GpsOne——混合定位系统展望

Overlook of GpsOne--a New Hybrid Position Location System

无线运营商提供的小区无线定位服务有两种工作方式:一种是基于网络的定位方式,另一种是基于手机的定位方式。GpsOne是一种综合GPS和CDMA系统定位技术来提高定位位置服务质量的混合定位技术。CDMA和GPS紧密结合,使得GpsOne成为一种低成本、高效率的定位服务。最后介绍了Gpsone原理及其优点,并展望了GpsOne今后在移动定位服务中的广泛应用前景。

The cellular location problem can be solved by using either network - based method or handset - based methods. Gp-sOne is a. hybrid position location technology that combines measurements trom GPS and forward arid reverse links of a CDMA system to improve position service availability. Tight integration between the CDMA and GPS parts of the wireless device will result in a low - cost implementation. The principles and benefits of integrating GPS in a CDM A system using the gpsOne approach are described.
