And while AmbyGear does all the things you would expect from a kids GPS tracker/GPSwatch, it also has some other neat uses including games and some geocaching support. read more

GPS is a part of most people’s everyday life, whether they know it or not.  But, because these signals are ever present, I doubt most people really ever stop to think about where GPS comes from, or how it got started.

Today, I stumbled across this kind of neat infographic created by GPS tracking company TruVu, and wanted to share it with you. The infographic gives a timeline for the evolution of use of GPS technology. read more

A NASA research team in Pasadena, California has published results of a study of the ionosphere and how its irregularities can effect GPS and other communications in the far North. Working with the University of New Brunswick in Canada, NASA researchers are attempting to predict when and where ionosphere irregularities might occur in the future.

These ionospheric irregularities can greatly distort GPS signals, causing unreliable data. This is mostly a problem in the far North, but it is definitely an issue for pilots flying in the upper latitudes. This research also has plenty of implications for other sciences such as astronomy. read more
