  We have designed and tested an in-plane echelle spectrograph configured to
investigate precision radial velocities from ground-based near-infrared
observations. The spectrograph operates across the spectral range of 0.9-1.7 mm
at a spectral resolution of R = 50,000, and uses a liquid nitrogen-cooled
HAWAII 1K detector. Repeated measurements of the Earth's rotation via
integrated Sunlight with two different instrument arrangements in the near
infrared Y band have produced radial velocities with ~10 m/s RMS over a period
of several hours. The most recent instrument configuration has achieved an
unbinned RMS of 7 m/s and suggests that infrared radial velocity precisions may
be able to approach those achieved at optical wavelengths.
