Data compression as a service

The Data Compression as a Service (DCaaS) study aimed to bring the benefits of data compression to the experimenters on ESA's OPS-SAT platform. It focused on using the POCKET+ algorithm for the compression of housekeeping telemetry data. The project contained a space component, which performed the compression of provided user data, and a ground component, for the decompression of transmitted user data. Three use cases were selected within the scope of the project: file-to-file, packet-to-packet, and stream-to-stream lossless data transfers.

Tri-band (S/X/K) feed system design for future EO missions
The layout of the 14m X/K-Band antenna developed under a previous GSTP activity will be used as starting point to define the feed specifications. A trade-off among different feed configuration will be performed. After selection of the preferred solution the feed will be designed including diplexers/filters and tracking couplers. Mechanical drawings will be prepared and critical components will be manufactured and tested in order to de-risk the project.
 
In particular, the following activities will be performed:

    Augmented and virtual reality support tool for ground station equipment and telescopes
    Ground Stations and Telescopes are often in remote geographical locations. The local staff do often not possess the required skills and/or knowledge to perform all tasks related to configuration, maintenance and operation of the hardware equipment. As a result, more experienced engineers must travel to the sites to perform the respective tasks.

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

    Persistent Responsive Real-Time Earth Observation small satellite constellation mission (PERTEO) was a study dedicated to providing a global democratic service to support disaster management. Earth observation and satellite-based communications play a key role in supporting 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.

    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).

    CLEANRF: RF Interference Removal for Space Links

    The problems derived from RF interference (RFI) created by men hand, whether generated intentionally or not, remain as one of the main concerns of the space industry.

    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).

    Enhanced Surrounding Awareness and Navigation for Autonomous Vessels

    Autonomous Surface Vessels (ASVs) are rapidly approaching market-readiness, with numerous partly-autonomous and teleoperated systems either under development or already performing operational demonstrations for applications such as bathymetric surveying (SEA-KIT Maxlimer, Deep BV), maintenance of offshore installations (Thales Halcyon), and commercial shipping (Yara Birkeland, Maersk VISTULA-Class).

    Currently, GNSS is the backbone of most Position, Navigation and Timing (PNT) solutions, in providing 24/7 continuous, all-weather, global coverage to an unlimited number of receiver-equipped users. There is an increasing dependency on the availability and reliability of GNSS. However, GNSS is widely known to be vulnerable to an evolving range of threats (natural and man-made, unintentional and deliberate).

    New Microwave Sampling Concepts for Future TT&C Architectures

    In summary, this activity used simulated and analysed parameters for each component to define the requirements for each application. For the flight model, the most important parameters are power consumption, cost and mass of the components. The power consumption and mass of components are acquired from the datasheets. Since space qualification is needed for these components the cost estimation is a difficult task. For example, even for the passive component the price difference between non-qualified, qualifiable and qualified devices is rather high.
