Abstract
Increased DSN receiving capability far beyond that now available for Voyager is achievable through a mix of increased antenna aperture and increased frequency of operation. In this note we consider a sequence of options: (1) adding mid-sized antennas for arraying with the existing network at X-band; (2) converting to Ka-band and adding array elements; (3) augmenting the DSN with an orbiting Ka-band station, and (4) augmenting the DSN with an optical receiving capability, either on the ground or in space, Costs of these options are compared as means of achieving significantly increased receiving capability. The envelope of lowest costs projects a possible path for moving Jrom X-band to Ka-band and thence to optical frequencies, and potentially for moving from ground-based to space-based apertures, The move to Ka-band is clearly of value now, with development of optical communications technology a good investment for the Suture.
