azimuth deflection
1deflection change — noun Change in azimuth setting applying to all guns in a battery when the target moves, or when a shift is made from one target to another. Deflection change does not include the deflection difference which allows for the difference in positions… …
2Vertical deflection — The vertical deflection (deflection of the plumb line, astro geodetic deflection) at a point on the earth is a measure of how far the direction of the local gravity field has been shifted by local anomalies such as nearby mountains. (Here gravity …
3Circular error probable — In the military science of ballistics, circular error probable (CEP) (also circular error probability or circle of equal probability[1]) is an intuitive measure of a weapon system s precision. It is defined as the radius of a circle, centered… …
4Corrected firing data — was a term used in the U.S. Coast Artillery to refer to firing data (range and azimuth to the target) that had been corrected[1] for various non standard conditions. This could include corrections to range and corrections to azimuth or deflection …
5Radar display — Modern radar systems typically use some sort of raster scan display to produce a map like image. In the past, notably during the early days of radar development, such displays were difficult to produce for a number of reasons. Several different… …
6Indirect fire — means aiming and firing a projectile in a high trajectory without relying on a direct line of sight between the gun and its target, as in the case of direct fire. Aiming is performed by calculating azimuth and elevation angles, and may include… …
7Coast Artillery fire control system — A conceptual diagram of the flow of fire control data in the Coast Artillery (in 1940). The set forward point of the target was generated by using the plotting board (1). This position was then corrected for factors affecting range and azimuth… …
8geoid — geoidal, adj. /jee oyd/, n. 1. an imaginary surface that coincides with mean sea level in the ocean and its extension through the continents. 2. the geometric figure formed by this surface, an ellipsoid flattened at the poles. [1880 85; < Gk… …

10Geodesy — (pronEng|dʒiːˈɒdɪsi [OED] ), also called geodetics, a branch of earth sciences, is the scientific discipline that deals with the measurement and representation of the Earth, including its gravitational field, in a three dimensional time varying… …
