Terrasat iBUC 1:1 Redundant System

Terrasat IBUC TX 1:1 Redundant System

Intelligent Transmit 1:1 Redundancy System for C, X, Ku & Ka-Band IBUCs

The Terrasat IBUC TX 1:1 Redundant System is a fully integrated, antenna-mount transmit redundancy solution designed to ensure uninterrupted uplink operation for mission-critical SATCOM networks. Unlike traditional rack-mounted redundancy controllers, the Terrasat 1:1 system leverages built-in IBUC intelligence to create a compact, pre-assembled, field-ready solution.

Supporting C-Band, X-Band, Ku-Band, and Ka-Band IBUCs, this system continuously monitors the primary amplifier and automatically switches to the backup unit upon alarm detection — minimizing downtime and protecting SLA commitments.

The IBUC TX 1:1 Advantage

Innovative Hot Standby Mode (no external logic controller required)
IBUC intelligence manages redundancy switching
User-configurable alarm thresholds
Eco-mode for warm standby (reduces power consumption)
Factory pre-assembled & pre-tested
Independent from LNB switching
Higher MTBF vs. legacy rack-based systems
Weatherized RJ45 Ethernet interface
Additional RJ45 port for Rx LNB system integration

✔ Compact integrated mounting plate
✔ Switch-over initiated by secondary IBUC upon alarm
✔ Manual / Auto / Emergency toggle switching

How the System Works

Primary IBUC continuously monitored
Secondary IBUC detects alarms
Automatic switch-over triggered internally
WG (Waveguide) switch pulse generated by IBUC
Integrated interface module handles L-band, 10 MHz, FSK, and alarm routing

Result:
A compact, intelligent redundancy solution without external rack controllers.
