Introduction At the World Administrative Radio Conference for dealing with frequency allocations in Certain Parts of the Spectrum (WARC-92) (Malaga-Torremolinos@ 1992)@ a secondary allocation was made to the space research service in the 410-420 MHz band for space-to-space operations. These operations@ limited to 5 km from an orbiting manned space vehicle@ are to permit EVA communications between astronauts and between astronauts and primary or base space vehicles. As permanent space facilities are developed in the future@ the needs and requirements for EVA will also increase in order to support many of the planned and envisioned space activities. This is particularly true when considering the construction@ maintenance@ and operation of space facilities. This Report contains update to the work done at (CCIR@ 1991). It shows the EVA communication requirements in the 410-420 MHz band and identifies typical communication characteristics for the fixed and mobile services in the band. The Report contains the interference investigation/analysis from the space research EVA systems to the fixed and mobile service systems in terms of power flux-densities incident at the surface of the Earth. A representative fixed service system and a representative mobile service system are used in evaluating interference to the space research EVA links. The power flux-density (pfd) levels in this Report under ?? (called new proposed PFD limits) are those in No. 5.268 in the Radio Regulations (RR).
