Integer Ambiguity Resolution

The process of determining the correct whole number of carrier wavelengths in GNSS positioning to achieve centimeter-level accuracy.

intensity

A measure of the strength or magnitude of a physical quantity, such as light, sound, or earthquake waves, per unit area or volume.

intersection survey

A surveying method that determines the position of a point by measuring angles from two or more known reference points.

iono free

Iono free refers to the ionosphere-free linear combination used in GNSS surveying to eliminate first-order ionospheric effects on signal propagation.
