Dynamic dns ( dyndns ) and Global Positionning System :

The global positionning system (GPS) is a system installed on a sattelite able to send you data that indicated your coordinate ( your poistion point ) in the globe.

Actually, when a company needs to know the position on their transport car or other material, it sends a quey by phone to its car. The car or the machine that receives this query will ask for its gps position and sends response to the client ( company ).

Using the phone system as a connexion cost very high for the company. The best idea is to install a server on the car or a machine that could connect via the wimax or sattelite connexion.

The server is running an application specilaized in the determination of the gps position and also has a dynamic dns client ( dyndns client ). This machine has then a connexion point to a wimax internet service provider able to give an internet address ( ip ) to it.

When the internet address changes, the dyndns client sends a query to the dynamic dns server ( dyndns server ) to tell it the new internet address ( ip ) assigned to the machine ( transport car or other). The dynamic dns server will then update the data concerning this machine. The machine of the enterprise is usually iidentified by a name generally an internet sub-domain name attached to the domain name of the company. The most of these sub-domains are dynamic sub-domains names ( they use a dynaic internet address ) and not a fixed internet address.

Therefore, the internet connexions transport by waves like wimax will allow company to use tracking system by using the dynamic dns service and get data and other gps position.
