The core mission of this project is to establish a robust and reliable optical link with Low Earth Orbit (LEO) satellites, a multifaceted endeavour crucial for the future of space communication. This involves several key activities, beginning with developing sophisticated tracking systems capable of precisely acquiring and following LEO satellites. Accurate pointing of the optical beam is essential, requiring advanced algorithms and precise control of the Holomondas telescope – with a primary focus on demonstrating high-bandwidth data transmission between the ground station and the satellite, leveraging efficient modulation and coding schemes to maximise data rates. Furthermore, quantum communication technologies will be utilised to investigate methods for transmitting quantum information. This is an ambitious long-term goal aiming to revolutionise secure communication.
Throughout the project, rigorous testing and validation under diverse conditions will be paramount, ensuring the robustness and reliability of the optical link and verifying its performance. This project represents a significant step forward in realising the potential of optical and quantum satellite communication, paving the way for advancements in space exploration, scientific research, and global connectivity through cutting-edge technologies and our dedication to open-source principles.
Benefits
The Holomondas Observatory Upgrade project offers several key advantages over existing competitor systems. Its approach of upgrading the existing telescope system, combined with the use of open-source software and commercially off-the-shelf (COTS) components, results in a highly cost-effective optical and quantum communication solution. Furthermore, the modular fiber-coupling module and open-source software provide exceptional versatility, enabling the system to be adapted to a wide range of missions and requirements, surpassing the adaptability of many current systems. The future-proof design, inherent in its modular architecture, facilitates easy upgrades and expansions, ensuring the system remains relevant and adaptable to future technological advancements. Finally, the project’s focus on secure and quantum communication aligns perfectly with ESA’s ScyLight program and EuroQCI initiative, guaranteeing compatibility and interoperability with future European space communication networks.
Features
The Holomondas project incorporates several key technical advancements. The existing telescope system will be significantly enhanced with a modular fiber-coupling module, a fast-steering mirror, and a high-precision tracking system, enabling efficient optical communication and quantum key distribution. A novel bi-static tracking system, utilising a wide-field telescope and SWIR camera for coarse tracking in conjunction with a fast-steering mirror for fine-tracking corrections, will ensure accurate and reliable target acquisition. For uplink communication, a 1590nm laser system will serve as an L-band beacon/transmitter, adhering to CCSDS O3K standards for seamless compatibility and interoperability. The project also leverages and extends the open-source PyPOGS software library, providing a flexible and adaptable solution for controlling the telescope, laser, and other optical ground station (OGS) hardware components. Finally, a dedicated quantum channel interface will be designed and implemented, paving the way for future exploration of quantum communication technologies and ensuring isolation from the classical communication channel.
