The Third Cambridge Catalog of Radio Sources
The 3C Catalog is the result of observations with the Cambridge four-element interferometer at a frequency of 159MHz, and contains 471 sources between declinations -22 and 71 degrees, with a flux density larger than 8Jy.

Next Space VLBI Mission "VSOP-2" by HALCA
The VSOP mission with HALCA achieved a number of remarkable results. The follow-on mission, VSOP-2 by ASTRO-G satellite, was approved as ISAS's 25th scientific satellite project. With significant improvements in performance, the VSOP-2 will challenge uncharted areas in astronomy.

The Radio Optical Reference Frame Optical Image Database (OID)
Presented here are preliminary results of an ongoing program to obtain precise optical positions of the RORF sources. The radio frame, defined by the positions of selected extragalactic radio sources, can now be established to an accuracy of better than one milliarcsecond.
