Redundancy Systems

Satcom Redundancy Systems

The array of redundancy systems available from Comtech Xicom Technology has grown with new customer requirements and the introduction of new redundancy control approaches. Xicom redundancy systems can be configured for both rack-mount and antenna-mount operation.

For amplifier redundancy switching, the redundancy function can be located in the amplifiers or a separate controller. Amplifiers can accommodate simple systems while separate controllers are required for more complex systems. Irrespective of where the redundancy or switching decision is made, the decision is dependent on the status of the amplifiers.

All Xicom systems rely on summary fault signals via hardware for amplifier status, i.e. summary fault relay contacts, as it provides the most robust and quickest way to do the automatic switching. Additional amplifier monitor and control is communicated between amplifiers, and controllers if required, via serial or Ethernet communications.

  • 4 way continuous power system
  • 8 way continuous power system
  • Custom systems

High power and assured availability make the Xicom Continuous Power System a hit with customers

For high power requirements, combining amplifiers is often required. These higher power systems are generally for gateways so redundancy is also a must. The traditional redundancy approach is to have another high power amplifier system and switch between them, or have individual 1:1 or 1:2 amplifier systems combined. In all the 1:1 approaches, half of the amplifiers are not contributing to the output power while consuming AC power.

Another undesirable aspect of these switching approaches to redundancy is that the transmission is interrupted. An innovative approach developed by Comtech Xicom Technology called the Continuous Power System (CPS) which overcomes the problems associated with the traditional approaches just described. The CPS approach is applicable to both indoor and outdoor SSPAs and TWTAs.
