China completes core of Beidou global satellite navigation system
By Lurker,
Two Chinese Beidou navigation satellites successfully launched Monday on top of a Long March 3B rocket, completing the core of China’s independent positioning and timing network ahead of the start of global service next year.
The 184-foot-tall (56-meter) Long March 3B rocket lifted off from the Xichang space base in southwestern China’s Sichuan province at 0722 GMT (2:22 a.m. EST; 3:22 p.m. Beijing time) Monday, according to statements issued by the country’s top state-owned aero
Automated Remote Sensing of Underground Features
By Lurker,
While many advancements have been made this last decade in automated classification of above surface features using remote sensing data, progress for detecting underground features has lagged in this area. Technologies for detecting features, including ground penetrating radar, electrical resistivity, and magnetometry exist, but methods for feature extraction and identification mostly depend on the experience of instrument user.
One problem has been creating approaches that can deal with c
Open Repository for Geospatial Training Data Released
By Lurker,
Radiant Earth has launched Radiant MLHub, a cloud-based open library for training geospatial data used by machine learning algorithms. In launching the repository, Radiant Earth noted that while there is an abundance of satellite imagery, there is a lack of training data and tools to train machine learning algorithms. Radiant MLHub is a federated site for the discovery and access of high-quality Earth observation (EO) training datasets and machine learning models. Individuals and organization

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
