Phone GPS are triangulated off of cell signal. So depending on your signal and proximity to towers will determine accuracy. My iPhone was almost spot on with my Garmin in the Detroit River. However, when I got out into Lake Erie, it was off by a few MPH..

iPhones have GPS built in. They do not rely on cell towers for location services, although their satellite locking hardware is likely not as sophisticated as a full marine GPS, you should be able to get very accurate numbers from it nearly anywhere in the world. in fact if you are near cell towers as mentioned. the iPhone may be more accurate than a marine GPS since it has multiple modes of triangulation to determine location.

I´m not claiming to be un expert on GPS devises but from my own experiences with Garmin marine GPS (not the latest models )and by compairing them with technology like the samsung Galaxy S3 4G i find the difference first to be the that the galaxy find it´s satelites in no time ,like when you press the map button on the S3 . It´s there instantly. The Garmin 182C marine could take more then a few minutes before it´s ready.(The phones and the marine GPS always shows the same readings at the end by a tenth) There was a big test when they compared sport/running watches like Garmin forerunners and the Polar series with a modern iphone app.They all got their ass whipped by the phones. I´m a runner to and today like often my GPS sport watch(Garmin 110 ) took close to 5 minutes to be ready.My Galaxy is there directly. I´m not a sales man for Samsung just compairing different ways of measuring "landspeeds" accurate. Would really appreciate un expert on the subjekt to comment. I´m guessing here but the thing seems to be how many satellits the device are shooting at or being able to use. ??
