Data compression as a service

Telemetry data is the most valuable asset provided by any spacecraft. Increasing the data amount sent from space to ground increases a mission’s value, but often this comes with increased costs. Compression of Space generated data provides great benefits to both the large ESA missions by increasing the mission science throughput and small missions (which typically have low bandwidth) by increasing the traditional low downlink rates of these missions. One solution to this problem is the POCKET+ lossless compression algorithm, which is currently being standardized by CCSDS.

A Comparative Study Of High-Level And Low-Level Implementations Of Deep Learning Models For Spacecraft

Mission Control deployed a low-level implementation of the OPS-SAT SmartCam model using a Field Programmable Gate Array (FPGA), comparing against a high-level CPU model using Tensorflow Lite. Experiments showed that the FPGA implementation reproduced the precision and accuracy of the high-level model, while running at a slower speed. Further optimizations of the FPGA are expected to close the gap in timing and unlock new methods for deploying deep learning on spacecraft.

MoBaTe – Enabling Model-Based Testing and Automated Test Case Generation for Ground Segment Data Systems

The driver behind the MoBaTe activity was to propose ways to improve the current software development and validation lifecycle using MBSE techniques to shift some of the system validation activities to the early stages of development. The roadmap to achieve this included identifying strategies, required model properties, modelling tools and languages needed to move from a requirements-based approach to a model-based approach. All this considering existing and established workflows and tools currently used by the Agency.

AI AT THE EDGE : DEEP CUBE SERVICE IOD/IOV

OPS-SAT mission is a key element for operational validation in flight (or IOD/IOV) of the DeepCube service of Deep Learning at the edge that our company is preparing with the support of the GSTP programme (GSTP Make, ESA-CNES) and the R&D performed in the CORTEX project (Permanent Open Call EOEP-4, ESA/Phi-Lab, https://esacortexproject.agenium-space.com). The goal of the proposed experiment is to execute on-board the inference of the simplified models defined in those projects.

Beyond the Mission Paradigm: Federated Reconfigurable Infrastructure via Edge Devices in Space (FRIENDS)

Early space missions consisted of bespoke components communicating with facilities on Earth. Today this model has been updated with off-the-shelf components and reusable launch systems that lower mission cost into low-earth orbit. Extending this model to develop a sustainable off-earth economy requires bringing the concept of reconfigurable computing agents to deep space.

PERTEO: Persistent Real-Time Earth Observation for Responsive Disaster Management

Persistent Responsive Real-Time Earth Observation small satellite constellation mission (PERTEO) is a study dedicated to provide a global democratic service to support disaster management. Earth observation and satellite-based communications play a key role to support disaster management targeting responsiveness and the persistence of the service. In the terminology of on-demand Copernicus services, responsiveness is determined by the lead-time and latency. The persistence is determined by the availability and by the revisit time of the service.

ENCORE – In-Orbit Servicing of an Operational Spacecraft

The market for life‐extension services for GEO satellites is expected to remain healthy over the foreseeable future: over the last 20 years, an average of 22 new GEO satellites have been launched per year. In total, ClearSpace expects there will be 370 potential Client satellites that will reach their end of life due to the limited fuel they have remaining over the 2026‐2041 period. ClearSpace believes a strong market penetration rate is feasible, as more than 30% of all the potential satellites belong to just 7 satellite operators.

Absolute Navigation at Sub-cm Level - Phase 2

Currently GNSS Systems provide services for instantaneous absolute positioning accuracy of a few meters, assuming no local obstructions above 5-10 degrees elevation, based on the navigation signals broadcast by a MEO constellation.

POSITION, NAVIGATION AND TIME TRAFFIC LIGHT (PETAL)

The objective of the proposed PNT Traffic Light project is to develop a continuous 24/7 performance monitoring tool for EGNOS/GNSS (and particularly for GPS, GALILEO and EGNOS) on the northern and arctic region of, at least, EGNOS coverage area. In addition to just EGNOS, the tool shall be designed to support assessment of the performance of also other GNSSs (at least GPS and Galileo).

On the Use of Mega-Constellation Services in Space

This activity investigates how mega-constellations can be used to provide low-Earth orbit (LEO) spacecraft with broadband low-latency services, a novel Concept with potential to disrupt spacecraft design, operation, and performance by allowing spacecraft to access mega-constellations’ enormous resources (Tbit/s throughputs) and global coverage at a lower cost than traditional data relay systems and ground station networks (two to fifty times cheaper, that is, a few hundred to a few thousand dollars per month for a daily net capacity from hundredths of Gbit up to almost ten Tbit).
