GPS Global Positioning System is the English acronym, meaning global positioning system. Is a global, all-weather, all-time, high-precision navigation and positioning and timing of delivery systems. 24 satellites in six inclination of the orbit of 55 degrees plane with a high degree of 20,182 km, cycle nearly 12 hours. Satellite launched two one-way L-band frequency range signals from different satellites using CDMA distinction. It is a dual-use system that will offer two classes of service. In order to improve navigation accuracy, availability and integrity of the various countries to develop differential system, fully meet the needs of the general civilian. Scrambling at the same time SA has gradually been cancelled, and civilian accuracy has been greatly increased. The working principle of GPS is not complicated, to put it in simple terms, is the use of satellite launches receive signals, coupled with the well-known geometrical and physical to some of the basic tenets into position.

Development of the current MP4 step in the direction of vehicle users is the vehicle users know more concerned about is the way the current MP4 Lane has been a lot of products with GPS, car users in the hope that the awareness of road can also look at the same time read the news and match, with GPS will also be one of the MP4 future development trend.

3. Key words - thin and light

Packed, it is all digital products as a development direction, who did not want to carry the bulky portable products difficult, of course, MP4 players will also take this step. Currently on the market in high-end MP4 mostly use the hard disk storage medium, since it is bound to cause hard drive MP4 increase the volume of natural weight will increase.

If North Korea would like to develop thin and light, first of all, uses flash memory as a storage medium, today's flash memory development speed is fast, Samsung mp4 player also recently announced a 32 GB capacity flash memory cards, as long as the weight of MP4 use flash memory and the thickness down naturally.
