RES156 – 248 – ANNEX TO RESOLUTION 156 (WRC-15) Off axis e.i.r.p. density levels for earth stations in motion communicating with geostationary space stations of the fixed-satellite service in the frequency band 29.5-30.0 GHz2 This annex provides a set of off-axis e.i.r.p. levels for earth stations in motion operating in the frequency band 29.5-30.0 GHz. Earth stations in motion operating and communicating with geostationary space stations in the fixed-satellite service transmitting in the frequency band 29.5-30.0 GHz shall be designed in such a manner that at any angle, θ, which is 2 or more from the vector from the earth station antenna to the associated satellite (see Figure 1 below for the reference geometry of an earth station in motion compared to an earth station at a fixed location), the e.i.r.p. density in any direction within 3 of the GSO, shall not exceed the following values: Angle θ Maximum e.i.r.p. per 40 kHz* 2° ≤ θ ≤ 7° (19 − 25 log θ) dB(W/40 kHz) 7° < θ ≤ 9.2° −2 dB(W/40 kHz) 9.2° < θ ≤ 48° (22 − 25 log θ) dB(W/40 kHz) 48° < θ ≤ 180° −10 dB(W/40 kHz) * Other levels may be coordinated and mutually agreed between affected administrations (see also resolves 1.1). _______________ 2 See also Report ITU-R S.2357 for ease of reference.
