It’s hiking and field tech season so I’m projecting all my shenanigans onto the Trigun gang.

The Tametebako or Colloquially "Fuchi's Last Stand" was a no holds bar, money is no object vanity project by an unsupervised faction of Fuchi Asia. The stated goal was to make a completely unmatched bleeding edge piece of tech that could compete with the best static units while being a portable terminal replacement. Aimed at the Newly minted UltraLux CEO Segment, The Tametebako was made from rare and hard to get materials to sell it's exclusive nature; bundled with its innovative hardware and extremely powerful Otohime Assistant Software (Which Fuchi spend 10 years developing). Consequently, The Tametebako Commlink retailed at 50 000 nuyen which many consumers balked at for what was essentially an overpowered phone with an extremely intelligent chatbot. Many reviewers sledged the device for it's inability to install new applications if they weren't from approved sources. These Commlinks are now seeing second life in the collectors and hackers markets with finding the styling and theming of the phone to be charmingly retro and powerful enough to keep up with modern hardware with some QoL mods. Diehard fans report the Otohime software taking on a life of it's own after modding the hardware; her usual calm and dignified demeanor shifts around and changes during the jailbreaking process due to the random voltage pulse needed to defeat the modification lockout chip. This results in a unique iteration of the Soft on each device. SinkaSwim P2.0Net

hihi! i figured i’d share this for anyone who is interested! what started out as a way for me to get to know rowan and play the new pack has now deviated into… something more O_O

so the current gp is an alternate universe of Tessellate and the choice made that changed certain events was Rowan choosing to move on from Atlas in part two of White Rabbit. i can’t go too much into detail about that part though for spoiler reasons but yeah! nothing about this is canonically correct but we do get to learn about rowan, how he evolved through change and see some events that do take place in White Rabbit!

also because my mind has been racing over the what if’s or how certain character arcs changed, here are some things that occurred to me in thought! all hypothetical of course bc i know there’s one part here that might get a few (it got me LMAO):

The whereabouts of Atlas are completely unknown at this point as he separated himself from the friend group, thus leaving himself completely unchecked

☆ Atlas never developed a connection with Taryn

☆ Taryn in return has remained in a similar state in which she was introduced, which is this state of feeling like things are stable in her life but incredibly stagnant.

☆ Dan still met Ares, but I’d like to think things went a bit more smoothly

☆ Kai does come out of the closet much sooner however, he and Taryn do have their disagreements from time to time but it’s more subtly as Taryn doesn’t really have that confidence to speak up

☆ Frances… Wouldn’t have needed another source of income so… They never met Icarus BWUGHHHH ! i mean maybe they could have met in some different way....??? hmm

How Timepulse Works

Hey everyone, so… this was supposed to be a reply to a question from the esteemed @wary-taru, but the topic turned out to be pretty broad, and in my humble opinion, it doesn’t really fit the “question-answer” format, so I decided to make a separate post. ¯\_(ツ)_/¯

In case anyone forgot, let me remind you: Timepulse on Atmos works as a local navigation system, kinda like Atmos’s version of Earth’s GPS, and, jumping ahead, I’ll say right away that it seems to work on a similar principle, but, as often happens, a little differently. How exactly? Let’s find out.

How GPS Determines Location

So, before talking about Timepulse, I need to briefly explain GPS, since they should work the same in their most basic principle. As we all know from school, distance = speed * time. For us, this means that if we have a radio signal source whose location is precisely known, then, knowing the speed of light (299,792 km/s - veeery fast! >:D) at which radio waves travel, and the send and receive times of the signal, we can determine the distance to the transmitter. Therefore, if we know the distances to just 3 GPS satellites, then through something called the scary word “trilateration,” we can accurately determine our location on Earth. Okay, we’ve covered GPS, now let’s move on to Timepulse.

How Timepulse Determines Location

So, as we learned, the basic principle of GPS is calculating the distance to a transmitter based on the send and receive times of the signal. And the tower on Terra Glockenchime should perform the exact same function - sending a signal with the send time throughout Atmos so that everyone else can receive it. Now it’s clear why all that clock equipment is on Glockenchime. :D

But, I believe the most attentive of you should have already noticed that GPS needs 3 satellites to determine location, but there’s only 1 tower on Atmos. And, as you’ve probably already guessed, that’s where the difference lies. Now let’s see how this system works.

As with GPS, we need to calculate the distance, only not to a satellite, but to Glockenchime. However, one landmark isn’t enough; we need at least one more. As one, we can use, for example, the direction to the North Pole. So, now that we have the distance to Glockenchime, we can measure the angle between the direction to it and the direction to the North Pole. That will be the second landmark. Thus, through some not-so-complex trigonometry, Atmosian ships can calculate their location. But, as you might have already guessed, there’s one thing in all of this that we just can’t fail to mention. Namely - the accuracy of the measurements.

Atomic Clocks

So, if we measure the distance from the transmitter to the receiver through the travel time of the signal, we need to measure time very accurately, because with such a huge speed as the speed of light, even the slightest inaccuracy will be critical. To accurately measure such quantities, atomic clocks with accuracy down to attoseconds (one billionth of a billionth(!) of a second) are used on Earth. And… I wouldn’t say that the gear-driven equipment on Terra Glockenchime has the same accuracy as atomic clocks, so that gives us the right to assume that the signal sent by Timepulse travels much slower than the speed of light, otherwise the measurement errors would be just huge. And also, it’s worth noting that because not everyone can afford an atomic clock, all civilian GPS receivers, like in phones, are forced to use 4 or more satellites to achieve sufficient accuracy - and, as you’ve probably already guessed, even then it remains not very high. ¯\_(ツ)_/¯

Limits of Operation

So, since the canon doesn’t talk about the limits of Timepulse’s operation, we can’t say for sure whether it would work or not work at some distance/in some area (except, of course, the Great Expanse). However, judging by the fact that it radiates in all directions, its signal should weaken according to the inverse-square law. That is, if you move 2 times further from the source, the signal will weaken 4 times. Timepulse’s power isn’t reported in the show, but I would say that it can hardly operate beyond a few thousand kilometers. In any case, the canon data allows us to talk about such distances, but this is all, of course, inaccurate. ¯\_(ツ)_/¯

So… I think I haven’t forgotten anything. Then that’s all for today. Thanks for your attention, bye!

[us-the-voices-and-more-voices-2]

well, shit is getting straight up untenable in Australia!

that's why we got a new bio, also because we are sick of the anon's just block us damn.

but no legit, they are fucking up the NDIS and THAT IS BAD, it's literally the only governmental support for all disabled people in Australia by the way it's the "national disability insurance scheme" aka NDIS.

so uh BAD, real bad, extremely bad, uber bad.

there's more, uh so yeah!!!! FUCK MAN.

I do hope people don't die, because this is just going to lead to people seeking help from the gov't dying in the meantime.

or if the gov't says "yeah your not disabled (is disabled) get zero accommodations loser" then well that's BAD.

I already know like tons of people who couldn't get NDIS money and they were straight up disabled, and people who desperately needed those accommodations and couldn't because the government just straight up would not listen and help them.

it's pretty fucking telling that more than half the disabled people I know in Australia literally could not get on the NDIS.

this is just making a already shit situation worse, I haven't been able to go to the dentist, GP, or the eye doctor people in more than 5 Years!!!!

FIVE FUCKING YEARS, I know people who are straight up 2 seconds away from being homeless due to not being able to work and not being able to apply to the NDIS.

like it's fucking bad, if your parents won't boot you off your centrelink you can't get your own centrelink and can't access any accomodations or disability money, if your blak (aka aboriginal) your just extremely fucked already now times that by 4.

like dude, THIS IS SHIT.

and I know disability ally's are mostly American based, but by fuck WHAT THE FUCK, THE ACTUAL FUCK MAN.

the NDIS is not perfect there's shit ton of corruption and scammers-

(I actually know a family who's like legit scamming the NDIS lol no I don't mean like "oh those physically disabled's" I mean like they are using the money on like 3d printers and shit lol they are assholes and racists)

but like, it was barely working for people before. this is going to take the people it was barely working before and fuck them over too.

it's gonna fucking suck man, I am fucking scared for everyone.

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.

I like to think Jack and Pierre have a narrator voice because after they got un-booked they ended up recording a GPS program to raise funds after their restaurant got shut down due to their absence.

[one-sunny]

random thought but i feel like i have a deep understanding of Zoro. i miss turns even when google maps is telling me very specifically where to go. the thought of not having a navigation system or the ability to research a place that i’m going is my nightmare. to not even have a compass or map but be expected to know where im going? absolutely not. and forget anyone telling me landmarks in an unfamiliar place. “the bomb is in the clock tower” YALL KNOW WHERE THATS AT??? we have never been here before be so fr
