GPS Based Aircraft Collision Avoidance
Name Andrew Leung Supervisor Dr Vaughan
Clarkson
A portable, low cost communication system for use
in general aviation to prevent collisions and aid
in navigation
The Concept This system would consist of a device
to be carried in an aircraft that would transmit
and receive position and velocity information to
and from matching devices carried in other
aircraft in its vicinity. The device would derive
an exact three-dimensional location using a GPS
unit and periodically transmit this information
over the RF datalink. When the system is not
transmitting, the device would monitor
transmissions from other units, perform
calculations on the received positions and
velocity, and determine whether there is a risk
or collision. The information will be displayed
on a display unit and would provide an
appropriate warning to the pilot.
The Microcontroller The microcontroller selected
is the Texas Instruments MSP430F149. It is
mounted with two serial port for communication
between the display unit and the GPS receiver.
GPS Receiver The Motorola GT Plus Oncore GPS
Receiver provides position, velocity, time, and
satellite tracking status information via serial
port. It has an 8 parallel channel design capable
of tracking 8 satellites simultaneously. A timing
receiver which uses a precise one pulse per
second (1PPS) timing output.
Display Unit The display unit is a Compaq iPAQ H
series installed with a Familiar Linux
distribution. It displays the location of nearby
known aircraft and present Traffic and Resolution
Advisories as required.
