To read the tender notice for this specific challenge, refer to Tender Notice | CanadaBuys Challenge Problem Statement The defence of North America requires resilient, secure, and assured connectivity between assets in space and on the ground. Low Earth orbit (LEO) satellite constellations offer global coverage and low latency, enabling next generation sensing, communications, and command and control capabilities essential to modern defence operations, including those conducted in the Arctic. Defence Research and Development Canada’s (DRDC) Space Low Earth Orbit (LEO) Architectures Initiative is a multi year science and technology (S&T) effort supporting Continental Defence by advancing concepts, technologies, and architectures that enable resilient space information mobility. A key focus of this initiative is understanding how future space based communication systems can be effectively employed to support Canadian Armed Forces (CAF) operations in northern and Arctic environments. This Challenge invites proposals for the design, development, and demonstration of a transportable Optical Ground Station (OGS) capable of establishing high bandwidth optical communication links with satellites in low Earth orbit. The objective is to deliver a representative OGS prototype, that can serve as an R&D platform to characterize performance, environmental sensitivity, and operational trade offs for optical satellite communications in Arctic conditions. Desired outcomes and considerations Essential (mandatory) outcomes The proposed solution must: 1. Support for optical links with LEO satellites at altitudes up to 1,000 km with a minimum data rate ≥1 Gbps under representative link conditions. 2. Be transportable within one (1) 20 foot ISO shipping container, two (2) 10 foot ISO containers, or an equivalent mobile platform, with a maximum total system mass of 15,000 kg, compatible with standard commercial transport methods (e.g., flatbed truck, cargo vessel). 3. Feature a modular hardware architecture with standardized mechanical , electrical and optical interfaces enabling replacement, modification, and upgrade of optical instruments, detectors, modems, and subsystems. 4. Be designed for interoperability with multiple optical communication standards (e.g., CCSDS, SDA, ESTOL ) and demonstrate compatible operation with at least two existing or planned space-based optical communication terminals or recognized reference (“gold standard”) systems. 5. Able to operate in harsh conditions, from −40C to 40C with sustained winds up to 20 knots and gusts up to 30 knots (up to 55 knots stowed). 6. Be deployable and operable on unprepared Arctic terrain (e.g., snow, ice, tundra, gravel, permafrost) without permanent ground preparation or fixed foundations, tolerating surface slopes up to 5° (≈9%) while maintaining required performance. 7. Include mitigation features for snow, ice, and rain. At a minimum, the solution must provide: a) Enclosures supporting ≥30 cm snow load, equivalent to a pressure of 1kPa; b) Environmental sealing against moisture ingress with a rating equivalent to IP55 (as defined by the standard IEC 60529) when the transportable optical ground station is closed; c) De icing or anti icing functionality that does not degrade operational performance. 8. Include instrumentation and logging capability sufficient to characterize optical link performance, pointing stability, availability, and environmental effects (e.g., wind, temperature, snowfall) during Arctic deployment and operations. 9. Include remote monitoring and control capabilities, as well as autonomous link acquisition and tracking 10. Demonstrate that system setup, commissioning, and alignment (excluding site transport and gross positioning) can be completed by two personnel within 8 hours, using standard tools and prescribed deployment procedures. 11. Has a power interface that includes a physical and electrical generator‑mounting slot and accepts multiple standardized external power inputs such as 120 V, 240 V AC (50/60 Hz) US plugs, single‑ and three‑phase sources while autonomously managing power conditioning, conversion, and safe operation. 12. The control room or equivalent section of the transportable optical ground station must be maintainable to a temperature of 20oC ± 2oC during operation. Additional outcomes The proposed solution should: 1. Have atmospheric compensation, link optimization and capacity to establish links in moderate to strong turbulence (C_n^2 > 10-13m-2/3) 2. Provide command and control designed for stand-alone operation or in a network of ground stations, enabling handover and exchanging tracking information to reduce handover downtime. 3. Include battery backup systems for off-grid or remote deployments that allow continuous operation for 2 hours or more. 4. Be capable of establishing high-speed data links at data rates ≥10 Gbps. 5. Have capability for quantum and classical communications such as quantum key distribution. Background and context The defense of Northern Canada and the Arctic region is a strategic priority, where reliable communications remain a significant challenge due to the remoteness and harsh environmental conditions. Optical communications offer a promising solution to connect isolated locations with high-bandwidth links. To advance our understanding of the feasibility, deployment, and operational use of optical communications in these extreme environments, it is critical that the ground station be designed to withstand severe winter conditions. This capability will enable testing and validation of optical links in the Arctic, supporting future defense and sovereignty objectives. Although ground stations capable of establishing optical links with LEO satellites already exist, space-to-ground communication still remains an important challenge. High data rates are achievable, link availability is affected by cloud cover and weather conditions. LEO satellites have short visibility windows—typically less than 15 minutes—with most of that time spent at low elevation angles. At these angles, the optical path through the atmosphere is longer, increasing turbulence and attenuation. Given the SWaP constraints of small LEO satellites, photon link budgets can also be tight. 1) American and European governmental agencies have demonstrated proofs-of-concept: Laser Communications Relay Demonstration (LCRD) Overview - NASA; 2) HydRON: High thRoughput Optical Network | IEEE Conference Publication | IEEE Xplore; 3) The European Space Agency (ESA) has a transportable ground station which supports their optical communications projects: ESA - ESA shipping container's laser link to space; 4) Several optical communications standards are currently under development, including SDA OCT (versions 3.0 and 4.0), CCSDS, and ESTOL. At this stage, it is uncertain which standard will be adopted for future operations. To ensure flexibility and promote interoperability between civilian and military space assets, as well as across international partners, it is essential that the optical ground station be designed with the capability to adapt to multiple standards. This adaptability will support research and development efforts and enable integration with evolving technologies and protocols. 5) In addition to classical optical communications, the integration of quantum communication capabilities is of growing interest, particularly in the context of secure links and quantum key distribution (QKD). Canada’s QEYSSAT mission exemplifies this trend, aiming to demonstrate space-based QKD for enhanced security in future networks. Designing a ground station that can support both classical and quantum optical links will position the system to leverage emerging technologies and contribute to national and allied quantum communication initiatives.
