International Wireless Operation and GNSS Spectrum Compatibility Analysis in Band 960MHz to 1610MHz

The spectrum compatibility analysis among GNSS and that between GNSS and other operations are firstly advanced in this paper.The interference of GPS and GALILEO to BeiDou is calculated with interference coefficient in the beginning.Consequently,according to constraint conditions for transmitter frequency tolerances and maximum permitted power levels for spurious or spurious domain emissions set by ITU,the potential interference between other operations and GNSS is defined and is employed to obtain the interference between other operations and BeiDou B1,B2 and B3.Finally,spectrum compatibility of BeiDou in 960 MHz~1 610 MHz is given in the paper.The analysis method of spectrum compatibility proposed here hold for the spectrum compatibility of other operations.
