The application of CDMA location technology in first aid system

Data package,including personal information and current position,is crucial factor to strive for succor time in long-distance first aid system.An design based on CDMA2000 1X network was advanced for long-distance first aid after describing several kinds of positioning technologies.This design has the feature of GpsOne position technology,a hybrid position location technology that combines measurements form GPS and forward and reverse links of a CDMA system.The paper detailed the software and hardware design at last,the feasibility of the design was also discussed.
