Yakima YAKIMA, USA Latitude: 46.592633, Longitude: -120.528908 The Yakima Research Station was established in the early 1970s inside the 100,000-hectare United States Army Yakima Firing Center, 200 kilometers south-east of Seattle. The facility, located between the Saddle Mountains and Rattlesnake Hills, initially consisted of a long operations building and a single large dish pointing west to enable collection against the Pacific Intelsat satellite. By 1995 the Yakima station had expanded to five dish antennae, three facing west to the Pacific and two, including the original large 1970s dish, facing east. In addition to the original operations building several newer buildings had been added, the largest a two-story windowless concrete structure. The Yakima station has been monitoring Pacific Intelsat communications since it opened, and also monitors the Pacific Ocean area Inmarsat-2 satellite.
