How Accurate if Phone GPS

Recommended Posts

It's a common question an one that can lead to a range of answers, so here is our take on the problem.

Military equipment aside, ultimately all GPS receivers use the same chip set and satellites so phones can have single digit meter accuracy, and much of it comes down to signal strength, so this depends on what you are comparing your phone with. If it is a standard GPS receiver then there will be no difference in accuracy and if you read on then you will find that your phone may be more accurate.

 

Other GPS systems can use additional satellite signals and signal from beacons to improve accuracy above what you might get from a phone.

 

However, the latest phones also use WiFi and mobile phone signal to improve accuracy, so in urban areas mobile phones can be more accurate than standard GPS receivers.

 

In rural areas, it all comes down to signal strength, and if you have a device with a stronger receiver it will out perform a mobile phone but you will have to pay around 5 times the price.

I recently ditched my tom tom and now use satnav on my iphone. It seems just as reliable so far...oh and the app was free!

 

Using nav free on the iPad, it's like sat nav on steroids.

 

The tracking for the iPhone is pretty accurate, it nearly tells you which pocket you left it in
