(astronomy) Initialism of very-long-baseline interferometry.
For Planet-wide geodetic surveys, previously impossible, we can still mention Satellite Laser Ranging (SLR) and Lunar Laser Ranging (LLR) and Very Long Baseline Interferometry (VLBI) techniques. Source: Internet
While negligible for most human activities, terrestrial tides' semi-diurnal amplitude can reach about convert at the equator—convert due to the sun—which is important in GPS calibration and VLBI measurements. Source: Internet
Geodetic measurements main Project manager Stephen Merkowitz talks about his work with NASA's Space Geodesy Project, including a brief overview of the four fundamental techniques of space geodesy: GPS, VLBI, SLR, and DORIS. Source: Internet
Because they are so distant, they are apparently stationary to our current technology, yet their positions can be measured with the utmost accuracy by Very Long Baseline Interferometry (VLBI). Source: Internet
