I-3BGSO satellite system brought into use status

The frequency assignments of the Inmarsat networks identified above have been brought into use.

I-5GSO space station maximum pfd versus latitude and longitude at 40,000 feet above the Earth’s surface (worst 1 MHz)

I-8GSO/non-GSO satellite system spectrum

The level of spectrum emission in each 1 MHz relative to the spectrum value at the worst 1MHz of the whole band (1164-1215MHz) is provided below as the Spectral Adjustment Factor (SAF) in dB.
