Defence Product Portfolio
Military-Grade SSPAs and BUCs
Our GaN-based Solid State Power Amplifiers are purpose-engineered for defence satcom, radar and electronic warfare applications:
- Ka-band SSPAs/BUCs — High-throughput amplification for next-generation military satcom systems operating on Ka-band government and military satellite constellations.
- X-band SSPAs — Robust power amplifiers for military X-band satcom, tactical data links and radar applications, with ruggedised options for field deployment.
- Spaceborne SSPAs — Space-qualified amplifiers for military satellite payloads, supporting secure communications and ISR (Intelligence, Surveillance, Reconnaissance) missions.
Defence LNAs
Our X-band LNAs for government and defence deliver exceptional noise figure performance in ruggedised packages, designed for integration into military ground terminals, shipboard satcom systems and airborne receive chains where sensitivity and reliability under harsh conditions are paramount.
Antenna Systems for Defence
Celestia TTI designs and manufactures antenna solutions tailored to military and security applications:
- Active phased array antennas — Electronically steered, multi-beam antenna systems for simultaneous tracking of multiple satellites, enabling resilient multi-orbit communications for command centres and deployed forces.
- SOTM flat panel terminals — Low-profile satcom-on-the-move (SOTM) antenna systems for vehicles, vessels and aircraft, providing continuous connectivity during movement.
- Custom antenna solutions — Application-specific antenna designs including compact terminals for manpack and flyaway deployment, optimised for rapid setup in field operations.
Ground Station Solutions
Complete turnkey ground station systems for military TT&C (Telemetry, Tracking and Command), secure satcom gateways and ISR data reception, including our ATOMS monitoring and control software for automated and remote operation of complex multi-antenna, multi-mission ground infrastructure.
Defence and Security Applications
Tactical Satellite Communications: Deployable satcom terminals and ground stations providing beyond-line-of-sight (BLOS) communications for deployed military forces, with the bandwidth, availability and TRANSEC capabilities that modern networked operations demand.
Intelligence, Surveillance and Reconnaissance (ISR): High-sensitivity receive systems and high-power transmit chains for ISR satellite ground segments, supporting real-time intelligence collection and dissemination across the operational theatre.
Radar Components and Systems: GaN-based power amplifier modules and RF front-end components for ground-based, naval and airborne radar systems, offering superior power density, bandwidth and efficiency compared to legacy technologies.
Datalink Front-Ends: RF front-end assemblies for tactical and strategic data links, integrating transmit and receive chains with frequency conversion, filtering and power amplification in compact, field-serviceable units.
Military Space Systems: Space-qualified RF components and subsystems for military satellite programmes, from payload amplifiers to ground segment equipment, supporting both dedicated military constellations and dual-use satellite architectures.
