Naudet, C. J.; Sovers, O. J.; Coker, R. F. +2 more

Celestial reference frames determined from measurements of extragalactic radio sources are used in interplanetary navigation, Earth orientation measurements, geodesy, and astrometry. The JPL 1997-3 celestial reference frame is derived from very long baseline interferometric (VLBI) measurements of 291 compact extragalactic radio sources. The observ…
