Solving the polarization problem in ALMA-VLBI observations [Elektronisk resurs]

, 2014
The Atacama Large mm-submm Array (ALMA) is, by far, the most sensitive mm/submm telescope in the World. The ALMA Phasing Project (APP) will allow us to phase-up all the ALMA antennas and use them as one single VLBI station.

Combining VLBI and GPS for inter-continental frequency transfer [Elektronisk resurs]

, 2015
For decades the Global Positioning System (GPS) has been the only space geodetic technique routinely used for inter-continental frequency transfer applications. In the past VLB) has also been considered for this purpose and the method's capabilities were

VLBI monitoring of the structure of the ICRF sources - The Bordeaux VLBI Image Database

The extragalactic radio sources that make up the International Celestial Reference Frame (ICRF) can exhibit extended and time-variable brightness distributions (or structures) on VLBI scales, setting limits on the accuracy of the astrometric source positions determined from the VLBI measurements. For this reason, regular VLBI observations are organized
