  The DSN Transient Observatory (DTO) is a signal processing facility that can
monitor up to four DSN downlink bands for astronomically interesting signals.
The monitoring is done commensally with reception of deep space mission
telemetry. The initial signal processing is done with two CASPER ROACH1 boards,
each handling one or two baseband signals. Each ROACH1 has a 10~GBe interface
with a GPU-equipped Debian Linux workstation for additional processing. The
initial science programs include monitoring Mars for electrostatic discharges,
radio spectral lines, searches for fast radio bursts and pulsars and SETI. The
facility will be available to the scientific community through a peer review
process.
