Wireless
Introduction
The RF
(Radio Frequency module) provides reliable wireless
communication for the transfer of data.
Most
RF- module used in our day based on frequency modulation.
In FM, the carrier amplitude remains constant, while the
carrier frequency is changed by modulating signal (base band
signal).
FM
is used to transmit digital data. When the modulating signal
is binary, a binary 1 input produces one carrier frequency,
and a binary 0 input produces another carrier frequency.
In
our project , we will use
dual band FM wireless Transceivers
to transmit and receive the GPS
message contained
in air plane.
Main
Objectives
- Taking
the GPS message from GPS receiver contained in the plane.
- Transmitting
this message using RXQ1 RF module in transmission mode.
- Receiving
this message using RF RX-module located at the base
station.
- Entering
the message to the computer via 9-pin PC serial port.
The
GPS message is continuously transmitted to base station to
indicate the position of the air plane . (i.e.
The GPS acts as a position sensor.)
