Last month, a drone was tested to do a pipeline inspection over 14.5 miles of pipeline. During the test flight, the drone used Echodyne’s remarkably small radars to detect and avoid “non-cooperating” aircraft on its own. The manufacturer claims that Autonomy is the future. Radar is the absolutely essential sensor you need in the array. But Echodyne says it needs the Federal Aviation Administration to finish writing regulations for unmanned aircraft before its business will really take off.
