Sony provides all necessary components for GPS location estimations with the GXB5205 module.
The only other requirements are voltage and RS232 receiving capability to capture the position outputs.
The module is small and compact to fit into most applications. For the best results, the module should be
placed with the antenna faced towards open sky to capture as much visible satellites as possible.
