Technical Data - SimCom SIM548C HD V1.01 Hardware Design

SIM548C Hardware Design
GPS CORE
The on-board processor is running an algorithm that calculates the position, velocity and time.
This calculation is called navigation solution. Once the navigation solution is calculated, it can be
transformed into the desired coordinate system, e.g. Latitude/Altitude.
DATA OUT
The data of the navigation solution are available at the serial RS-232 interface.
