GPS(Global Positioning System)
The PMB 2520 Hammerhead is a IC sulution for GPS that producted by the Infineon Technologies. It allows the usage of assistance data by surpporting A-GPS standards.
The Hammerhead consists of the following modules:
The Hammerhead integrates 3 serial interfaces:
The UART in the Hammerhead is a full-duplex UART interface. It is fixed in 8N1(8 data bits, no parity, 1 stop bit) mode. On the GTA01, the host processor connect with the Hammerhead through the UART.
