Circuit Description

Figure 5-1 Diagram of GPS Circuit

GPS positioning information can be acquired via the programmed GPS key on the front panel. The
GPS function is realized via REB-1315LPx module, which integrates GPS baseband processor
circuits.
The GPS signal (1.57542GHz), received via the GPS active antenna (with a built-in LNA), goes to the
GPS module for processing, and then enters U302 via the UART port. Meanwhile, U302 sends control
command to the GPS module and forwards processed GPS information to the LCD.
