GPS tracker

GPS tracker based on Python engine

This picture shows a breadboard which  contains a complete  GPS tracker on a surface of just 56 mm x 84 mm.  A Quad-band GPRS module and SiRF3 GPS module are also on board,  as well as interfaces for RS232.

The heart of the GPS tracker is a licence free Python interpreter, responsible  for control of GSM module and GPS module. The combined GSM / GPS module are also available for purchase separately. Despite  its small surface area - roughly the size of a matchbox its 64-pin  socket provides a wide array of connectivity options.

This new platform is ideally suited to the expansion of self-sufficient positioning and monitoring systems, which are capable of much more than merely transferring data due to the embedded Python interpreter. Coupled with  environmental sensors, complex pattern recognition applications, for example, can be executed directly on the board. As the geo-coordinates are also transferred wireless, the board is predestined for mobile use.
