lookangle
Lookangle, in the context of navigation, astronomy, and telecommunications, is the angle between an observer’s local horizon and the line of sight to a target. It is typically described by two components: azimuth and elevation. The azimuth is the compass direction to the target projected on the horizontal plane, usually measured clockwise from true north. The elevation is the angle above the local horizon, ranging from 0 degrees at the horizon to 90 degrees at the zenith.
In practice, look angles are used to point sensors and antennas toward a target such as a
Calculation typically requires the observer’s position (latitude, longitude, altitude) and the target’s position (which may be
Applications of lookangle include satellite tracking, radio link budgeting, astronomical observing, and other line-of-sight targeting tasks.
