Improved Global Navigation Satellite System

Galileo improves global navigation



Today with the Global Navigation Satellite System (GNSS) system GPS




Today with the augmentation system EGNOS on top of GPS




Future GPS and Galileo

Clearly Galileo will improve our navigation systems, not only in Europe but globally. As with todays GNSS, the American GPS, the north is not covered well enough. Norway is contributing to improve the systems so that we get the necessary accuracy in the vulnerable arctic as well.

This image of Mars reminds me of modern metallic sculptures. HiRise never disappoints me. I always find space art when I visit. :-)

Games

Guitar Hero Rules



This household has the whole package of Guitar Hero games. Right now we use Playstation 3. Fantastic electronic devices, I must say. :-) I didn't reflect on the aesthetics of having a huge drum set in the living room until I read a comic on the topic somewhere...anyways, the gear is visible in the landscape of our livingroom and the multitude of guitars also demands some space. Whatever.

It is so much FUN! :-)

Say It With Science

Accurate Maps



Cartographer: graphjam.com

I not only thumb up (SU tool) this glorious map, I give it an outstandingly good review: This must be the best map of the US ever made. And I have spent hours at the Library of Congress's Geography and Maps Division and seen true art of cartography and I work for a national mapping agency! This map represent the sharpest observation of American culture. It is accurate, and that is what maps need to be in order to be a useful navigation tool.

Why do I glorify this particular map? Because I can. And because of all the people with a total lack of sense of humor thumbing this post down. I GREEN it!

Moreover, I know the map is correct because I know at least two awesome Californians: Yopp and XineAnn. Plus a whole bunch of other people...:-)

Oh, come on now! SUers, thumb this map UP, up, up! :-)








Thank you Tutto.
