Dedicated Carrier and Spectrum Monitoring System (CSM)

  • Comprehensive monitoring capabilities across one or more satellites

  • Multiple ground stations and beams can be easily supported

  • Centralized monitoring and control from a satellite network control center

Decimator RF Spectrum Analyzer Carrier Monitoring

  • Basic carrier monitoring anywhere in the world with a standard Internet connection

  • Calian’s Decimator product can be used without the need to deploy additional instrumentation

  • Use Calian’s Decimator product standalone or integrate it into your solution

Scalable System

The system is scalable to support multiple satellites, multiple satellite beams and multiple gateways or ground stations depending on your needs.

The overall system can be operated from a network operation center to control and monitor your satellite network from a central location.

Mon-A-Co Integrated Carrier Monitoring System

Carrier monitoring capabilities for both existing and new users of Calian’s M&C product.


  • Downlink EIRP, center frequency and C/No for a carrier
  • Uplink EIRP and center frequency of a carrier
  • Downlink EIRP in a specified bandwidth
  • Uplink EIRP in a specified bandwidth
  • Full-spectrum analysis, including identification of spurious carriers
  • Satellite noise
  • Reference carrier calibration
  • Doppler corrections of measurements based on orbit model predictions
  • Calibration tables to enhance absolute measurement accuracy

CSM Architecture

The architecture of the Carrier and Spectrum Monitoring System (CSM) is designed to be flexible, allowing the system to adapted to all types of installations large or small.

The CSM was designed to be scalable so that additional monitoring can be added as your monitoring needs grow.

The heart of the measurement system is our Decimator product that allows multiple measurement points to be monitored at each teleport, gateway, spot beam or antenna location. Frequency converters down-convert the satellite frequency band to the L-band input range of the Decimator.

The CSM consists of the three different components including:

  1. Network Control Center Equipment
  2. Gateway Monitoring Equipment
  3. Spot Beam Monitoring Equipment.

The CSM components can be combined to provide the right monitoring solution for your configuration.

CSM Components

  • Network Control Center Equipment

    Provides the main user interface for the system for carrier alarming. Aggregates carrier measurement results from all the monitoring sites for presentation. Consists of computer equipment and Calian’s software.

  • Gateway Monitoring Equipment

    Provides monitoring of uplink and downlink carriers at a gateway or ground station. Provides a local user interface for gateway staff. Measurement results are forwarded to the network control center. Consists of computer equipment, measurement instruments, switching and Calian’s software.

  • Spot Beam Monitoring Equipment

    Provides monitoring of signals in a remote spot beam or another remote location. Consists of Calian’s Decimator measurement instrument that forwards measurement results back to the network control center.
