GPS receiver

Is there any advantage of getting a GPS unit that has more channels? I've seen some that support up to 32.

 

Doubt it, simply because you're never going to have more than about 12 or 15 GPS satellites in the sky, wherever you are on Earth and whatever time and day it is.

 

USA is launching some more GPS satellites and these are superior to the older ones but i think these are intended to be replacements and it's not going to bump up substantially the number of satellites in orbit.

 

Oh yes - thought you might like to know that GPS receivers work out of a plane window too (small window though they are). I got my max. recorded speed this way on my Garmin etrex Vista - 556mph !!!

Try not to let a stewardess see you though - they tend to get a bit nervous about it and think it's a missile homing device or mobile phone or something.

One saw me using mine by the window in about 2002 and asked me what it was. When i told her she said that the pilot already had one of those and that she didn't think we needed two on-board ! I switched it off....

But you would have been able to tell her if instead of going to Benedorm you'd already had a mid air pilot exchange and were now going to visit the upper floors of some modern architecture. She should have viewed it as a potential early warning system, and thanked you as such. :)
