Abstract
There has been a steep growth, throughout the World, in civilian UAV applications.
UAVs offer cost effective alternatives for many applications, as they enable objectives
be carried out without the risk to pilots. In terms of crop surveillance, they offer a cheap
alternative to satellite and manned aerial imagery. These current techniques are limited
due to cloud cover, and poor image capture resolution. By flying a UAV at low
altitudes, these limitations may be greatly reduced. With the recent financial
commitment from the Queensland State Government, to the funding of a UAV research
and development facility, the future of UAV technology and its potential market is
being recognized. Current UAV navigation and guidance packages on the market are
prohibitively expensive. This paper describes the design and implementation of a cheap
navigation and user interface for the specific purpose of carrying out surveillance over a
pre-determined flight path in a UAV. The system has been designed assuming a suitable
automatic flight control system is available, for receipt of the guidance outputs.
By using a HC12 microprocessor, GPS, compass and transceivers, in conjunction with a
navigation algorithm, guidance of the UAV is made possible by producing heading
error and altitude to feed to the automatic flight control system of a UAV. A digital
camera and electronic trigger unit are used for taking surveillance photos over the pre-
determined path. A user interfa
