For many years, unmanned aerial vehicles (UAVs) have been used for security and defence, search and rescue and for the surveying and mapping of remote areas. As the demand for their application soars, so too will the need for increasingly complex control systems, navigation equipment and communication technologies to keep them in the air and on course.
In 2006, the Canadian Forces Station (CFS) Alert -- the northernmost permanently inhabited settlement in the world -- suffered a serious fuel spill when a fuel line break caused 22,000 litres of diesel to leak into the surrounding soil. With approaching freezing temperatures and weather that would prove both harsh and unforgiving, an immediate and innovative clean-up solution was needed.
