UK trials updated 1950s naval tech, avoids GPS jamming risk
Author: Tiffany Shoman
It’s always nice to see an old tech stage a return and this time it’s occurring around the coastlines of Europe, with 9 low-frequency radio transmitters replacementing for GPS’ satellite-based system. eLoran’s radiowave-based system is stronger than satellite signals and less jammable, based upon the Loran system that was formerly used for shipping navigation by both the British and United States navy over 50 years back. But despite its age, the tech has actually shown amazing hardy against undesirable interference. In trials performed by the General Lighthouse Authorities of UK and Ireland, a 1.5 W radio jammer had the ability to knock out GPS indicates over a range of 30 kilometers. Nevertheless, to do the exact same to the Loran system, you ‘d require a 40ft tower– and around 25kW of juice to power it.
The basics behind Loran and GPS are mainly the same, with gadgets measuring the time it takes for a signal to take a trip in between a transmitter and your receiver. Loran needs three songs, with places then calculated through “trilateration”. More signal input consequently equals a more safe and secure position read-out, with the elderly base system providing initial place precision to around 100 meters. Nevertheless, the updated eLoran signal (currently only being broadcast on the eastern coast of the UK, around Dover) will narrow that to the closest 10 meters. The GPS back-up will be slowly rolled out across the whole British shoreline.

Poodle Skirts!: Batman Characters Reimagined In 1950′s
Author: Heather Brown
Note: I feel like I’m near death today guys (just in time for a holiday weekend!), so bear with me. At one point this morning I even saw the light at the end of the tunnel. It…looked like flames.
This is a series of sketches from Italian artist Denis Medri of Batman characters reimagined as rockabilly ones from the 1950′s. Let’s all go to the sock hop and cut a rug or whatever! Then we can swing by the soda fountain for a root beer float. No? You just want to make out in the back of my dad’s Chevy at Makeout Point? WELL NO THANKS. My parents raised me right so I’m saving myself for marriage somebody more attractive.
Hit the jump for a bunch more characters, most of which capture the 50′s better than this one but how am I not gonna put Batman on the cover of a Batman related post? He’d batarang me in the nuts!
