The use of unmanned aerial systems (UAVs) for civilian search-and-rescue operations or disaster management is not new. This article explores the concept, development, and results of a project to develop an unmanned system on board an aircraft. The drone was equipped with a thermal/optical camera and a multi-sensor navigation system that uses EGNOS, the European augmentation system. And it succeeded at demonstrating its utility for a particular application: finding people lost in remote and rugged outdoor environments.

MEMS vs. FOGs

Improvements in microelectromechanical systems (MEMS) used for positioning and navigation have made them a candidate technology for precise positioning applications that were previously dominated by fiberoptic gyroscopes (FOGs). This article describes development of a MEMS-based integrated navigation system (GNSS/inertial) and a similar FOG-based system and compares their performance in field trials, both aided by GNSS and on their own.

This second part of a discussion of peer-to-peer cooperative positioning revisits the topic of sharing critical information across clusters of GNSS users. This article focuses on users within GNSS-challenged environments equipped with both a GNSS receiver and a terrestrial ranging system and shows that sharing information can enhance the availability of position solutions to the network as a whole.
