This is the source code for GSM - GPS based Vehicle Tracking System done using PIC microcontroller and CCS C Compiler
GPS编程 This is schematic and Gerber files of PCB that is used for GPS tracking device with GSM link. Scheme
This is schematic and Gerber files of PCB that is used for GPS tracking device with GSM link. Scheme has many valuable schematic features, like protected digital and analog I/Os, power part adapted for car power supply, etc.
Can be used as a reference design for anyone who wants to make own GPS GS ...

Software-defined radios (SDRs) have been around for more than a decade. The
first complete Global Positioning System (GPS) implementation was described
by Dennis Akos in 1997. Since then several research groups have presented their
contributions.We therefore find it timely to publish an up-to-date t ...
