Supporting capability analysis of present spectrum management resources to GNSS IDM in China
【摘要】:Interference detection and mitigation(IDM)of GNSS has become an important cooperation topic in International Committee of GNSS(ICG).Many plans have been implemented for GNSS IDM in US and Europe etc.In this paper the requirements of GNSS IDM are first investigated,together with present spectrum management resource.Based on the investigation,the supporting capability of present spectrum management resources to GNSS IDM plan is analyzed in detail.Analysis is conducted from the following five aspects:radio spectrum management agencies,radio spectrum monitoring contents,radio spectrum management policies,UHF/VHF monitoring network,and spectrum data resource.Recommendations for further modification are also given.All these works are instructive for the development and implementation of GNSS IDM plan in China.
