Laser Retro Reflector Array

A Laser Retro Reflector Array (LRRA) will be used for POD validation of KOMP-SAT-5. The KOMPSAT-5 LRRA developed by GFZ (GeoForschungsZentrum) is shown in Fig. 6. The KOMPSAT-5 LRRA has four cube corner prisms mounted in a compact frame. A bracket will be used to compensate the tilt angle of the spacecraft and ensuring a better field of view. Figure 7 shows the configuration of the LRRA.
