The system which is calculated whether by his is somewhere on the earth making use of the satellite accurately. At one of the US military military technology, 30 bases making use of the radio wave which the satellite which is arranged dispatches in the orbit around the earth, from several cm to calculate in several dozen m errors it is possible the latitude longitude altitude and the like of the receiver.

The GPS satellite which the Department of Defense manages (are called the “NAVSTER satellite” formally) on six orbital planes of high-level approximately 20,000 km respectively four or more and total 24 or more to be arranged, the earth the circumference is done at approximately 12 hour period. Approximately, in order to enter life at 7 year half, like every year launching the new satellite, we have thrown to the track, 30 approximately satellites are used usual in general. The GPS satellite has built in the atomic clock of the high performance, the data which includes time with radio wave of the 1.2/1.5GHz band is transmitted to the ground.

The QUALCOMM corporation developed, position information acquisition technology for the cdmaOne/cdma2000 terminal. GPS (all the terrestrial determination systems) with the technology which is applied, it transmits the data which is acquired from the satellite to base station that way, it does actual position decision depending upon base station. Information in order from base station to search the satellite in the terminal concerning the reception from the GPS satellite is transmitted, the time when it is necessary for the start of reception from the satellite has been shortened substantially. At the interior where the radio wave from GPS does not reach, determination is done making use of the radio wave from base station. Precision of information of position reaches the 5m - 10m level which is equal to usual GPS. Position information offer service “coconut Secom” which Secom starts in 2001 April, is the service which utilizes gpsOne for the first time. Presently even with position information retrieval function “eznavigation” of the au portable telephone it is used.

The portable telephone which presently can inform position GPS (all the terrestrial determination systems) by. If it is in the range where radio wave of the GPS satellite can be received, latitude of present location and it is possible to know longitude and altitude.

Map service and the navigation which utilize the information of position of the GPS k tie (the guidepost) service, regional information offer service and the service etc where the parent can grasp the address of the child are offered. The type which builds in GPS function increases yearly, spread is advancing. When being in accident, also the application that is examined it transmits the information of position when informing to urgent information service and fire fighting and the police who transmit the information of position automatically automatically.

All the terrestrial determination systems which the Department of Defense manages (GPS) the satellite which is used. As for GPS satellite with alias, NAVSTER (NAVigation Satellite Timing And Ranging) satellite formal name.

Of four or more and the satellite total 24 or more is arranged respectively on six orbital planes of high-level approximately 20,000 km, the circumference does the earth at approximately 12 hour period. Approximately, in order to enter life at 7 year half, like every year launching the new satellite, we have thrown to the track, 30 approximately satellites have done the circumference in general. We build in the atomic clock of the high performance, we transmit the data which includes time with radio wave of the 1.2/1.5GHz band to the ground. Receiving the radio wave from the plural GPS satellites, presently to measure position by calculating the distance of each one, it is possible the GPS receiver. At the place where three satellites are visible at the place where four satellites are visible to calculate altitude in addition to this it is possible latitude and longitude.
