At the heart of Infinity Space’s mission is a bold commitment to redefining the role of small satellites in defence and security. SerenSat‑AI marks a new chapter in intelligent space capability — one where satellites don’t just observe, but think. This advanced 2U CubeSat integrates artificial intelligence directly into orbit, enabling real‑time decision‑making, autonomous imaging, and onboard analysis far above Earth. Equipped with a triple‑camera payload and edge‑processing architecture, SerenSat‑AI represents a shift toward smarter, faster, and more resilient satellite systems, delivering rapid, actionable intelligence to support reconnaissance, surveillance, and national security operations in the contested space domain.

A New Chapter in Defence Space Innovation — SerenSat‑AI

SerenSat‑AI represents a major step forward in intelligent space systems for defence and security. More than just a satellite, this advanced 2U CubeSat integrates artificial intelligence at the core of its operations, enabling it to observe, interpret, and adapt in real time. By autonomously determining which data is mission‑critical, SerenSat‑AI reduces reliance on ground control and accelerates the delivery of actionable intelligence from low Earth orbit.

This capability marks a fundamental shift in how space assets are designed and operated for national security. Traditionally, satellites have relied heavily on ground‑based processing, transmitting large volumes of raw data for later analysis. SerenSat‑AI breaks that model by using onboard edge computing and neural networks to filter, analyse, and act instantly. This ability to process and prioritise data in orbit enhances responsiveness for reconnaissance, surveillance, and intelligence missions, strengthening operational advantage in the contested space domain.

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.

The avionics suite is built around a Texas Instruments TMS570 microcontroller, delivering robust, fault‑tolerant processing for mission‑critical operations. External memory includes a 128 Mb NOR flash module for secure, high‑integrity data handling, while file uplink and downlink are managed via the CCSDS File Delivery Protocol (CFDP) to ensure seamless, standards‑compliant communication. An integrated bootloader enables secure over‑the‑air firmware updates using CFDP, supporting rapid capability upgrades in orbit. The non‑volatile configuration table, stored in MRAM, retains up to three independent tables for persistent, reliable system configuration. Running on FreeRTOS v10, the platform benefits from a proven real‑time operating system optimised for deterministic performance. For precision navigation, an integrated NovAtel OEM719 GNSS receiver provides accurate positioning and timing, enhancing situational awareness and operational effectiveness in both routine and contested space environments.

Turning Images into Intelligence — AI‑Powered Analysis in Real Time

SerenSat‑AI employs advanced onboard artificial intelligence to convert raw satellite imagery into mission‑ready intelligence instantly. Rather than transmitting vast volumes of unprocessed data to ground stations, its AI system analyses imagery in orbit, autonomously detecting priority features such as vehicle movements, infrastructure changes, or environmental anomalies. This real‑time interpretation enables the satellite to prioritise mission‑critical data, ensuring secure, efficient, and timely communications.

This capability not only conserves bandwidth but also accelerates decision‑making for defence, reconnaissance, and national security operations. By embedding machine learning directly into its imaging pipeline, SerenSat‑AI marks a decisive step toward fully autonomous space assets — where intelligence is processed, filtered, and acted upon at the point of capture, maintaining operational advantage even in contested or degraded space environments.
