Multilateralism
In international relations, multilateralism refers to an alliance of multiple countries pursuing a common goal. Multilateralism is based on the principles of inclusivity, equality, and cooperation, and aims to foster a more peaceful, prosperous, and sustainable world. Middle powers play a crucial role in the international system by promoting multilateralism and internationalism. One of the key advantages of multilateralism is that it enables countries to solve problems that transcend national boundaries, such as climate change, terrorism, and pandemics, through shared responsibility and burden-sharing. However, multilateralism is not without its challenges.

Multilateration
Trilateration is the use of distances (or "ranges") for determining the unknown position coordinates of a point of interest, often around Earth ( geopositioning). When more than three distances are involved, it may be called multilateration, for emphasis. The distances or ranges might be ordinary Euclidean distances ( slant ranges) or spherical distances (scaled central angles), as in '' true-range multilateration''; or biased distances ( pseudo-ranges), as in '' pseudo-range multilateration''. Trilateration or multilateration should not be confused with '' triangulation'', which uses angles for positioning; and '' direction finding'', which determines the line of sight direction to a target without determining the radial distance. Terminology Multiple, sometimes overlapping and conflicting terms are employed for similar concepts – e.g., ''multilateration'' without modification has been used for aviation systems employing both true-ranges and pseudo-ranges."Multilatera ...
