global Positioning System (GPS): Satellites in higher orbits like MEO or GEO are tracked using onboard GPS receivers. GPS helps calculate the satellite’s position and relay that data back to Earth.

Optical Tracking: Telescopes and cameras are used to visually observe satellites in higher orbits. This method is particularly useful for tracking objects that do not emit radio signals or need to be monitored for their physical characteristics.

Space Surveillance Networks: Agencies such as the U.S. Space Surveillance Network (SSN) and similar organizations in other countries continuously monitor satellites and space debris. They catalog objects and issue alerts for potential collisions.

What Satellites Track

Satellites are equipped with various sensors, cameras, and instruments to track a wide array of data on Earth, in space, and beyond:

Weather and Climate Data: Satellites such as NOAA’s GOES series monitor weather patterns, hurricanes, and long-term climate changes. They provide crucial data for meteorological services.

Earth Observation: Satellites like Landsat capture high-resolution images of Earth's surface. These images are used for mapping, agricultural planning, disaster response, and environmental monitoring.

Navigation Signals: GPS and other GNSS (Global Navigation Satellite Systems) satellites send signals that are used for navigation by smartphones, vehicles, ships, and airplanes worldwide.

Communication: Satellites facilitate global communication by relaying TV, radio, and internet signals across vast distances.

Space Exploration: Space telescopes like the Hubble Space Telescope track distant galaxies, nebulae, and black holes, helping scientists study the universe.

Military Surveillance: Many satellites are designed for defense purposes, tracking missile launches, military movements, or spying on potential threats.

Number of Satellites in Space

As of 2024, there are approximately 8,000 operational satellites orbiting Earth. The exact number fluctuates as new satellites are launched and old ones are decommissioned. Additionally, space agencies and private companies like SpaceX continue to launch large satellite constellations, such as Starlink, which alone has over 5,000 satellites in orbit for global internet coverage.

The Usefulness of Satellites

Satellites have become indispensable in modern life, serving a wide variety of purposes that impact everyday activities and critical global functions:

Key Functions of Satellites:

Communication: Satellites enable long-distance communication by transmitting data, television, and internet services. Without them, global broadcasting and real-time communication in remote areas would be impossible.

Navigation: Systems like GPS help millions of people navigate in real-time. They are also vital for the functioning of aviation, maritime travel, and even agricultural practices.

Earth Observation: Satellites provide high-resolution imagery of Earth, helping with disaster management, urban planning, agriculture, and environmental monitoring. For instance, they can track deforestation or observe glaciers' melting rates.

Weather Forecasting: Weather satellites provide the data needed for accurate predictions, storm tracking, and climate monitoring. This information is critical for preparing for natural disasters like hurricanes or floods.

Scientific Research and Exploration: Space telescopes and interplanetary satellites gather data on space phenomena, expanding our understanding of the universe. Satellites also conduct scientific experiments in the microgravity of space.

Defense and Security: Satellites are used for military surveillance, early-warning systems, and missile detection, playing a crucial role in national security.

Satellite Highlights in Brief:

Types of orbits: LEO, MEO, GEO, HEO, each serving different purposes.

Tracking methods: Radar, GPS, optical tracking, and space surveillance networks.

Data tracked by satellites: Weather, Earth observation, navigation signals, space exploration, and military surveillance.

Number of active satellites: Approximately 8,000.

Key roles: Communication, navigation, weather forecasting, Earth observation, scientific research, and defense.

In conclusion, satellites are essential tools for global communication, navigation, monitoring Earth's environment, and scientific discovery. As technology advances and the number of satellites continues to grow, their impact on our daily lives will only increase. Whether improving how we predict the weather, navigate through traffic, or explore the universe, satellites will continue to be a critical resource for humanity.

Oh man just when I thought I've seen it all here I come across a bunch of pro-isreal blogs calling the Irish juddenhassen and characterizing them as "drunk football hooligans cosplaying as Palestinian" ... Talk about having a shallow and deliberately dismissive understanding of a country's history. I can't possibly imagine the history or conflict that makes Palestine relatable to the Irish. Also the 'cosplaying' dig is hilarious because you definitely wouldn't respect them more if they were actually Palestinian!

This post is meant to spark discussion, not make people fight or to attack anyone, so please keep that in mind even if you don’t agree with everything I say. I’m not here to evangelize, just to give food for thought.

That being said, I’ve seen a lot of people recently propping up the “lesser of two evils” rhetoric on tumblr, and I am going to be honest: it very clearly comes from a place of fear. I understand, the political climate is frightening right now. But if we continue to approach the situation from a place of panic, prioritizing damage control, we are going to be slowly but surely overwhelmed by the amount of damage we are trying to control. We need to fight for overarching change.

Whether or not that change will come from the electoral system is debatable, but clearly voting is an exigent issue at the moment, so if you believe in that system and put your faith in it, I would urge you to consider voting for someone you don’t think is even a little bit evil. I’m not here to judge you if you’re not ready to do so this election cycle, because yes, I understand that actually getting a third-party candidate in the executive branch in 2024 is a long shot. But I really hope that if you truly want and believe in large-scale change, you have the ability to believe that even just the small change of electing a third party candidate is possible.

If you really agree that by-and-large, Democrat candidates are working against us (albeit less so than republicans), I would encourage you to work to make third-party candidates more viable instead of just accepting that you’re going to end up with a shitty politician either way.

There is plenty of time between now and the election after this one. If you want a non-evil candidate, I would urge you to do what you can to lay the groundwork for one now, so we don’t enter our next election cycle with the overwhelming sense that we have only two options and they both suck ass. The only thing standing between us and a third party win is the allure of habit and the work of organization. I would suggest you research candidates you actually like. Campaign for them, post about them, talk to your friends, family, and neighbors about them.

Every time the election cycle comes around again, we get thousands of new voters who aren’t in the habit of voting for the lesser of two evils, who may be ready for a non-evil candidate. There are many, many people who are dissatisfied with both parties. Electing a third-party candidate is not impossible, just difficult.
