Not to mention it's not a GSP device as spammie gave in the subject line. :) I like these sites. http://www.gpsreview.net/ http://www.gilsson.com/gps_reviews.htm Bought my last GPS from http://4x4books.com/, not much on reviews but good on price. -- DougW |

Re: Popular GSP Devices
The links that you provided are mostly reviews and comparisons!
Not much information otherwise. On Thu, 27 Dec 2007 09:16:40 -0600, "DougW" <I.only.read.usenet@invalid.address> wrote: >J.

> Good day, > Please explain what is incorrect with the below links information. Start with "A GPS receiver calculates the exact position of a person by using the signal strength from each satellite to narrow down the position." Signal strength, as long as it is sufficient to allow the signal to be deciphered, has nothing to do with position determination. GPS works on timing, not signal strength. "To make the readings even more accurate, a GPS receiver uses signals from a stationary GPS receiver station. A stationary GPS receiver station already knows its precise location, so a GPS receiver can utilize the signals from a receiver station to correct any errors. This technique of calculating coordinates is known as differential GPS and almost all commercial GPS receivers available in the US come equipped with differential GPS." While not incorrect, this is misleading. If you buy a consumer GPS it will have support for DGPS but you'll also need to be within range of a transmitting station and have a DGPS receiver compatible with that service, which is a separate device that plugs into the GPS. There is no mention of WAAS, which most commercially available GPS units support and which provides accuracy close to that of DGPS with a single satellite providing the corrections. The only manufacturer mentioned is Garmin--no mention of Magellan, Trimble, or any of the other manufacturers. The wikipedia article contains a great deal more information. > > On Thu, 27 Dec 2007 07:06:49 -0500, "J.
