(Goldstone 34-m)
NASA DSN Radio Astronomy18-26 GHz Receiver Concept
NASA DSN Radio Astronomy
Data recorders (Standard DSN equipment) MkV VLBI (500 MHz BW, post real-time
processing) VLBI Science Receivers ( 4x16 MHz BW, near real-
time software PFB, FFT, AC) Autocorrelators (Spaceborne)
Canberra (400 MHz, 4096 ch) Madrid (500 MHz, 1024 ch) Goldstone (500 MHz, 1024 ch)

NASA DSN Radio AstronomyFuture Capability
Search for extragalactic water masers: two polarization beamswitching (four IFs) with 8192 ch over 400 MHz
Search for RRATs and isolated bursts (400 MHz BW real-time de-dispersion and capture)
Giant nanosecond pulses between 18 and 26 GHz, full Stokes (de-dispersion and capture)
Monitor Mars electrostatic microdischarges
