Monitoring and direction finding system

Fixed radio

Monitoring and direction finding system

Fixed monitoring stations are the main construction form of provincial radio monitoring facilities,mainly used to realize long-term monitoring of the electromagnetic environment in the covered area.Based on the different application scenarios and differentiated business needs of users,the company builds standard/customized fixed monitoring stations forusers,which meet the corresponding requirements of Category I/II/II/IV fixed monitoring stations in the “Provincial Radio Monitoring Facility Construction Specifications and Technical Requirements(Trial)”.Meanwhile,the stations fully comply with the “Radio Management Integrated Platform Architecture and Application Specifications” and “Ultra-short Wave Monitoring and Management Service Specifications”,and integrate monitoring equipment services and frequency station data services,thus realizing seamless connection with the radio management integrated platform in the province where the stations are located.

PRODUCT CHARACTERISTICS

SYSTEM COMPOSITION

The system offers categoryI-IV stations and comprehensive solutions forspecialized monitoring systemsthat comply with the “Provincial Radio Monitoring Facility Specifications and Technical Requirements”,and provides whole-processoverall delivery including equipment research and development,production,integration,installation,set-up,debugging as well as after-sales operation maintenance.

With the monitoring frequency range covering 9kHz-26.5GHz and the direction finding frequency range covering 20MHz-18GHz,the system supports the ability to expand the short-and medium-wave and microwave frequency bands, and allows the integration with monitoring and direction finding equipment developed by Dagongbochuang and equip- ment from mainstream foreign manufacturers such as R&S,TCI,and Thales.
