The Rhino Posisiton

The Rhino Position



Is given by GPS, not any particular rhinos personal view....:-)

GPS Makes Mountain Higher

GPS Makes Mountain Higher



That headline of mine is bullshit of course. :-) GPS measurements are more precise than photogrammetry though, and new measurement of this Welsh mountain manages to 'move' it over the 1000 meter threshold. I would not call it a super mountain though...:-)

Improved GPS

Relativistic GPS



Since everything is moving relative to each other (The Earth rotates around it's only varying axis, around the Sun and in the galaxy etc) it is hard to define a pure inertial system - or coordinate system for positioning if you like. Hence we call upon Einstein! :-)

Tracking You Down - Indoors!

Galileo (GPS) Tracks You Down Indoors




No more escapes!

Butterfly Navigation

Butterflies with 'GPS'



Clocks are important - and complicated - in Global Navigation Satellite Systems (GNSS) or GPS as most people know it as. I assume butterflies also have a rather sophisticated chronometer...:-)

A Green Sun

A Green Sun






Messing with our Local Green Space and Green Earth. At least the GPS satellites suffers from solar outburst like huge flares similar to the one we see above.

Galileo - Europe's Global Navigation Satellite System


Galileo is grand. I'm not thinking of Galileo Galilei, he is grand too of course, but on the European Global Navigation Satellite System named in his honor, Galileo. GNSS is one of the pillars of space geodetic techniques.

It is not that I dislike green, but rather that I LOVE blue and I get so sick and tired of everything called green. Why not blue? After all a clean and healthy OCEAN is environmental even more than the green you find on the continents covering merely 30 % of this planet's surface anyways. I'm just saying....before I give you GreenDrive. :-) Call it BlueDrive and I'll buy several for my car!



GreenDrive advises the driver on the most economical driving style to use, when to accelerate, when to break, and when to keep the speed. This is done on mobile phones and personal navigation devices.

Trucks and GPS

Tracing Trucks for Environment




With Global Navigation Satellite System GNSS (or GPS if you like) and some other techno stuff.

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.

Galileo and GLONASS

Space Navigation



This Global Navigation Satellite System is composed by both Galileo satelllites and GPS satellites. 'GPS', or rather GNSS, receivers and the augmentation system in Norway can receive signals from both GPS and GLONASS now. In the future I believe all nations will be able to receive signals from all the global systems on their receivers.

GPS Dog

GLONASS on Putin's Dog

"Russian Prime Minister Vladimir Putin watches his dog Koni that wears a GPS device on its collar in the Novo-Ogaryovo residence outside Moscow."

Koni (Connie) live

Global Navigation Satellite System - GNSS, is the internationally agreed general name, not GPS. GLONASS (Ru) is a GNSS, GPS (US) is a GNSS, Galileo (EUR) is a GNSS, Compass/Beidou (Cn) is a GNSS.

So actually I'd say GNSS on Putin's dog. It is definitely not GPS, though. :-)

Satellite Navigation

Solar Storms Knock-Out GPS



Credit: NASA/ESA/SOHO

A radiation storm is recorded by the SOHO spacecraft Friday, Sept. 9. The white speckles are caused by protons striking the craft's digital camera: The camera has a device that blocks out the Sun itself.




Solar storms can, have done and will knock out satellites such as GPS. Having multiple Global Navigation Satellite Systems will improve the services, but nevertheless, it is a real problem.

I remember particularly the event in September 2005 (see image above) when several GPS satellites were non-functional and the GPS system suffered from lack of signals.

On September 5, 2005, the C2 coronagraph observed a bulbous coronal mass ejection heading out from behind the left side of the Sun. This is just about where old sunspot region 798 would be. When viewing this active region previously, it was producing several substantial solar storms. It was probably the source of several large solar storms that occurred on the far side of the Sun. And just as scientists suspected it might perform, the same region, while still just at the Sun's left edge, erupted two days later with an X17 flare (almost off the scale) and an associated CME. If the estimate is correct, that would make it the fifth largest flare ever recorded.

So far the Sun has been quiet; before the storm?






If you prefer red and blue poetic cats to the Sun, have a look here! :-)

Evil Jamming

Global Navigation Satellite Systems



Vulnerable to [evil] jamming.

We who work on the Global Navigation Satellite Systems (GNSS) know how vulnerable our society is to both sabotage and solar activities knocking down the systems such as GPS (USA), GLONASS (Russia) and Galileo (future Europe). That is why we have been very surprised that alternative systems like the military Loran C were terminated by some countries. It looks like things are being reconsidered...:-)

GPS Applications

New Thermometer!



GPS beyond your wildest dreams.

The atmosphere alters the path of GPS signals that is being sent through it, hence we get information about the medium. We already have GPS applications within atmospheric research, the next generation of applications will be even more sophisticated - like a new thermometer. :-)
