Low power (2mW) lasers mounted on a small satellite in a highly eccentric orbit can provide a bright and spectrally well-defined reference source for calibration of ground-based adaptive optic systems. Because the reference is spectrally well-defined it can be efficiently filtered in broad-band imaging applications and yet can provide a very bright reference source for wavefront detectors when imaging faint sources. Dependent on the size of the atmospheric isoplanatic patch, the satellite reference may be useful for calibrating observations of selected objects for periods in excess of 1 hr, leading to limiting magnitudes for detection of up to +30. The area of sky for which the reference is valid is restricted (order 1 sq deg of sky per telescope per year). The reference is valid for phasing aperture synthesis telescope arrays of kilometric scale. Orbital maneuvers for target selection and to increase the sky coverage will be considered.
