We have designed and built a testbed demonstrating an angle sensor that measures the relative angular position between two free-flying spacecraft when used in conjunction with a distance-metrology system. In flight, one spacecraft would carry an LED beacon while the other would carry the sensor system. Our fixed, staring testbed sensor demonstrated a 10 degree capture range with 0.1 arcsec resolution over the inner 1 arcmin of field, and an update rate of over 100 Hz. The testbed showed this performance for simulated spacecraft separations of 100 to 1000 meters.
