Product Description
This document specifies the electrical, mechanical and behavioral characteristics of
Samsung multimode GPS engine module. Samsung multimode GPS engine module is
illustrated in figure 1 below. In a cell phone application, Samsung multimode GPS engine
module works under a protocol stack executing on the cell baseband. Samsung multimode
GPS engine module accepts GPS *istance information from the cell baseband and
performs all signal processing necessary to acquire and determine satellite code phase
information (also referred to as pseudo-range), time tags and the code phase information
can return. Samsung multimode GPS engine module presents a simple UART serial
interface to the cell baseband processor.
A communications protocol is implemented from which the cell baseband processor issues
commands to the GPS baseband and obtains responses.
This protocol includes the download of GPS baseband software from internal flash
memory, SGEM can be operated Conventional Autonomous mode and Assisted
Autonomous mode when aiding information be supported from the server
