closest point of approach en
1closest point of approach — noun An estimated point in which the distance between two objects, of which at least one is in motion, will reach its minimum value; abbreviated CPA. The estimate is used to evaluate the risk of a collision of e.g. two ships …
2Closest pair of points problem — Closest pair of points shown in red The closest pair of points problem or closest pair problem is a problem of computational geometry: given n points in metric space, find a pair of points with the smallest distance between them. Its two… …
3Point on plane closest to origin — In Euclidean 3 space we will find the point on an arbitrary plane that is closest to the origin using the method of Lagrange multipliers. First, let us start with an arbitrary plane, ax + by + cz = d. The distance, L, from the origin to a point… …
4Distance of closest approach of ellipses and ellipsoids — The distance of closest approach of two objects is the distance between their centers when they are externally tangent. The objects may be geometric shapes or physical particles with well defined boundaries. The distance of closest approach is… …
5Floating point — In computing, floating point describes a method of representing real numbers in a way that can support a wide range of values. Numbers are, in general, represented approximately to a fixed number of significant digits and scaled using an exponent …

8Automatic Radar Plotting Aid — A maritime radar with Automatic Radar Plotting Aid (ARPA) capability can create tracks using radar contacts. The system can calculate the tracked object s course, speed and closest point of approach (CPA), thereby knowing if there is a danger of… …
9Mini Automatic Radar Plotting Aid — (or MARPA) is a radar feature for target tracking and collision avoidance. Targets must be manually selected, but are then tracked automatically, including range, bearing, target speed, target direction (course), CPA (closest point of approach),… …
