Next Technology

On the 23rd October 2001, the world was introduced to a technological phenomenon that would change the way people listen to music forever. The release of the iPod was much anticipated and it did not let anyone down.

The first iPod released had a capacity of 5GB which was enough for the user to have 1000 songs on. Second and third generation iPod were subsequently released in 2002 and 2003 respectively with slight improvements to make the product more user friendly.

By the time the fourth, fifth and sixth generation models had been released, the iPod had become very sophisticated with memory of up to 160GB available for users to upload their favourite songs as well as films and episodes of their favourite programmes. The iPod has well and truly become the market leader in MP3 players.

As well as the classic styles, Apple also released other versions of the iPod including the Mini, which was a smaller, lightweight version of the classic with less memory. The Nano, slim and sleek and ideal for those constantly on the go, and the iPod shuffle which was a screen-less version that was designed for those exercising as it was very small.

On the 5th September, Apple once again raised the bar. The iPod Touch was released which had Wi-Fi capabilities and a Multi-touch interface. Internet access was perceived to be the only thing missing from the product so Apple corrected this and made it available providing a Safari browser.

Another reason the Apple iPod gets good reviews is for the accessories it provides. One of the most successful has been the iPod Hi-Fi; many users flocked to the shops to buy the product that was a docking station for the iPod that allowed the user to play the songs on a high quality sound system.

Added to this, the release of the iPhone and iPhone 3G means that Apple are set to have a good Christmas with many of their products being at the top of Christmas lists. With a range of iPod accessories , finding the right iPod for christmas is easy. For all the best deals on an Apple iPod and more shop online and compare prices.

The Global Positioning System (GPS) was originally developed by the US Military who launched satellites (the first satellite was launched in 1978) into orbit. The system consists of a network of between 24 and 32 satellites orbiting the earth at about 7000 mph, in a precise manner, two times every day.

In the early days only the military could track the signals but in the 1980’s it was opened up to the general public.

Before we get into the specifics it is important to realize that the use of the satellite network is free, there is no subscription required.

The other benefit is the system is essentially unaffected by weather and it is accurate anywhere in the world. Some might recall the Loran system which was popular with boaters before GPS became popular.

Loran was capable of providing a very accurate position but only in limited areas where the transmission of signals was sufficient and provided the weather was not adverse.

GPS transmission satellites orbit the earth in a very precise and constant manner. As they orbit 12,000 miles above, they transmit radio signals 24 hours a day, every day. The receivers we use simply receive the transmitted signals and compare the time the signal was transmitted against the time it was received. Knowing the signals travel at a fixed rate of speed makes it easy to calculate how far the satellite and the receiver are from each other.

If this process were done with only one satellite the result would not be useful for us since it would only indicate a possible arc of a position. To provide accuracy the receiver has to receive signals from a minimum of 3 satellites.

In actual use, the receivers typically track the signals from many more satellites.
In order to provide data like speed, direction, distance traveled, etc. the receiver repeats the position calculation on a continual basis and thus updates the position and other data. The signal transmitted includes the satellites ID, the satellites position at any given time and the date and time.

Accuracy of the receivers has improved with technology advances to an average of about 15 meters. In real practice it is common to see accuracy within a meter or two, at least at times.

When GPS was opened up for public use the signal was intentionally degraded by the Government which was referred to as Selective Availability (SA). SA has been discontinued so civilians now enjoy full accuracy of the system.

Technology referred to as Wide Area Augmentation System (WAAS) available with some receivers improves accuracy to about 5 meters. Receivers equipped with Differential technology apply corrections to the data based on other known references.

The end result is accuracy and functionality of gps receivers to the point we all can rely upon. As a result we now see and enjoy GPS watches, auto and boat GPS navigation systems, GPS cell phones.
