Design of the Circuit in a Portable Tracing Instrument Based on GPS Technology

For the problem that the blind, the old man and the children are often lost, a portable positioning instrument had been designed. The instrument is based on the technology of the GPS and GSM/GPRS, circuit design. The instrument is for tracing and tracking of the blind, the old man and the children in real-time. The characteristics of the instrument are quickly and accuracy. The detail position of the missing people could be found by the tracing control center. The tracking and the distribution situation of the blind, the old man and the children could be sent and printed. The low voltage portable positioning instrument has two points in conclusion. The technology is advanced and the function is reliable.
