6.0 Plan for Instrumentation Complex 6.1 The existing instrumentation capabilities on the Eniwetok Atoll consist of the Optical and Photographic coverage, the All Weather Impact Location System (AWILS), the SPN-8A Radar, and the GMD-1B. The Optical and Photographic coverage consist of three Mobile Optical Tracking Units (MOTU), three Askania Anetheodolites, and Optical and Photographic MILS (Missile Impact Location System). The Optical and Photographic MILS consist of a series of 35mm cameras and transits on Runit Island, Parry Island, and Eniwetok Island. These systems are presently operational in fair weather and daylight hours. The AWILS consist of seven hydrophones which are anchored at the bottom of the lagoon and attached to buoys at the surface. This system is installed and presently undergoing evaluation. The AN/SPN-8A Radar was installed on Elmer Tower (Parry Island) as an interim impact location system to meet an operational requirement. This system is installed and is presently undergoing evaluation. The GMD-1B provides data on the upper atmosphere. Data from the CMD-1B is raw and involves lengthy computations before it can be used. This system is presently operational. In addition to the existing instrumentation capabilities, a recovery capability does exist at Eniwetok. 6.2 Systems planned for the kniwetok Atoll in FY 66 consists of the installation of a Meteorological Sounding Rocket Facility and the conversion of the GMD-1B to a GMD-4. Prior to FY 67 a payload for the meteorological rocket which is compatible with the GMD-4 is expected to be developed. Therefore, a radar to track this pay- load would not be required. -~13-
