SubPos – Wifi enabled Positioning System

Description When the world's lifeforms are forced into subterranean dwellings due to nuclear fallout, evolution into lizard people or warming of the Earth, we will require a simple method for determining our position underground. In our current age, we are still working out the intricacies associated with determining our location in areas where GPS cannot reach. SubPos provides a solution to this problem, w ...

2018 Will Mark A Milestone in GPS Technology with 30-centimeter Accuracy

You’re in a crowded street with many high buildings around you and you find your car position on Google maps is wrong. That’s usual, right? This is caused from (fake/distorted) GPS signals reflected from the high buildings around you which make your GPS receiver do some wrong calculations. So be careful don’t always listen to what GPS assistant says! Even with no wrong calculations, the current GPS accuracy ...

THIS GPS SPEEDOMETER HANGS OFF YOUR HANDLEBARS

If you can ride a bike with no handlebars, no handlebars, no handlebars, you can do just about anything. You can take apart a remote control, and you can almost put it back together. You can listen in on a two meter repeater and you can build a GPS module speedometer. That’s what [Jeremy Cook] did with just a few parts, a little 3D design, and some handy zip ties to hold it onto the handlebars, the handleba ...
