First EVN fringes to new NASA JPL digital backend

| Description: | In a message to EVNtech, Cristina Garcia Miro, our VLBI friend at the Robledo NASA DSN station, writes: "Coinciding with the 50th Anniversary of NASA's Deep Space Network we are very glad to announce the demonstration of the first fringes between the new DSN VLBI digital backend (DVP) and the European VLBI Network (EVN). The DVP, an in-house JPL development using CASPER/Berkeley technology and the Mark5C Haystack recorder, provides the impressive sensitivity of 19.5 uJy in a 70m-70m DSN baseline (18cm, 1-sigma 150min integration) and is contributing to make the Deep Space Network a world-class Radio Astronomy instrument." The figure shows the fringes (at a wavelength of 18cm) between the DSN Robledo telescope (70m) in Spain and the EVN Effelsberg telescope (100m) in Germany. The data were correlated with the EVN SFXC correlator at JIVE in Dwingeloo, when Cristina visited us last January. For news about the 50th DSN Anniversary check http://www.jpl.nasa.gov/dsn50 . |
