exible navigation system for deep space operations that does not require GPS measurements. The navigation solution is computed using an Unscented Kalman Filter (UKF) that can accept any combination of range, rangerate, planet chord width, landmark and angle measurements using any celestial object. The UKF employs a full nonlinear dynamical model of the

Offshore Technology Conference, 1970
ABSTRACT In certain types of offshore operations, particularly minerals exploration, there is a need for a small fully automatic navigation system which presents position data in such a form that it can be used to steer the vessel without need for further computation or reference to specially prepared charts. Such a

Proceedings of the 9th international conference on Human computer interaction with mobile devices and services, 2007
There has been a rapid growth in navigation aids recently. However, no meaningful personalization exists in these devices. Theories and pilot studies show the importance of individual differences in designing pedestrian navigation assistants. I take a Requirements Engineering (RE) perspective to approach the personalization problem.

Global navigation satellite systems, also known as GNSS, are the set of localization systems that use artificial satellites to determine the position of a receiver in a global (Earth-referenced) system of coordinates. The principle on which GNSS are based is often referred to as triangulation, and it involves estimating the distances from at least ...

Journal of the British Institution of Radio Engineers, 1950
A variety of systems for navigation based on pulsed radio transmission have developed during and since World War II. In this paper a brief review of pulse navigation systems is presented, together with a discussion of the most significant scientific and engineering factors that influence the suitability of such systems for marine navigation.

In many risk domains, such as occupational health and safety, transportation, and food safety, modern risk governance is a success story. Despite these advancements, risk governance still struggles with systemic risk in the context of extreme climate and weather events, associated disasters and emergent risks.

Many animals possess formidable navigation abilities. Conducting research into the exact capabilities and limitations of the mapping and navigation systems used in nature provides two valuable outcomes; knowledge of what animals and insects can achieve using their own sensory and computing equipment, and theories and models of the mechanisms they use ...
