Relative positions of two or more points can be determined using very-long-baseline interferometry.

One radio astronomy application in this band is for Very-long-baseline interferometry.

This may be detected either by using pulse timing techniques or by very-long-baseline interferometry.

Perform Radio Astronomy (both single-dish and very-long-baseline interferometry) observations.

Very-long-baseline interferometry (VLBI) is a type of astronomical interferometry used in radio astronomy.

This technique, known as very-long-baseline interferometry (VLBI), can determine with great accuracy the distance between two points on the Earth's surface by using radio telescopes.

Such motion should be detectable either from timing measurements, or from relative astrometry with the Parkes-Tidbinbilla Interferometer or with Parkes-Hobart very-long-baseline interferometry.
