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.

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.
