About the paper

Keywords: VLBI, Digital Backend, Digital Signal Processing

The Deep Space Network (DSN) has replaced the Mark IV Data Acquisition Terminal (DAT) with a digital backend, the DSN VLBI Processor (DVP). The DVP is an in-house Jet Propulsion Laboratory (JPL) development that uses hardware from the Collaboration for Astronomy Signal Processing and Electronics Research (CASPER) for real-time digital signal processing and channelization and streams the data into a Mark 5C recorder in VLBI Data Interchange Format (VDIF). This contribution presents recent enhancements made to the DVP application to improve our support to the international VLBI networks.
