However, since the VLBI technique measures the time differences between the arrival of radio waves at separate antennas, it can also be used "in reverse" to perform earth rotation studies, map movements of tectonic plates very precisely (within millimetres), and perform other types of geodesy.
Namun, karena teknik VLBI mengukur perbedaan waktu antara kedatangan gelombang radio pada antena yang terpisah, juga dapat digunakan "secara terbalik" untuk melakukan studi rotasi bumi, gerakan peta lempeng tektonik sangat tepat (dalam milimeter), dan melakukan lainnya jenis geodesi.
