The answere is yes I took postion reading from 300 miles from Jamaca, jamaca, grand caymen islands, and cozumel mexico.. The ships speed was 22.8 mph into the wind and 23.6 with the wind. I had some old guy explain to me that gps will not work in gulf of mexico because the sats are all over the USA. I had 11 to 12 sats every time I turned my garmin 650. If any wants to know what long and lat I had I'll tell them cause I am lazy to put it in..
Apparently
The old guy does not know what the "G" in GPS stands for....what a maroon.

G is for
"G" is for "Garmin" - yeah?

The Old Guy was right

The old guy was correct, most GPSr (including the Nuvi) will not work "in" the Gulf of Mexico, "on" the Gulf they all do; I know, while fishing in the Gulf I dropped one overboard and after retrieving it no longer worked.

Lost Satellite Reception
Plus its hard to get decent satellite reception "in" the Gulf. As flaco said, its much better "on" the Gulf.
I plan to live forever. So far, so good.
GPS constellation
The person telling you that GPS won't work while onboard a ship in the Gulf of Mexico was not well informed.
The GPS Constellation consists of 32 satellites that are in orbit about the Earth. Each satellite is in an orbit that has an inclination of approximately 55 degrees. That is, the angle between the equator and the orbit is 55 degrees. Think of a big globe with a hula hoop around it. The angle between the hula hoop and the equator on the globe is 55 degrees.
What this means in English is that the satellites will be directly overhead anywhere on the planet from 55 degrees south through 55 degrees north latitude.
Thus, it will fly directly overhead if you are as far north as the bottom of Hudson Bay or as far south as southern tip of South America. If you are anywhere between these points, the constellation will be flying directly overhead and your GPS should work perfectly.
As you go farther north than 55N or farther south than 55S, then the satellites will be lower and lower on the horizon and the geometry will make it harder and harder for your GPS to get an accurate calculation of your position.
Thus, as you saw for yourself, your GPS worked perfectly on the ship in the gulf.
More accurate GPS soon?
I had heard that more GPS satellites will be launched in the future to provide much higher accuracy. Such technology was speculated to be used in GPS guided cars. Any truth to this?

To what end ??
Thus, as you saw for yourself, your GPS worked perfectly on the ship in the gulf.
I guess that depends on your definition of "perfectly".
What GPS brand has maps of the Gulf available ???
Magellan Maestro 4250// MIO C310X
Gulf Maps for mapquest
I hope they make maps of the Gulf and that Garmin works with it as I have used my GPSr to help navigate my way on a sail boat race.
If you can read this thank a teacher! If it's in English thank a Vet!
Yeppers! It would be great if it worked in the gulf! LOL!
I just spent several weeks on and in the gulf!
No problem working on the gulf, but when it came to diving (in the gulf), hmmmmm had to use the good ole' compass. Wow, I forgot how spoiled I was with my gps.
Happy Trails!
