However, never have I been a champion of the GPS (Global Positioning System), probably because I've had little call to use one. I also don't have a clue as to how it works.
I've learned that it uses signals from satellites in Earth's orbit to identify the latitude, longitude and altitude of the user. All of which seems a bit sophisticated, if not downright superfluous, in making one's way around on any given day.
But what if it's not any given day?
Perhaps I've been too hasty in my assessment.
As we've navigated here in Europe, I can tell you we'd still be trying to find our way out of Dusseldorf had we not had one. In fact, we've grown quite fond of ours. We've named it/her Brunhilda.
But it's not really the GPS I'm fascinated with this day. It's what I've learned:
- It's only as reliable as the coordinates you feed it.
- It's important to get the right country/destination entered, as well as the right city. Many places have the same or similar name.
- So long as you don't second-guess it's directives, you really do end up in the right place.
- It cannot take into account road changes made since it was last updated.
- It never hurts to use common sense in conjunction with it.
- It always know where you are.
I'm not sure Brunhilda cares.
