Our Team

Intelligent Defence Space Systems

At Infinity Space, our mission is to redefine small satellites for defence and national security. SerenSat‑AI demonstrates how autonomous space assets can enhance operational decision-making by processing data directly onboard. This 2U CubeSat integrates advanced edge AI to filter, analyse, and prioritise imagery in real time, ensuring actionable intelligence reaches operators faster than traditional satellite systems. By autonomously identifying mission-critical data, SerenSat‑AI reduces reliance on ground control, compresses decision cycles, and enables rapid responses in contested, denied, or degraded environments. Its advanced triple-camera payload and neural-network-powered edge processor deliver persistent ISR capability, supporting reconnaissance, surveillance, and intelligence operations with unprecedented agility and resilience.

Defence-Oriented Capability and Autonomy

SerenSat‑AI represents a step change in intelligent space systems for defence. Unlike conventional satellites that transmit raw data for later analysis, this platform interprets complex scenes onboard, dynamically adapting imaging strategies without human tasking.

Its AI-driven autonomy supports rapid threat detection, anomaly recognition, and prioritisation of critical intelligence, providing commanders with timely, actionable insights in operationally challenging environments. The CubeSat’s capabilities are explicitly designed for integration into sovereign and allied space architectures, ensuring secure, trusted, and resilient operations in support of national security objectives.

Autonomous Intelligence for Rapid Response

SerenSat‑AI embeds AI at the core of its operations, enabling onboard analysis of imagery to detect anomalies, prioritise targets, and optimise mission outcomes. By executing intelligence processing in orbit, the CubeSat reduces latency, improves operational tempo, and provides a decisive edge in time-sensitive defence and reconnaissance missions. Its multi-perspective imaging suite ensures comprehensive situational awareness, while onboard neural networks enable adaptive responses to evolving operational conditions.

Its unique triple‑camera system enhances situational awareness by capturing imagery from multiple perspectives simultaneously. Coupled with its onboard AI processing unit, SerenSat‑AI can analyse complex scenes, detect anomalies, and dynamically adapt its imaging strategy without waiting for human tasking. This capability enables rapid, mission‑critical decision‑making for reconnaissance, surveillance, and intelligence operations, even in contested or degraded space environments.

Secure, High-Performance Communications

SerenSat‑AI features a mission-critical communications subsystem optimised for secure and efficient data transfer. Operating from a single 5 V input with low-noise 3.3 V and 4.2 V rails, the transceiver delivers a 5.2 Mb/s payload downlink over UHF while maintaining low power consumption. AES‑128 encryption secures uplink and downlink channels against interception, ensuring mission data integrity and resilience even in contested or degraded space environments. Fully compatible with sovereign ground-station networks, SerenSat‑AI supports real-time command, control, and mission monitoring.

Additive Manufacturing for Rapid Capability Development

Infinity Space leverages advanced additive manufacturing to prototype and validate SerenSat components before full-scale production. This approach enables rapid testing of structural designs, payload integration, and subsystem arrangement with high precision. By iterating quickly, we minimise design risk, ensure mission readiness, and accelerate development timelines for defence operations. This process supports rapid delivery of secure, deployable, and resilient space systems that maintain operational advantage in contested environments.

System Communication Specifications – Secure, Mission-Critical Performance

SerenSat‑AI’s communications system is engineered for resilience in operational environments. Running from a single 5 V DC input with low-noise 3.3 V and 4.2 V rails, it ensures stable, interference-free operation. The transmit subsystem draws 5.12 W while receive mode consumes only 0.24 W, optimising endurance for long-duration missions.

With a high-speed 5.2 Mb/s payload downlink over UHF, the system delivers reconnaissance imagery and intelligence products rapidly to authorised ground stations. AES‑128 encryption secures all uplink and downlink channels, protecting mission data from interception or tampering. This combination of efficiency, speed, and robust security ensures uninterrupted communications throughout defence and national security operations.

OVM StarTracker – Precision Navigation for Defence Operations

The integrated OVM StarTracker provides power-efficient attitude and angular velocity determination, optimised for CubeSat-class defence missions. It enables precise orientation control in Low Earth Orbit, ensuring stable targeting for high-resolution imaging and reconnaissance payloads. This module enhances mission assurance, guaranteeing accurate data capture and consistent performance in routine and contested environments, setting a new standard for reliable, defence-ready satellite navigation.

Why Onboard Intelligence Matters in Defence Operations

As the number of satellites and space missions accelerates, onboard intelligence has become critical to managing finite resources such as power, bandwidth, and secure communication windows. Traditional platforms often transmit vast volumes of raw data to Earth, creating bottlenecks, delays, and potential security vulnerabilities. SerenSat‑AI transforms this model by processing and analysing data in orbit, in real time. This enables the satellite to autonomously prioritise mission‑critical information, minimise unnecessary transmissions, and deliver timely, actionable intelligence, maintaining operational advantage even in contested and degraded space environments.

Why Onboard Intelligence Matters in Defence Operations

SerenSat‑AI’s avionics suite is built around a Texas Instruments TMS570 microcontroller, providing fault-tolerant, robust processing for mission-critical operations. External memory includes a 128 Mb NOR flash module for secure, high-integrity data storage. File uplink and downlink are managed via the CCSDS File Delivery Protocol (CFDP), ensuring standards-compliant, reliable communication. A secure over-the-air bootloader allows rapid in-orbit firmware updates. Persistent configuration tables are stored in MRAM, supporting three independent configurations for mission assurance. The system runs FreeRTOS v10 for deterministic performance, while an integrated NovAtel OEM719 GNSS receiver provides precise positioning and timing, enhancing situational awareness and operational effectiveness in routine and contested space operations.

Turning Images into Intelligence – AI-Powered Analysis in Real Time

SerenSat‑AI converts raw imagery into actionable intelligence onboard. Its AI system autonomously detects priority features such as vehicle movements, infrastructure changes, maritime patterns, and environmental anomalies. By processing data at the source, it minimises unnecessary transmissions, conserves bandwidth, and accelerates decision-making for defence and national security operations.

This embedded machine learning pipeline ensures intelligence is delivered securely, efficiently, and in real time, maintaining operational advantage even in contested or degraded space domains.
