Abstract
To develop new GNSS service,one solution is to find new GNSS bands.S-band spectrum between 2 483.5 and 2 500 MHz is considered as a potential candidate band.In view of the fact that the spectrum between 2 483.5 and 2 500 MHz has been already allocated to mobile satellite service(MMS),it is important to figure out interferences between different radio services present in the same and adjacent bands.This paper pays attention to assessing the interferences between GNSS and other radio services present in this band.Under the same pseudorange accuracy,the work shows that choosing BOC(6,1) and BOC(6,2) as potential RNSS signal modulations the advantages of smaller emission power and smaller Interference with Beidou-1 are obtained and shows the compatibility between GNSS and other radio services.
