An Interactive Explanation of GPS (2022) (ciechanow.ski)
Global Positioning System is, without a doubt, one of the most useful inventions of the late 20th century. It made it significantly easier for ships, airplanes, cars, and hikers to figure out where they are with high degree of accuracy.

Habitual use of GPS negatively impacts spatial memory (2020) (nature.com)
Global Positioning System (GPS) navigation devices and applications have become ubiquitous over the last decade. However, it is unclear whether using GPS affects our own internal navigation system, or spatial memory, which critically relies on the hippocampus.

NASA uses GPS on the moon for the first time (popsci.com)
On March 2, Firefly Aerospace’s Blue Ghost made history, becoming the first commercial lunar lander to successfully touchdown on the moon’s surface. The groundbreaking lander is wasting no time in getting to work. According to NASA, the joint public-private mission has already successfully demonstrated the ability to use Earth-based GPS signals on the lunar surface, marking a major step ahead of future Artemis missions.

Mapping the Ionosphere with Millions of Phones (nature.com)
The ionosphere is a layer of weakly ionized plasma bathed in Earth’s geomagnetic field extending about 50–1,500 kilometres above Earth1. The ionospheric total electron content varies in response to Earth’s space environment, interfering with Global Satellite Navigation System (GNSS) signals, resulting in one of the largest sources of error for position, navigation and timing services2.

Show HN: I built a Iridium/LTE satellite GPS tracker and took it to the Arctic (github.com/cepa)
One off challenge to build a custom GPS tracker that sends data to cloud over LTE and Iridium networks. Tested successfully on the expedition yacht S/Y Southern Star while crossing Barents Sea from Norway to Svalbard in the Arctics. Built with RockBLOCK 9603N(Iridium), SIMCOM7600G (LTE/GSM) and STM32 microcontroller (ARM,FreeRTOS).
