Imagery of revealed a circular excavation, probably for the rail framework to support a second international Telecommunications Satellite Organization (INTELSAT) antenna, at Pyongyang Satellite Communications Station Oryu Ri 6 nautical miles west of Pyongyang (Figure 1). The circular excavation was in a cleared square area 200 meters from the INTELSAT support area and 400 meters from an already-operational INTELSAT antenna (Figure 2). No evidence of the circular excavation was observed on imagery of This report contains one location map and one annotated photograph. (S/WN) 2. According to open-source collateral,' the present, operational, 27-meter antenna was intended for use with the Indian Ocean INTELSAT satellite. On Q however, it was oriented at a azimuth and elevated Otoward the Pacific Ocean INTELSAT satellite. The new antenna, therefore, will probably be used with the Indian Ocean INTELSAT satellite, as reported SECRET NOFORN 25X1 25X1 25X1 25X1 25X1 25X1 3. In addition to the excavation, five high-frequency (HF) horizontal dipole antennas were identified on Onear the two entrances to the adjacent underground tunnel complex (Figure 2). The feed lines for the HF antennas and the INTELSAT antenna lead to vent shafts for the two tunnels, indicating that additional control facilities are probably underground. (S/WN) FIGURE 1.
