“…The signal flow and on-instrument processing are described by Buu et al (2011). Briefly, a radio signal is received at a DSN antenna and downconverted from S band (2.2-2.3 GHz), X band (8.2-8.6 GHz), or Ka band (31.8-32.3 GHz) to an intermediate frequency (IF).…”

“…Two time resolutions were implemented, 100 μs and 1 ms. In the 1 ms time resolution mode, RRAT TRAP does real-time de-dispersion/detection for 98 positive dispersion measure (DM) trials and 98 negative (non-physical) trials to search up to a maximum |DM| of 2000 cm −3 pc (Buu et al 2011). At this time resolution the prototype's data buffering and disk writes keep up with real time.…”

“…In post-processing we performed incoherent dispersion correction using the Crab's nominal DM (≈56.8 cm −3 pc) to produce a time series of dispersion-corrected data. Buu et al (2011) show examples of dynamic spectra of strong individual pulses and time series of raw and de-dispersed pulses using our receiver (see also the Appendix for series of intensity along the dispersion track for our two brightest pulses). We estimated the rms noise away from any bright pulses in each buffer to normalize the de-dispersed data series as (de-dispersed intensity − mean intensity)/rms noise versus time.…”

“…As a firmware change to the standard spacecraft tracking receiver, we built a prototype dispersion-correcting and transientdetecting receiver that processes information in the currently unexamined DSN bandwidth (Buu et al 2011). This was a proof-of-concept instrument to demonstrate the feasibility of DSN piggyback astronomical observations without requiring any additional hardware.…”

Recent discoveries of transient radio events have renewed interest in time-variable astrophysical phenomena. Many radio transient events are rare, requiring long observing times for reliable statistical study. The National Aeronautics and Space Administration/Jet Propulsion Laboratory's Deep Space Network (DSN) tracks spacecraft nearly continuously with 13 large-aperture, low system temperature radio antennas. During normal spacecraft operations, the DSN processes only a small fraction of the pre-detection bandwidth available from these antennas; any information in the remaining bandwidth, e.g., from an astronomical source in the same antenna beam as the spacecraft, is currently ignored. As a firmware modification to the standard DSN tracking receiver, we built a prototype receiver that could be used for astronomical transient surveys. Here, we demonstrate the receiver's utility through observations of bright pulses from the Crab pulsar and describe attributes of potential transient survey observations piggybacking on operational DSN tracks.

“…Rotating radio transients. With DSA 3 it will also be possible to search for transient events in radio waves just as with NASA deep space antennas (Buu et al 2011). The so-called RRATs (Rotating RAdio Transients) have been recently discovered (McLoughlin et al 2006, Lorimer et al 2007) as sources of very intense pulses that may be of extragalactic origin.…”

The European Space Agency (ESA) will inaugurate its third Deep Space Antenna (DSA 3) by the end of 2012. DSA 3 will be located in Argentina near the city of Malargüe in the Mendoza province. While the instrument will be primarily dedicated to communications with interplanetary missions, the characteristics of its antenna and receivers will also enable standalone leading scientific contributions, with a high scientific-technological return. We outline here scientific proposals for a radio astronomical use of DSA 3.Resumen. La Agencia Espacial Europea (ESA) inaugurará, a finales de 2012, la tercera antena de espacio profundo (DSA 3), en suelo argentino (Malargüe, Mendoza). El instrumento se dedicará principalmente a comunicaciones con misiones interplanetarias. Dadas las características de la antena y receptores, con la DSA 3 se podrán realizar contribuciones científicas de punta, con un alto retorno científico-tecnológico. Aquí se delinean propuestas científicas para su uso radioastronómico.
