    Writing A GPS Receiver From Scratch

    Lurker
    By Lurker,
    GPS is an incredible piece of modern technology. Not only does it allow for locating objects precisely anywhere on the planet, but it also enables the turn-by-turn directions we take for granted these days — all without needing anything more than a radio receiver and some software to decode the signals constantly being sent down from space. [Chris] took that last bit bit as somewhat of a challenge and set off to write a software-defined GPS receiver from the ground up. As GPS started as a m

    Rocket Lab launches Japanese SAR satellite

    By Lurker,
    Rocket Lab launched a synthetic aperture radar (SAR) imaging satellite for a Japanese company March 14, the first of eight such missions Rocket Lab has under contract with that customer. The Electron rocket lifted off from Pad B of Rocket Lab’s Launch Complex 1 at Mahia Peninsula, New Zealand, at 8 p.m. Eastern. The payload, the QPS-SAR-9 satellite, separated from the kick stage nearly an hour later after being placed into a planned orbit of 575 kilometers at an inclination of 42 degrees.

    Maxar launches GPS-alternative navigation system for drones

    Lurker
    By Lurker,
    Maxar Intelligence developed a visual-based navigation technology that enables aerial drones to operate without relying on GPS, the company announced March 25. The software, called Raptor, provides a terrain-based positioning system for drones in GPS-denied environments by leveraging detailed 3D models created from Maxar’s satellite imagery. Instead of using satellite signals, a drone equipped with Raptor compares its real-time camera feed with a pre-existing 3D terrain model to determine i

    DEM2STREAM ArcGIS Desktop tool

    yousef2233
    By yousef2233,
    Hi everyone This straightforward tool generates a stream order network from elevation data (DEM). The only input required is a DEM. As an open-source tool, it is accessible and easy to use. If you encounter any issues, feel free to contact me at [email protected].  Tested with ArcGIS Desktop 10.8.1😊 Let me know if you'd like further refinements Download Link   To create a stream network and determine its order in ArcGIS starting with a Digital Elevation

    • GPS is an incredible piece of modern technology. Not only does it allow for locating objects precisely anywhere on the planet, but it also enables the turn-by-turn directions we take for granted these days — all without needing anything more than a radio receiver and some software to decode the signals constantly being sent down from space. [Chris] took that last bit bit as somewhat of a challenge and set off to write a software-defined GPS receiver from the ground up. As GPS started as a military technology, the level of precision needed for things like turn-by-turn navigation wasn’t always available to civilians. The “coarse” positioning is only capable of accuracy within a few hundred meters, so this legacy capability is the first thing that [Chris] tackles here. It is pretty fast, though, with the system able to resolve a location in 24 seconds from cold start and then displaying its information in a browser window. Everything in this build is done in Python as well, meaning that it’s a great starting point for investigating how GPS works and for building other projects from there. The other thing that makes this project accessible is that the only other hardware needed besides a computer that runs Python is an RTL-SDR dongle. These inexpensive TV dongles ushered in a software-defined radio revolution about a decade ago when it was found that they could receive a wide array of radio signals beyond just TV. source: Hackaday and  GitHub - chrisdoble/gps-receiver
