gnss-sdr VS three.js

You realise you can write software yourself to interpret the signals from GPS satellites? Here's an open-source implementation.

Something I always enjoy pointing out is that GPS signals can be decoded by anybody, the source code is available here. Needless to say, there are references and calculations based on satellites all over it.

If you're interested in running some code, there's [1] which is fairly active, but as I recall is Linux only. There is also [2] which is a Matlab (or Octave) GNSS receiver implementation; quite well documented and informative. It's meant to be a companion to the author's book [3], which itself I found quite concise and approachable.

They like to pretend it is using towers or balloons or something else, none of them have ever coherently answered it with a viable way this could result in the GPS we can use from the device in our pocket. It also casually expands the circle of people involved in this conspiracy by thousands, to include all developers at Apple and other phone manufacturers that write/maintain the GPS components of their OS as well as contributors to open source projects like GNSS-SDR, an open-source software-defined GNSS receiver.

People also have to write the software to compute your location from these broadcasts, this means basically every company that has produced GPS receivers would have to be in on it. But there's an open source one, surprisingly nobody has raised an issue as to why it contains all this weird code that doesn't make sense if it's not coming from a satellite.

Regarding the optimization of the effect, I found an issue on the three.js GitHub repository: https://github.com/mrdoob/three.js/issues/14104 The alpha channel issue seems to be a difficult problem, which has been present since 2018. At the end of the discussion, a solution proposed by a contributor is not to modify the UnrealBloomPass but to blend the source texture and target texture in the shader.

Here's how we used Three.js to place and find affirmations in the sky.

Three.js is dedicated to generating 3D visuals, offering a powerful suite of features and tools. It is built atop WebGL and optimizes GPU usage for rapid rendering, ensuring smooth performance across devices, including those with limited resources. Three.js's versatility allows for the creation of a vast spectrum of 3D graphics and animations, ranging from simple shapes to intricate models.

Most of frontend libraries are made with Vanilla JS. An example of library that you might frequently use is "Chart.js". But React is not compatible with Chart.js so here it comes "React-chartjs-2" A wrapper library to work with Chart.js in React ecosystem. Oh you want to use "three.js" for some cool 3D? you will need "React-three/fiber". In my case, I need to implement "telegram-web-app", not so fast, I have to create my own wrapper to be able to use it.

For one of my 100-Day Challenges, I chose to dive into Three.js, a JavaScript 3D library. It's easy to start learning, and it becomes difficult to master with the inclusion of shaders.

Nonetheless, it offers nearly infinite possibilities. You can code and create anything, from a mobile app with React Native to a desktop application with Electron.js. Furthermore, JavaScript provides excellent frameworks and libraries that can be applied in various approaches, such as React, Three, Vue, Meteor, and Astro.
