SPS Effects on Optical and Radio Astronomy

FIGURE 3 - Space station distance from terrestrial transmitter for interference power equal to receiver noise power 4.4 Potential interference to deep-space station receivers from near-Earth satellite transmitters Near-Earth satellites typically have antennae directed to the Earth or to other satellites. Interference with deep-space station receivers may occur for those brief periods when the satellite antenna is directed near the ecliptic plane. As received at deep-space stations, signals from satellites will usually be relatively weaker than those from earth stations. 5. Sharing considerations: space-to-Earth bands Table VIII and the following paragraphs consider the possibility of interference in the deep-space research space-to-Earth bands.
