Triangulation
Measurement of the distance of a planet or nearby star by sighting its apparent position against background stars from two or more separate locations. (see Parallax)

Triangulation
In trigonometry and geometry, triangulation is the process of determining the location of a point by measuring angles to it from known points at either end of a fixed baseline, rather than measuring distances to the point directly...
triangulation Method of determining distance based on the principles of geometry. A distant object is sighted from two well- separated locations.
To use triangulation to measure distances, a surveyor must be familiar with trigonometry, the mathematics of geometrical angles. However, even if we know no trigonometry at all, we can still solve the problem by graphical means, as shown in Figure 1.

Simultaneous observations of the azimuth of the discharge are made at all stations and the location of the storm is determined by triangulation.
Compared with window glass, obsidian is rich in iron and magnesium; tiny ( obstacle avoidance (NASA Thesaurus) The use of sensors utilizing laser triangulation as means of preventing collisions, ...
Astronomical distance measurement began with a knowledge of the Earth's diameter, which provided a base for triangulation. Within the inner solar system, some distances can now be better determined through the timing of radar reflections.
In the case of the Sun it was done in the same manner that we determine distances here on the Earth: by the method of triangulation.
In the 1670s, Cassini begun work on a project to create a topographic map of France, using Reiner Gemma Frisius's technique of triangulation.
Correlation and analysis of the recorded wavefronts yields a very precise triangulation from which the angular position may be determined by direct comparison to the position of a quasar whose RA and DEC are well known.
The directional accuracy of a single detector was (and remains) poor; the best positions for bursts use time-of-flight "triangulation" from multiple detections including interplanetary spacecraft (for the stronger bursts, ...
The primary objective of the experiment was the accurate determination of the directions to the sources of such bursts through a technique of triangulation as a member of a widely spaced array of similar instruments (ISEE-3, -11 & 12, Helios-2).
Distances are of fundamental importance in astrophysics, and the only direct method of measuring them is by triangulation.
This shift can be used to determine distances (through "triangulation"). Stellar parallax occurs as the Earth orbits the Sun and our line of sight to a nearby star varies.
Hubble used triangulation on nearby Cepheids, and correlated the Cepheid's period to their absolute brightness. Then by measuring the period and brightness of Cepheids in nebulae, he established their distance by their brightness.

This effect, called parallax, can be used to calculate the distance to the star with simple geometry; a similar method of triangulation is used by surveyors to measure distances on Earth.
