Before handheld SatNav became to cheap, this was the only way to get a handheld GPS mapping system that was portable. Nowadays, they still have a use where you wish to track your route, store travel details (location, speed, date, time, altitude, etc). In fancy speak, used for "location based services". If you plan to buy one, the receivers with "SiRF III" chipset inside are reputed to be the overall better devices. After interfacing to the Mac, decoding the serial data stream is simply a case of taking the text string, splitting it on commas to get an array of data, and then interpret it: http://www.gpsinformation.org/dale/nmea.htm Perhaps your next version of "SayitMailit" will have a "Where Am I?" feature, relaying the current GPS location...! > From: Rich Love <carnationsoftware@...> > Reply-To: <futurebasic@...> > Date: Fri, 28 Aug 2009 15:41:59 -0500 > To: <futurebasic@...> > Subject: Re: [FB] How to obtain Longitude > > That's amazing.
