Alas...What Has Led To The Disappearance Of My GPS iPhone?

by Roger Tavares
There are a ton of different features offered on the new Apple iPhone device, including calls, SMS, voicemail, photos, and ringtones. Notably, one of the least talked about and yet most technologically advanced and resourceful of all is the iPhone GPS feature.

What it is

Basically GPS satellites circle the Earth twice a day in a very precise orbit, during this time they transmit signal information back to the Earth. Anyone owning a GPS receiver - such as the iPhone GPS for instance - takes this given information and uses triangulation to properly calculate the user's exact location.

The iPhone GPS feature is great for a number of different reasons, but namely, if you ever lose your iPhone or stolen, then you can easily find it by using the GPS technology.

The GPS receivers that are used today are incredibly accurate, and the receivers are quick to lock onto satellites when first turned on and more importantly are able to maintain strong locks, even in the event of dense foliage or urban settings where there are lots of buildings and other blockages.

There are a few reasons that there would be a problem with your iPhone GPS receiver or any other GPS receiver for that matter. These include: ionosphere and troposphere delays, signal multipath, receiver clock errors, orbital errors, number of satellites visible, satellite geometry and shading, and intentional degradation of the satellite signal itself.

Any one of these can result in causing a delay or other problem with your iPhone GPS receiver however these are problems that can usually be fixed quite easily.

Other Features

The GPS is not the only notable feature of the iPhone, in fact far from it. There are actually tons of other features that you are offered with the iPhone, one of particular importance being the SMS feature. SMS or text messaging as it is more commonly known as, is very popular among the general public, but is especially great on the iPhone.

One of the particular aspects on the iPhone that makes it just so great is the fact that all your text message conversations are shown to you in bubble formations on the screen when you go to write the next message, so you are shown the last things that were written between you and the sender.

This makes it easy to keep track of your various different text messaging conversations, which is especially when you are constantly messaging with a ton of different people at the same time.
