Although commercial solutions for tracking goods via GPS and mobile networks already exist, we wanted to create a prototype with this very function.
Unlike other implementations, reducing costs was not the number one priority. The software was made to be resilient to unusual circumstances, the execution flow is controlled by interrupts and timers with no blocking functions, data is buffered in a memory chip and the entire project is Open Source.
It is highly customizable - it accepts 22 different commands via sms and the tracking information can be sent to any web server. All the protocols used - including the packet dissection is documented in the manual.
