iLocater is a next-generation precision radial velocity spectrograph under development for the Large Binocular Telescope (LBT). The instrument has three major subsystems which are currently undergoing simultaneous development: a single-mode fiber fed high-resolution (R~150,000-240,000) NIR echelle spectrograph, an adaptive optics fed fiber-injection system, and a fabry-perot etalon based wavelength calibration unit. We present a design, performance and status update for iLocater and its individual subsystems as the instrument moves from design to fabrication.
