SENSORIS: NewSpace Constellation for Daily Gravity Field Solutions
Satellite gravimetry missions allow to track mass transport on global scales. The main satellite constellations for the gravity recovery are the GRACE and GRACE Follow-On missions. Typically, they provide monthly gravity field solutions which at times is suffering from data gaps. The future MAGIC constellation shall continue the time series and improve especially the spatial…

System-Level CubeSat Propulsion Development for Next-Generation Deep-Space Missions
CubeSats have evolved from educational platforms into capable spacecraft for scientific, commercial, and exploration missions. Extending this capability to deep space and demanding Earth-orbit operations requires propulsion beyond current CubeSat state of practice. Deep-space transfers, precision manoeuvring, drag compensation, and long operational lifetimes demand high specific impulse, high total impulse, and efficient use of limited…

Low SWaP Flight Board for High-Speed On-Board Data Handling, Processing and AI Inference
The continuous increase in payload data volume and mission autonomy requirements is driving the need for increasingly advanced on-board data handling and processing technologies in satellite systems. In particular, next-generation Earth observation, telecommunications, and distributed space architectures require high-performance processing capabilities to enable real-time data reduction, intelligent decision-making, and efficient use of downlink resources. Within…

Cybersecurity Approach for Multi-Tenant Small Satellites
Satellite-as-a-Service (SataaS) provides users with access to satellite capabilities without requiring ownership or direct operation of space assets. This paradigm enables the deployment and execution of applications in orbit without the need for custom hardware or dedicated missions, significantly lowering the entry barrier to space. In addition, SataaS supports rapid in-orbit experimentation, even for applications…

High-Speed Optical Communications for CubeSats: End-to-End Terminal Demonstration and BER Performance Characterisation
Free-space optical communication (FSOC) is increasingly considered for small satellites because it can provide significantly higher data rates than RF while remaining compatible with strict size, weight, and power (SWaP) constraints. This capability is attractive for Earth-observation and science missions where downlink volume is a limiting factor. Despite this potential, CubeSat-class optical terminals are challenging…

Foresail-1 Prime: Early In-Orbit Results and Platform Performance
This presentation reports first in-orbit results from the FORESAIL-1 Prime mission [1], launched in November 2025 aboard the Transporter-15 mission from Vandenberg Space Force Base. FORESAIL-1 Prime is a 3U CubeSat built on a fully redeveloped, mission-specific satellite platform, designed and implemented at Aalto University following a comprehensive re-engineering of the original FORESAIL-1 spacecraft. All…

CubeSat ISR Constellation Mission Tailoring
This paper presents a modelling framework for Intelligence, Surveillance & Reconnaissance (ISR) CubeSat constellation combining optical payload and Software Defined Radio (SDR). The concept satellite is 8-16U depending on the payload resolution and presence of warm-gas propulsion allowing for orbital changes and station keeping extending the operational time. Deployed in 500-km Sun-Synchronous Orbit (SSO), the…
